What a person have to do to learn how to do this as far as making your own harness and tuning
Watch lots of videos and research wire diagrams.Thats pretty much it. Not rocket surgery brother. 😜👍🏻
THANK YOU! Yours is the only video online that demonstrates how to make the tach work. Live saver for sure...
THANKS A WHOLE LOT. I BEEN TRYING TO FIGURE THIS OUT FOR A YEAR .THEY SELL YOU THE STUFF .BUT DONT TELL YOU HOW HOOK IT UP THE CORRECT WAY. ONCE AGAIN THANKS.
James Scott, Thanks for watching! Im glad this video helped you out! If you dont mind, share this video or the channel on some social media accounts. We're trying to grow the channel and any help would be appreciated!
Thanks! You were the first result I got when I searched for this. I have a LM4 V8 using a 4 Cylinder engine's tachometer and the Tach Output setting in HP Tuners was exactly what I needed to know.
I like knowing how stuff works, or why it don't work!
thanks for this info . got my equus tach running right 🤙
Awesome. Solved my tach issue.soldered in the diode to a 12 v feed. Works perfect now. Thanks for the info.
glad it helped brother.
Thanks brother, I am going to try to make my tach work again. Once your car has had a working tach you just miss it, and want it working again.
Awesome video! Def answers my questions I had why it wouldn’t on 8cyl mode and only 4cyl mode.
The way I see the tach output in hptuners is u have a 24x recluctor wheel. If u have 6 in Hp tuners that’s 4 cylinder tach output (24/6 = 4 same for 8 cylinder which would be 24/3= 8) it’s basically telling the pcm every 3 pulses off the crank trigger wheel a cylinder hits top dead center
You should NEVER use a t-tap or such type connector. I make a good living off fixing wiring issues because of them. Love the videos I have seen so far. Will continue to watch more.
Thanks for watching! As for the t-taps, I generally avoid using them outside of passenger compartment unless it’s temporary. Inside however, they’ve never been an issue since they’re not exposed to moisture or contaminants.
Very good video. Thank you for sharing. I've actually watched it about four times over the past few months. And, what you said makes sense. However, I'm confused by the details of my particular application. I am in the middle of an LS (LM7) swap into a Jeep Wrangler TJ. (Engine is in; I'm working on the wiring harness now.) I am struggling to understand the wiring for all the factory gauges - speed, tach, volt, temp, oil, and fuel. I will be running both the GM PCM and the Jeep PCM.
From what I understand you saying is that in order to get my electronically-controlled Jeep (6-cylinder engine) factory tach to work, I just need to insert a 1 kohm resistor inline (with 12 volt power) to the Jeep tach wire?
The problem I'm having is that both the GM and Jeep PCMs send tach and speed signal to the gauges over a serial interface (serial data for GM, CCD bus for Jeep). There is no one wire for each gauge. (I could send you pics from the service manual.) So, how do I even get the signal from the GM PCM, through the Jeep PCM, into the gauge. I am so stumped on that. It may be super easy. But, I'm not getting it.
Do you have any idea how to resolve the dilemma? Thanks!
Sorry brother, I have zero experience with Jeeps but I’m sure it’s been done before some someone on the internet has probably covered it in a Jeep or LS swap forum. I’d just grab a four pack of energy drinks and fire up the old google brother. Sorry o can’t be more help on that one. As for the tach, unless it’s ran through your BCM as well, yes the jumper mod should work. 12v ran through a resistor into your tach lead as shown in the video and you will need to change your tach signal in your tune as shown in the video as well to output a 6cyl signal.
nice I was curious of what was change to correct the output. Mine was already done for me. I am also not a fan of mail tune that's is one of the reason why I bought my own HPtuner.
yea I keep seeing people having issues so I thought if I make a video explaining it then I wont have to type out an explanation every week,lol
thanks for the video man! quick question hope you can help, I have a 95 c1500 with a ls 5.3 swap , do I need to run a signal wire from the pcm and connect it to the dash harness? I think its an obvious question , just want to make sure thanks again
Great video. We just completed a swap on an 87 rx7. The original tack signal was for a 4 cylinder. My tach is currently showing 2x what my ECM shows. Could that be because the tuner may have set it to a 3 for a V8 where he should have set it to a 6 for a 4 cylinder? What's your thought on this?
Those are called wire taps and they’re amazing
Hey bro i have a 89 foxbody 302 sbf been converted to carb my tach is reading backwards! Any ideas why?
I'm doing a DBW swap in my 98 my issue is after about 15 second of running I loose that crisp fast throttle response and then it runs like crap no codes it has not been tuned yet fuel pressure is 56psi
I put a LS in my 67 Chevy c20. The harness I made was allowing my gauge to work(intellitronix). I swapped the harness out with a stand alone and now the gauge doesn’t move at all. I got it to move about half of wired directly to negative side of one of coil packs and set of 4cly. Other settings dropped it lower. Intellitronix advised this might happen in their wiring instructions and offer a resistor but theirs is a 10k not a 1k. What are your thoughts?
My thoughts are you obviously haven’t seen my videos on intellitronix gauges and other products. They’re garbage. I’ve installed multiple sets and the ones that actually worked initially ended up glitching out and failing within a few hundred miles. If you have done everything shown in this video and still can’t get the tach to work correctly, I’d suggest sending them in for warranty and hoping they don’t take 4 months to get you a new set like I went through.
Hello . I have a honda magna vf750c 1995 rc43 I am writing to you and ask for help. I bought a honde after a light accident. From the beginning, the tachometer did not work and I really care for it to work. It was checked with electronics and everything is ok with the tachometer in the cup. Looking for the cause of the fault, I checked the entire installation and it looks like it's ok. I used electric fluid to lubricate it. The motorcycle normally starts, rides but the tachometer and ignition switch on the right side of the handlebars do not work. The switch is cut off. I turn the engine on with the ignition and starter, turn the key off. My question where is the signal from the original tachometer? I would like to connect the cable directly to the original tachometer from the spark gap or coil ?? Can I do it, where does the tachometer signal come from ?? With a tachometer in a mug, the yellow-green cable at low speed shows 13.80 volts, if I add gas, the voltages decrease. Thank you in advance for your help. best regards
my name is Craig I have a 2000 Silverado mud race truck I have been running a 5.3 with a 200 shot of nitrous I need more torque i'm putting a 632 crate motor in it with a sniper EFI 4500 running the factory 2000 dash cluster, wanting to hook the tack it can you point me in the right direction thanks in advance.
Hello there I am from Germany, not exactly understanding everything properly. Anyhow, I got all the items: Resistors shortcuts etc. Do I do the bridge between minus coil cable and plus from the ignition key or do I have to bring extra plus wire from the battery for instance.
Stay healthy
Perfect, thank you for posting this.
This is gonna help me a ton.
Love your videos.
Thanks for watching brother..glad the video was a help. You can check out the "LS SWAP TIPS AND TRICKS" playlist for more videos if you need anymore help.
@@BadLuckGarage I am working with a swapped V6. The original tune file for the V6 was set at 1 and 1 in those boxes...why? You can download a tune file from the repository and see for yourself. 2001 Chev Silverado 4.3L
Hello i have gen3 v8 swap to gen4 car i dont have a tach till now you have any idea how i wanna link it?
Hey there,
I have a ace well speedo on my Honda trx700xx I have a added the correct circumference into the settings, it works but jumps around to higher mph like 120mph 80mph etc
Any advice would be great luck
Does it have to be the 12v to the tach or any switch 12v work as well?( for resistor )
Hello I’m restoring a 77 gmc pickup. Changed the cab and want to use the original cluster out of 77 it has factