Does your 05-09 Mustang Needs a NEW Interior Fuse Box? (Smart Junction Box/Anti-Theft Fuse Box)
HTML-код
- Опубликовано: 13 сен 2024
- This Video will show you how to replace your interior Fuse Box in your 05-09 Mustang (Also known as SJB-Smart Junction Box or Anti-Theft Fuse Box)
How to tell if your box went bad?
If you have a water leakage in the passenger side, you most likely need a new one.
A way to tell if you need one (Self Diagnose)
-All electrical systems inside are on 24/7
(ex. Stereo, power windows, dome light, trunk light, etc...)
-All electrical is off even tho you're car is on, Stereo wont turn on, power windows unresponsive, dome lights off, you're unable to turn on headlights, tail light, brake light, etc...
This generation of mustangs have a common issue where the passenger side gets water leakage due to drainage getting clogged up due to leaves and other debris, Unclog every 6-12 months to avoid this during raining season!

I'm getting a lot of questions regarding the BCM needing programming after replacing. Short answer is NO....not if it's a used unit that is, I had replaced the BCM (SJB/Anti-Theft Fuse Box) twice on this mustang and both times I just swapped them out without needing a reprogram. HOWEVER I cannot guarantee that this is the case for everyone! I know you will definitely need programming if installing a brand new fuse box for sure but as far as my personal experience I did not need programing after replacing mines. (Both parts were bought off of eBay used)
Hope this helps a lot of you and hopefully it cleared some concerns about this needing programmed.
I’m trying to find where I can order one new or would I have better luck trying to order one off eBay?
@@adriancavazos7434 Finding one new is extremely difficult, even through the dealership (could be lucky and your local dealer might be able to get their hands on one) but other than that, buying it used on eBay would be your faster option, they always have those available there but you want to make sure the part number on your original box matches with the one you are purchasing
Thanks for the advice appreciate it so much!
@@dany5.084como se llama la caja para comprarla por q tengo ese mismo problema con mi mustang
@@dany5.084 how do you know which part it is? It has many numbers and letters, how do I know which one is correct?
Nice job... Ford has been paying millions of dollars to try and hide all of their screw ups on these vehicles and not have to take responsibility for their stupidity. Even these cars brand new were having that same exact battery issue, among all the other problems. So when people were having the cars looked at by Ford (because they obviously were still under warranty) the mechanics were told to just replace the battery and tell them it was a bad battery. That was never the case.. It took me 2 years to finally figure out all these problems so that l could actually rely on my car being able to start and work properly. I never could find any videos or suggestions on any forums that had the actual right answers to the problems. And that was due to Ford paying to have them removed from youtube and any online forums. Cheaper than recalling all the cars and fixing their own stupid mistakes. The battery issue is a problem in most from 04 to 08 l believe. The problem is the Shaker stereo. It continuously drains the battery even when the vehicle is off. I hooked up my elec tester and watched how much was being drained. Then l started pulling fuses 1 by 1 until l found the 1 that stopped the drain and it was the radio fuse under the hood. So l wasn't going to pop my hood to pull it every time l got out, so l actually just wired that fuse to a switch in my glove compartment so l can turn that one fuse off and turn it back on when l get in. You won't lose the memory settings or presets but it will always come on to am radio when you turn it on. Better than having dead batteries all the time. And the water that leaks onto the computer actually mostly comes the mirror and also from the weather seal above the passenger door window. So after l cleaned up all my fried pins and soldered in some replacements, l taped a piece of plastic poly above the computer and it goes over the comp all the way down to the floor and haven't had water get on it since. Thanks for the video showing people exactly whats going on with their mustangs. Otherwise people are trying everything that some random person will suggest to try replacing. And that gets really expensive when none of it is fixing the actual problem.
Thank you too brother for the jewels you dropped
2 years later and still relevant^
After dealing with this and researching this for the past year and a half, in short I've gathered ford knows about this but refuses to admit it. Problems range from the fan relay burning the the point of melting and fusing together to the throttle thinking its wide open when its not. No doubt lots of liability if ford ever admitted to their mistake. Replacing mine soon with fingers crossed. Whatever the issue its no coincidence everyone experiences electrical issues, just sucks for people like myself who have had extra wear and tear on the motor from these problems causing more severe ones and dumping money in between. Feel very bad for the ones who may have lost their life or a loved one due to the issues I've witnessed such as the throttle thinking its wide open (and STUCK wide open unless the whole car is shut off) or all the lights and dash shutting off while still maintaining speed and running fine (or even better than before) in the middle of a night drive. 2008 Mustang GT owner. Ive tried manual switches for the relay ran outside of the fuse box, 60 amp relays, tried three brand new fans and connections, new water pump, new alternator, new batteries... still face the same issues and get a 'check charging system' message every-time I drive.
This what happened to my 07 Ford Mustang GT..$900 later it's at the Ford Motor shop now...I removed the plugs from the cowel panel completely...wish I saw this video at first...would've saved me a lot of money..thanks for the video
Same I spent 850$ on a diagnosis and fuel pump replacement at the Ford dealership only to bring it back 4 times before them telling me it’ll be $700+ for them to replace my fuse box -_- why wouldn’t they tell me that was the problem when I first got the diagnosis??? I hate dealing with them
Just ordered my fuse box $70.00 I knew that was the problem
Thank you

Tengo un Mustang 2006 le puse una caja de fusibles del 2007 pero no funciono
Regarding the water leaks mentioned at the end, that is all true, but there's a second(perhaps more) possible source for major water leakage into the passenger foot well. I traced the problem myself several years ago when the amount of water was crazy after every time it rained and this comment is for anyone who may see this and either has that second leak or does in the future. For me, and I believe Ford has a bulletin that backs this up, it was the holes for the clips for the cowl cover. The clips have insufficient gaskets that don't seal well and deteriorate quickly. I believe they changed the gasket design for '07 or '08. For my '06, I used a weatherstrip adhesive to reinstall the clips. RTV would probably work well too. Of course, it's worth mentioning that there's a defect in the body of the car since the water shouldn't drain inside the car anyway, but that's out of our hands.
Good to see what's involved here since I think my SJB is finally going bad. I've been lucky that it lasted so long for me(14 years), but I also tried to protect sensitive parts from water after I noticed a lot of water coming in. I used old plastic comic book bags I had around to direct the water away from important connectors and such. Not only am I getting some accessories turning on by themselves, my parasitic draw is high and killing my batteries. I got two warranty replacements, which was very lucky. Thanks for showing this and I may be doing this same fix very soon.
Also there is weather stripping behind the plastic window/ door seal that goes bad. Pull the rubber window seal down and remove the plastic piece it snaps to and replace it. That’s where a lot of water can leak down to the passenger side
Wifes Stang had the clogged drains problem. I modded the grills at the windshield with window screen to keep the leaves out. Repainted everything black and you can't see the mod.
nice. very clever. im gonna do the same now. thanks.
Good video Dany, I had this problem on my 06 GT two years ago. I screwed myself by taking it to a dealer, by the time I was done I was out 1100 bucks, however they did seal and water proof everything. But your video was very helpful, next time I'll be doing it myself if I have too. The dealer said I should never have the problem again, but I trust them about as far as I could throw them. Thanks again brother.
Amazing - I have a 2006 convert.... lights and other issues - will try to clean first and then replace if I need to. i just priced out a new SJB and its $825 CDN + $250 shop time for programming. I will let you know how it goes. thanks !
Awesome video. No right running lights. Got a used sjb on eBay and fixed problem. Did have to google how to reprogram my key fobs but that was easy to
Glad this video was able to help you out :)
And dome light doesn’t work but I can live without that
@@tkkak1932 have you checked the bulb out the fuse
Need some help! Let me start from the beginning. We had a rain storm which led to water getting into my passenger side my whole entire fuse panel bcm was soaked. My flashers was going off on its own. I took it out & took it apart, dried it out then sprayed electrical cleaner let it dry. Then repeated the process with the wire harness connections that connects to the fuse panel bcm. Once I was done with that I hooked it all up and I got a non start issue. Checked all fuses/ relays all was good. Checked battery with meter all was good. Checked starter all was good long story short I did a general basic diagnostic. All was good. I proceeded to lean towards that it was a faulty Fuse panel bcm so I ordered another one that matches mine. I received my car now starts and runs fine and my flashers are back to normal. Everything looks to be functioning correctly besides one issue that I did not have before all this! My car won’t get out of park now! Only way I’m able to take it out of park is the little bypass on the side of the shifter that you push in. Any suggestions to what may be going on now? Yes I checked the fuse again all is good I also checked the break light switch. All is good.
Funny enough, I experienced that same issue the second time I had to replace the fuse box, the way I was able to "fix" this was disabling the shift interlock function on the vehicle. (I ended up having a mechanic doing this for me since at the time I didn't knew how to do this) the other option my mechanic told me (the expensive option) was replacing the entire shifter but wasn't guaranteed it'll fix the issue, so I decided to have him disable the shift interlock. but I must WARN YOU! If you go this route too, you're car will loose that function which in short terms, you'll be able to start the car up no matter what gear it's in which can be dangerous if you have the vehicle in drive or neutral. can roll away (the shift interlock is a safety feature, it prevents the car from starting if 1)the brakes aren't being applied and 2) the vehicle is not in park, therefore you will be messing with something that will disable a safety feature, do this at your own risk) other than that, this was the route I went and haven't had an issue since.
Hope this helped out and good luck.
Please add the OEM PART # ASAP. Many thanks.
THANKS! I just swapped the SJB on my 2008 and the remote key fobs work again! NOTE: after the swap I had to program each fob to the new SJB by doing the ignition on/off 8 times sequence - which only took about 30 seconds (search youtube for full instructions if needed).
So y bought the sjb used did you have to take it to ford to reprogram?
@@angelrios5364 No. I was worried I would have to have it reprogrammed but everything worked fine. I was told the key is to get a replacement SJB that has the same part numbers as the one it is replacing. A SIDE NOTE: According to a Ford dealer who used my VIN to look up the SJB part number for my mustang - the one I replaced was not the original part number. But apparently is was fully compatible and is working fine. To be safe, if you buy a used one off of ebay make sure they indicate it has been tested/works and accept returns if there is any issue. Best of luck with whatever you do!
@@edbreyer thanks i will try it . I matched numbers but wasn't sure if it would plug and play so I been having it sitting here collecting dust trying save up to pay the dealer 900 just to reprogram and acouple more hundreds to install if it works man you saved me a whole lot of money lol
@@angelrios5364 If the replacement one you bought came from another Mustang then it definitely has some sort of programming - and if the numbers match - based on my experience - it should work. However, if you bought the replacement SJB from a Ford dealer than I don't know if it will need programming to work. I suggest you just connect the replacement one and see how it works. Worse case, it does need to be programmed and then you just swap the current one back in until you have the money saved for reprogramming. I can't recall if I disconnected the battery when making the swap - but seems like you'd want to ensure all the power is off before disconnecting/reconnecting the SJBs. Post a follow-up to let us know how it all turns out - GOOD LUCK!
You don’t have to replace this to get your key fob to reprogram the key… all you do is just reset the key fob with turning the key 8 times back to back leaving it on on the last
Thank you, thank you Dany !! Saved a bunch of money, easy to follow directions, did I say THANK YOU!
you can use contact cleaner to clean it up inside and out so you dont half to spend all that money also wrap in in a few plastic bags so it wont get wet agian
I tried this and it fixed my one issue but after 5 minutes it messed up again. Tomorrow I get a brand new set of fuses and will replace all and try again one more time
@@CorruptTime did it work better the second time and what was your issue?
I dont think I've ever had such a large smile on my face when someone has said..."my stero is working!"
Like....I dread quiet rides.
Man your man hero right now! God bless 😇
I'm glad to hear that 😁👍
My mustang dash lights are starting on and my anti theft keeps coming on car won’t crack
Someone needs to make bank off of a relocation kit!!
Easier said than done would have to re-wire the whole car
i reb=cently went to my FORD dealership and they gave me a print out of all SJB that are compatiable with mine FYI. the list was like 20 different ones to choose from
Mine won’t come out of park when I change it ??
Very very helpful, you did an outstanding job of explaining and showing this, thank you
I forgot to mention that in addition to addressing the water leak issue (removed clogged drain plugs in firewall, replaced/sealed cowl tab clips and replaced foam stripping under black plastic trim around door openings) - I also draped a sheet of clear plastic over the top of the SJB and let it cover both the front and back - so if water does drip in, the plastic sheet will hopefully keep it out of the SJB.
That’s my problem
@@DonnellKane The fixes I performed on my 08 are still working - so maybe give them a try!
@@edbreyer did you replace it or just stopped the leak
@@DonnellKane I first stopped all the leaks then replaced the SJB. I'll post below a previous post on another forum with mor edetails...
>>> I resolved most of my issues by replacing the SJB/BCM with a used one from ebay - BUT first make sure you've resolved any water leak issues which is the main cause of SJB/BCM problems. I'll paste below the verbiage I posted on another thread outlining what I did. Hope it helps!
-----------
Make sure you have sealed all the water entry points.
1) I removed the rubber drain flaps below the windshield cowl that would sometimes get clogged and allow that area to fill with water and enter via the cabin air filter - no chance of clogging now.
2) I also ordered/installed a replacement set of the heat sealing tab sockets that the tabs of the plastic cover under the wipers insert when being installed.
3) I replaced foam sealant strips under the plastic trim around the upper door frames.
4) (In case all that fails and there is still a leak) I wrapped a clear plastic sheet of plastic over the top, back and front of the BCM/SJB which should keep water from getting into the box/electronics.
ALSO, Don't be afraid to buy a used BCM/SJB - as long as you: 1) make sure the numbers match exactly what you have now. 2) You buy it from a source that ideally tests it AND allows returns if it doesn't work. That's what I did (via ebay no less) and it has worked perfectly without any new programming. It felt risky but the $250 was much less than the $1,000+ the Ford dealer wanted for a new one and programming.
@@edbreyer appreciate you bro
I'm having all those issues plus my headlights and signal light. The car cranks fine and I can put it in drive reverse etc. But other than that everything you said is spot on. Will the smart junction box make my headlights and signal light work with all the other issues you named? Cause it's doing exactly everything you Said (headlights and signal included)
I've got an 06 and my box like his was bad and I replaced it to find out my headlight harness and under the hood fussbox was fried
just wanted to add a important note, on my 05 recently the wiper motor quit working ,i replaced it with a 120 $ autoparts one they all may be remanufactured at that price ,it lasted two weeks ,i took the new rplacement motor wiring connector cover off and everything in the circuit board was fried ,im pretty sure the remanufactured one i purchased ,all they did was sand blast repaint and resell a bad motor , it was a pain trying to figure out why it quit working so if your wiper motor quits working and you have allready pulled the factory mistake drain plug below the motor and eliminated the fish bowl drown the wiper motor situatioin and your two fuses for the wiper motor are good ,remove the wiper motor and pull the electrical cover off my replacement ,the grease looked twenty years old ,and its circuit board was fried,i wasted time tearing dash apart to replace the wiper switch first
I switched the fuse box and my head lights and tail lights stay on now even though my car is off, I have to disconnect my battery. Anyone advice ?
wonder if there is a way to waterproof that thing
I wish my problems were ever as simple as just replacing a part. Right now my engine dies when I try to use the horn, turn on the lights or click the high beam selection on the blinker lever, but runs just fine if i don't use any of those things, so it's a mystery what's causing it, bad ground maybe somewhere in the miles of wires.
I was about to purchase an 2008 Bullitt edition Mustang with only 56K miles till the owner told me the body module needed to be replaced...I was like what??? I think Ill pass. What a shame and shame on Ford engineering!
This is exactly what I needed!!!
Glad this helped you out
Where did you get the SJB from and did you have to get it reprogrammed?
@@BbbBbb-ow3pw did you find one and of so where at?
Brian West....I found one in Slidell, La and paid only $75. This lady had been rear ended and was parting out her 08. It fit without having to be reprogrammed. Ran beautiful until I sold it 3 months ago and bought a 2010 Mustang.
I was getting the error code P0463 on my 09 Mustang Bullitt. After replacing both fuel pumps (passenger and driver side), I took it into the dealership. $700 for them to tell me the issue is this Smart Junction Box. Would be $1600 for them to replace the junction box. Gonna do it myself.
Did you ever replace it? I have the same code on my 09 but haven't had any issues.
@@ZachMan99 yes, got one of the exact the same model off of ebay for about $200. Wiped my computer by disconnecting battery and alligator clipping the neg and pos together. Works great. I hear you can get it programmed for about $100, but mine works well as is. Good luck with yours- cost me about $2k after replacing both pumps and getting the issue evaluated at dealership. Would've been another $1600 for them to handle replacing the Smart Junction Box.
@@kickballjedi what kind of symptoms did you have? From researching that code it seems the only problem you can have is your fuel gauge is inaccurate or doesn't work at all. Mine is a little wonky sometimes but it's still accurate, within a quarter of a tank anyway.
@@ZachMan99 wasn't too bad, the fuel gauge would show 1/2 full at most then drop to empty within a few minutes after the car started. Unfortunately it also tripped the check engine light so I couldn't get my emissions done. Could've lived with it without the CEL. Other than the gauge and the CEL, it ran fine.
This is very useful info I appreciate the help and you definitely earned a sub and a like from me.
So I just bought a new bcm off eBay, same p/n number as the one I have on mine. I wont have to get it re-programmed it and I can just install it myself?
Good informative video Dany. My issue is my car cranks and starts as soon as the key is in accessory mode on 08 mustang. Do you think that could be an issue also caused by that BCM fuse box. Thank you for your input
I don't want to say it is the fuse box for sure, but if this started happening after a water leakage (if there was one) and the fuse box did get water damaged then it's possible, but hard to say for sure without further diagnostics, other possibility could be the ignition switch just went bad, I would say take it to a locksmith or shop that can diagnose your ignition switch, you might just have a bad switch there. apart from that, I can't say for sure that the fuse box is the one behind the problem. (but still a possibility, maybe just a fuse blew out in that fuse box)
Hopefully this helps a bit.
Thank you for this video. Did you have to re-program your key fob after the new sjb install or nothing at all?
Not at all, just installed it and I acted like nothing happened :)
Well im back , lol car has been sitting for damn near 2 years because i hit a ditch and ripped off the front and rear bumpers. Busted the radatior and condensor ... replaced all of that and am set to get it painted this coming week, charged the battery up all power comes on but now im getting check charging system , fuel level low , ect . Car wont even turn over ... 😢 helpppp
So were having issues with a 2007 mustang gt 4.6l the car runs like a champ but the moment u engage lights or ac it instantly shuts off. I know the car had a blown bulb and now the turn signals are acting up. They used to flash in succession now the fronts wont flash at all and the back only two flash together. If the weather holds today im going to take this box off and see what condition it in. Sometimes the pins corrode so much the pins break off.
poemranger did you find what it was ? Im having the same problem front turn signal dont work neither the rear only one side works
I have the exact same problem ! I just left the dealership they are trying to charge me $1200. Was ypu part a refurbished part or a new one? And where did you find the part at I need one too?
I got mines off of eBay at around $120 USD refurbished. I searched up the part along with the part number that the OEM has on it. (Example: Part number for my box was 4R3T-14B476-BS. luckily for me, I didn't need it reprogramed)
Good video, I think this is probably my issue. Does it have to be programmed in anyway or is it just a drop in replace?
As far as my experiences, I haven't had to get them reprogram. BUT I would assume you'll have to if you buy a brand new one. Hope that helps
Sweet I think I’m going to change it
Sir, While Replacing BCM need to remove battery Negative Wire??
Mine hella leaked from that spot yesterday and fried mine I’m gonna have to do this
Sweet primo! I need to replace mine but im not sure if i have to reprogram a used one? I noticed that the part number on mine ends with a bd letters do i have to match that? Also does the anti theft still works after rwplacing without reprogram and will the instrument cluster display the same mileage?
yes, sadly you will have to have it reprogrammed if you want all the original features the OEM one had before, i'm not sure how much they charge tho, depends on where you go too
@@dany5.084 so i ordered one on ebay with the same exact part number used ofcourae and plugged it in and the car started and all the functions were just like before. After about ten days however my car started doing the same exact thing. At night when i got in the car the radio console was lit up and i knew that i still had the issue. As soon as i started the car like before the dash started throwing low tire pressure, brake on, low oil, ect ect just like before!! How could another sjb do the same thing? Is my problem.something else?
@@exile9237 My best guess would be either, 1) the one you ordered was a defective one, or 2) maybe the wiring inside the vehicle itself might have gotten too badly damaged from water, at that point I would recommend having an electrician look at the wiring, maybe a fuse inside the SJB blew out or a few or relay inside the main fuse box went out, that can also be a possibility. Hope that helps, and hope your problem gets fixed asap
Bro, what can I do to fix that problem? I replaced my junction box because they had corrosion and I bought a new one and with the new one I am getting power on everything in my car but the only thing I’m not getting power on it’s my car, my radio and my windows, but everything else works. What do I do?
My radio won’t turn on and the fuse inside the car for the window pops every time I put a new one in think this could be why?
Have you ever had any water leaking through the passenger side before? If so, there is a chance that could be why, maybe not recently but if it did get a leakage sometime this year, it might be getting effected now, if you have, i might consider looking into that fuse and check for any corrosion
Do you know where I can find a SJB with kit # 5R3T-15604-DE? I need a new one and Ford no longer sells this part
Good lookin G
Does fuse # 67 in fuse box under hood power this unit ? Got a power drain in car that comes and goes.
I just replaced mine and put it back together using Dielectric grease (lizard snot) on the plugs it'll keep the water out of the plugs gunna see how it goes.
Let me know if it works great, I can probably try using that for mines next
Well its working so far.
@@dany5.084 so far ive been driving through all the heavy storms we've been getting in florida and no problems even had water on the floor of the passenger side, and the box is just fine I'd think the grease is doing the trick nicely.
I lost all my gauges.. and i cant get them to work. Fuse is good.
Does this give you issues with shifting ?
Here is the part number for a 2007 mustang gt. 7R3Z-15604-E.
Note: this part is actually called a FORD ANTI THEFT MODULE not a smart junction box or an interior fuse box.
Would the 2007 anti theft module work on a 2005?
Same here, I would like to know if the one for a 2007 would work on a 2005 mustang gt.
So I have a 05 mustang, I had the issue you said that the radio would not turn off(it is all corroded).I am having trouble reading obd2 codes…(says it wont connect) will this fix that issue most likely? Awesome video!
I can't promise it will fix it, but there's a high chance that it will. has your passenger side ever get water damaged in the past? If so it may have made it's way to the box and damaged it like in my case. Luckily a used box should run you around $120 USD (on eBay) so its not too expensive I would say, but from what you are saying, I believe the box may have gotten damage some time ago or recently and it's just now showing symptoms of it going out
@@dany5.084 Awesome. I ended up attempting to clean out the corrosion, remove aftermarket stereo, and many other things that I could find on the internet. Going to try to just purchase a completely new one. Thanks for the advice!
@@snyder6103did replacing it fix your problems? Especially the one with not being able to connect code readers?
@@3VAvenue No, it didn’t. I tried legit everything and eventually just got rid of it and bought a different S197.
I’m having a problem. It rained torrentially here and my passenger floor was soaked. I went to replace the battery since it was three years old and when I replaced the battery my radio no longer works. I can’t remember if it worked before I replaced the battery, I replaced the fuses for the radio and nothing. The stupid CD player still does it’s incessant clicking but no power on the display, no radio. All I can figure now is this box got wet and ruined it. However everything works fine, it’s ONLY the radio. I’m pretty mad but I don’t know if the sjb needs replaced or the radio. I’d prefer a new part but can only see used ones so far.
Yea the SJB box is a deliciated part of the electrical system, there's a chance it is that part since I had similar problems in the past like that too, sometimes when that box get's damaged, everyone will experience different issues since that box controls multiple interior components, sometimes it'll just affect a few features (in your case just the stereo) and in some cases (like me) where everything inside wasn't working (and I had it in the past where everything stayed on 24/7) your best bet is replacing that part or seeing if you can borrow one from a friend just to see if that fixes it, if it does than it's guaranteed the SJB box, best of luck
The lights would go off if I held in my clutch and I wouldn’t be able to open the trunk or lock the car
Anyone know where the antennae that communicates with key fob and tpms system is located in or on the smart junction box?
So you don't need to re/program this SJB? My v6 mustang is just the base with power windows and locks. My tach, speedo and temp guage works, but the A/c, fuel guage don't. A bunch of service lights came on too.
from what I have experienced, no it doesn't need to be reprogrammed for the majorities of functions to work again, my stang is also a V6 base model and everything is working fine without it being reprogrammed

DO YOU NEED TO GET INFO OF THE OLD BCM BEFORE REPLACE IT..?? DON,T YOU NEED A SPECIAL FORD SOFTWARE TO CHANGE AND UPDATE THE BCM..??
I believe it all really depends on whether you get it used or new. I've replaced the same part twice on this car and both times I just installed them and that was that. However both times I got this part used off of eBay. Only thing I put noticed to was the serial number and Ford's part # on the boxes to match the original box. I am not certain whether or not you need special programming if you go with a new unit, but I can tell you based on my experience I did NOT need to reprogram the used ones I have bought in the past
Does the BCM has to be reprogrammed? Long ago I got uno from a wrecking yard for a 2002 dodge caravan and just swapped it and worked but I’m not sure about fords.
Not necessarily, This was the second time I purchased a used one of eBay and both times I just swapped them out without the need of programming, so you should be good if it's a used unit.
Hi!
Someone knows what the different between 4R3T-14B476-BD and 4R3T-14B476-BS?
Thx!
Hello if I buy one used would I have to get it reprogrammed? An would gt an v6 be the same
If you buy it used it isn't necessary to get it reprogrammed, however... your stang will no longer have the working flashers when unlocking or locking the vehicle and/or small little features the car will have. If you want everything to work the same as factory you will have to get it reprogrammed.
as for GT and V6 compatibility it'll work, what I recommend is making sure the part # or serial # are the same on the box itself, match the number with your current one with the one you are buying. Hope that helps! :)
@@dany5.084 Thank for the info great explanation great vid
Did anyone have to get the Bcm programmed after they installed it by the dealer
Can I pull one of these off any used mustang and swap them?
Best to match the part number of your existing SJB - but be aware that a reised part number might apply. Call a dealership with your VIN and ask what the original and current part number would be for your SJB.
Do you have the original key??
If you're asking about the actual car key yes, the key is still the original key, the key fob on the other hand is not
Hey hope you’re good mine seems to have the same problem but is there anyway to fix it instead of replacing?
I'm certain you can take it somewhere where they fix electronical modules and possibly get that fixed, but tbh as far as I am aware, once those boxes goes bad, it's done. Since it is a very dedicated peace of equipment it can be difficult to get repaired.. Hope that helps
@@dany5.084 thank you man and did it need any type of programming after installation?
@@mfaisal007 From my knowledge and experiences, no you do not need it program after installation, you do however need programing if its brand new out the box, will have to take it to the dealership to get it properly program, other than that both times I had replaced mines didn't required programing so saved a lot of money there
I have the same problem as you after a flood event. Changed the fuse box and the car works fine now. except, mine is a convertible and the convertible top is not going down or up after the change of passenger side fuse box. Do you know how to fix this ?
Unfortunately not for a convertible, I have never owned one so I'm not certain if that fuse box also controls that or if it's something else. I'm sorry
The coupe and convertible have different fuse boxes. You might have bought a coupe box. You need to change it to a concert box
Does this work for 2010
Look I’ve got a 04 mustang anniversary I came out to get in my car and cranked it up the car wouldn’t go into gear ,the radio wouldn’t work,the power locks wouldn’t work And the interior lights were not working properly what do I need to do to fix the problem
Hey can you please help me please
Sorry to hear you are having issues with your stang, unfortunately I can not tell you how to fix your issue since I am not a certified technician, I can however try and help you figure the problem out but can't promise I will. So starting off... If that generation mustang has a similar fuse box in the interior I would suggest removing that fuse box and checking for any water damage (Corrosion, signs of water build up, connections rusting, etc.) If you do see signs of water damage try cleaning them using a electrical cleaner like the QD Cleaner from CRC (Can buy that at your local autoparts store) Have you have any water leaking inside your stang? Signs of water in your carpets and such?
I have a 2017 ford explorer with a short to ground could that happen on the bcm?...
Assuming they area also equipped with one similar to the mustangs 05-09 then I would definitely look into it and physically look at the unit for any signs of water damage
Question, was you getting a power drain ??? Mine started with the windshield wipers not working then working when I didn't want them to. Ended up replacing the motor and found it sitting in a small puddle of water . Ever since then I can't keep a charge . Changed the alternator and replaced the battery and it still dies within 4 hours of sitting. I contacted the dealer about a diagnosed they're all booked until November-December. Never had an issue with the windows or radio. When the car is running it runs good but I have to jump it every time I let it sit a few hours .
When I had this issue I was getting power drained due to the SJB box getting water damaged because everything stayed in the "ON" potion at all times. once I replaced that Fuse Box everything was back to normal. Unfortunately I cannot promise that will be your fix as well but the symptoms sounds very similar to what I have experienced. Have you seen or had any water in the passenger side floor? for some reason these Gen mustangs are common with water leakage going all along the passenger side causing water damage to some electrical wiring more commonly on the SJB box
@@dany5.084 I have noticed I can take the key out and open the door and the radio stayed on . I think I got the same problems but wanna make sure before I buy that shit lol it's 300 dollars right now
@@Jfizzle813 Oh it's gotten expensive lol, I would suggest going with a diagnostic first if you're unsure about anything before buying anything especially when it's expensive haha, other than that I wish you good luck on fixing your problem
My dome lights don’t turn off. How do I fix that issue. I have had water get in my SJB
If you had water previously get into your SJB then it most likely got damaged, but by the sound of it, it didn't get fully damaged, only partially since only the dome lights got affected, there's a chance that maybe one of the fuses inside the SJB got burned out or short circuited, check all fuses in the box, if it seems like all of them are good then most likely the box itself has gone bad from water damage
My key fob doesnt respond tried buying new ones and reprogramming it! No respond either 🤷🏻♂️ do you think this module have something do to with it?
theres a chance it could be, most of the time depending on year of vehicle, that module controls everything electrical related in the interior
Could this be my problem? I can shift the shifter, but radio and power windows cut off while driving, sometimes it comes back, but then it shuts off again... while it's off, I can't control the night light switch and stuff... I have tl re start my car.. can this box be the problem?
I wouldn't be able to say 100% that it is the box but since you are having electrical problems I would say check the box first for any signs of water damage/corrosion on the prongs, also if you have any water leakage running through the passenger side
@@dany5.084 that was the issue.. took it off and it was corroded... cleaned it and now I have 0 issues
Do I have to program or something like something to make it work?
Most likely, I got mines used on 2 different occasions and I didn't have to have it programmed, However I had friends where they either got it used or new and needed it program, so really it just all depends on the vehicle if it accepts the part as is or not
Did you have to have any additional programming done by the dealer?
No, luckily when I bought it used, there was no need for it to be programmed, but if you get it new then yes you will have to have your Junction box program and it could be pricey
where did you buy your modules? i am looking for a used one so i dont need programming. i have a 2007 GT premium coupe
I bought mines used of off ebay for about $120 USD
@@dany5.084 I have good news. I found the exact model from a car exactly like mine the other day. It was titled weird so it was hard to find. But it should be here next week. I'm super excited
Thank you Dany for the informative video. I have the same issue (water leakage, battery drained). I replaced alternator twice and still have issue. Do you have a video or steps to stop the leak on the passenger side? Also, what model stereo do you have installed. Need to replace mine as well and it looked cool! Thx!
Thank so much for stopping by and im glad most of this was helpful to you.
Unfortunately I do not have a video on how to stop the water leakage, that's because I haven't found a work around for that issue, all I do for now is just continuously unclogging the drainage on the passenger side every 4 months or so to help prevent water build up but no permanent solution to stop it from leaking, once I find a solution i'll most likely upload a video on that.
For the stereo I have the Pioneer AVIC-5000Nex with Navigation, you can find it online for about $500 or less depending where you search. (luckily its that low of price, when I got it this thing costed me like $900 brand new lol)
Hope that can answer some of your questions :)
You can pull the covers by the windshield wipers there's a plug in there I drilled bigger holes so it drains

Hey man does this need dealer programming? Is the programming just for the fobs?
i do exactly as what u do but now i have key fob remote issu
not work any more
can u till me whats the problem
Assuming you only replaced it. There's a chance you might have to have it properly reprogrammed again for the key fob to work. Unfortunately I can not say how much that'll be since pricing varies depending where you go and/or who does it
@@dany5.084 thnx bro
I have an 08 mustang doing the same.
Can I take another 08 mustang sjb and install without having to reprogram it?
That's what I did and it worked just fine for me, but I would double check the pins on the other SJB to make sure it isnt corroded or physically damaged
@@dany5.084 good to know! Thanks man!
Don’t know if you still respond but my 2005 mustang I just got had leaks before I got it and my blower motor won’t come on ,my power mirrors don’t work, and my windshield wipers won’t work either do you think this is the problem
Sounds like it can be that same SJB box, the one I showed in the video. That box controls most of the electronics, in my case the windows didnt work, mirros, interior lights and shifter locked up. Replacing the SJB fixed my issue, but i bought it used (~$110 on ebay compared to $400 from dealership) that would be your best bet, especially since you did mention water leak, most likely box got water damaged. Hope that helps
@@dany5.084 thanks man I’ll look into it
Hi! I know this is a really old video, but I have a quick question. I have the 08 mustang v6 convertible. I was told a certain number on the junction box barcode has to match otherwise you have to get it reprogrammed at the dealership. Is that true?
I cannot confirm if this is true or not, I can however say the 2 times I had to replace this part I always made sure the part # matched exactly on both occasions. I just installed and they where working fine without programming, I did however lost that little feature when you lock/unlock the vehicle the flashers flash to indicate you locked/unlocked the car but im OK with that since everything else seems to works how it should (This was with used boxes from Ebay, can't say if it applies to brand new ones) hope this information helps
it has to match completely or just the letter??
my passenger side window doesn't roll down would that be the cause of it not working? I have checked fuses and wiring from the switch to motor etc... my motor does get power but I cannot figure out why it is not working at this point this is the last thing I am thinking of someone help me, please
This is actually quite difficult to say, If everything is working for you apart from your window not working, it could just be that the window motor or regulator might have gone out, does your window not go down even if you try to roll it down using the passenger window switch? if the passanger window switch works then most likely the master window switch went out as well.
If everything in your vehicle (Electrical related) and if you had a water leak in the passanger side then most likely you will need to replace that fuse box, but I would definitely consult an electrician before hand, that way you dont buy unnecessary parts. Hope that helps
What if my hazard lights keep turning on? Should replacing the junction box solve that issue?
I would look more into that, I would suggest checking your fuses/relays in the engine bay first, most likely one of those went or is going out, if everything there looks like it works and if you have a way to test them and confirm they are working then move on to the junction box, I can't guarantee that the box is whats causing it, but I would say go cheap route first by checking your other relays/fuses :)
Thank you!
So the car will start even if the sjb is damaged?
It all depends, in some cases (for me) the car did start but I was unable to shift through the gears so I couldn't go anywhere (in the video the battery drained) but in some cases the car will start up and run no problem
hope that helps
Would this have anything to do with the ac or heater not working blower motor as well
That sounds like It may be a problem on it's own. I recommend checking just the fuse that powers the climate control which is fuse #15 (10amp) fuse, You should have a diagram within the fuse cover if not you can pull the diagram up on google. if the fuse is fine then it may be a fuse in the engine bay that blown up or it may be something more serious but I can't tell you for sure. You might be lucky enough to just have to replace that 10amp fuse
I have this same problem. Let me know if you find the issue
Recently my smart junction box started acting up on my 05 mustang gt convertible so i went to the local scarp yard and all i could find is a 05 mustang hard top so I took the smart box out of there and put it in mine and everything works except the convertible and my remote lock/unlock is there anyway around this or do I need to bring it to the ford dealership and buy a new one?
As far as I am aware, there's no need to buy a brand new one, especially from the dealer, from what I know, you can just take it to them, or a mechanic that knows how to, but you can just get the Smart Box programmed so everything can work just like the factory one did
@@dany5.084 That's great news man, I'm going to give ford a call tomorrow and see if its possible. I've had nothing but bad luck with this thing, I've been trying to repair it because I just dont have the 500 to dish out for a new one. Hopefully ford could do it. Thanks for the advice man!
@@YoungSaint45 No problem, hopefully everything turns out for the best for you soon.
I have the same problem on a 2010 Ford Escape, do I need to program the new module?
sorry, I wouldn't be able to tell you for sure, although if it's the same concept as the module in this video, no it's not necessary to program it (From my understanding) unless you want everything in the car to work like it was from factory (Example: Lights flash when locking/unlocking, honking when locking, automatic headlights working etc)
@@dany5.084 Thanks mate
@@dany5.084 Found this on Ebay ''Pulled from 2010 Mercury mariner drivers side airbag was deployed might need to be reprogrammed'' this is from a fuse box that I need.
Few months ago washed my car in the drive in wash and water got in and started leaking under my glove box soo now when I turn the key my headlights stay on! Also can’t lock doors/trunk with fob other then that my car was fine lol Soo what should I do
I can't say for sure but if it started happening after the water leakage then its almost certain that it could be the same SJB that fried out because my headlights/tail lights werent able to turn on and same with locking/unlocking, i had to do that manually. basically from my knowledge, that box controls the majority of the electronics like radio, headlights, windows, doors, dome lights, etc
Dany 5.0 yeah just minor issues I had was the headlights and locking doors but other then that my car drives smoothly I’ll look into it
Did you have to reprogram the sjb?
I was reading on the internet that it was necessary
If you get it brand new, yes. However, if you get it used like I did, reprograming wasn't necessary but it is optional. reason why I say optional is because little features like the hazard lights no longer flash when locking/unlocking the car things like that don't work no more. but that's something that doesn't bother me. Everything else that should be working works how it should so that's more than enough for me lol
@@dany5.084 does your car have the passive alarm or the active alarm? I have heard if it is a passive alarm then you need to get it programmed so it matches the coding of the keys.
@@marvinblaskowski9942 Mines is the active alarm, I didn't know that was a thing tbh. I'll have to do some research on that
@@dany5.084 thanks for getting back to me. My car sometimes won't crank, everything else seems to work except odd warning lights and I get dashes on the odometer, no miles, only when not starting. Car did have lots of leaks. I think it's SJB related. Good video.
Dont you need to program it first
Hey dany! I need your help please! Im having the same problem its a nightmare, does it need programming?
An electrician is charging me $200 for the BCM and 400 for the programming and checking the wires!
Please asap
no it's not recommended to have this box reprogrammed, the only reason why you would need it reprogram is for minor functions for ex. lights flashing when you lock/unlock your car, something else i noticed was that it now honks twice when you lock it but that doesn't bothers me, and this is a simple replacement, no need to pay alot for an electrician to do it, if you are comfortable enough to do it yourself, I say just get the part and replace it yourself, that is, if you are sure that your problem is in fact the SJB
Dany 5.0 ey so if i just order one from ebay should it be ready just to swap it for the old one ? I thought u need it to reprogrammed it to the ecu
Try this as well as what this vid shows. ruclips.net/video/BTAPevyl9Rg/видео.html
Where did you buy the part?
I bought it on eBay for about $115 USD, just searched up "Smart Junction Box for 05-06 Mustang"
Does it have to be reprogrammed once installed.
If you get it new yes, if you get it used theres a high chance you don't need to
I wish, I would have just gotten it use, I purchased a new sjb for 671 at the dealership for my 06 gt, would have saved a few hundred bucks
My car is shutting off when I turn my headlights on or turn signal or hazard. Would this also be the problem. Everything else works it just happened out of the blue. My car starts and runs unless I turn on the lights or turn signals
From my knowledge and experience, I believe it could be something else and not the interior fuse box, have you had any water leakage issues on the passenger side?
Dany 5.0 yeah. When I picked up the car from my mom the passenger side was wet but wasn’t really having any other issues with anything else. The car was driving just fine and then I went to park the car in the morning and the engine completely shut off. The car still had power to everything. But when I turn the headlights on the car acts like I just turned the ignition switch on however the ignition switch is already on.
I picked the car up about a month ago.
@@timothyannis3307 I don't want to promise that it could be the fuse box, but it might if it has/had a water leakage, what i would do before you go buying another fuse box, remove the old fuse box and check the prongs on every connection and check for any corrosion from water damage, if it doesn't look really clean (like the one in the video) then 70% chance its the fuse box, But I can't tell you for sure
Dany 5.0 so it turned out to be ground 101 which was on the radiator support frame rail in the front of the engine bay. Took it off and cleaned the bolt and bolt hole and then scraped some paint off and now it works just fine.
So if I buy the box from a v6 mustang or so...would it still be able to go into the gt?
it should, when I purchased mine, I didnt put attention if it was a V6 or V8 model, I just made sure the part number matched and it worked 2 times for me (I've gone through this issue twice already lol)
It will not working . Make sure you get vehicle specific sjb . GT or V6 and coupe or CNVT
Whats the part called
It has various names, most common ones are "Anti-Theft Fuse box" "Smart Junction Box" or just the "Interior Fuse Box"
Did u have one tail light now work?
In my 2 cases that I had, one situation I had my lights on 24/7 and the other situation it didn't let me turn on the lights at all, but not just one tail light, can't say if changing the box will fix this issue, if you're only having 1 tail light not working then it could be something else and not the fuse box itself
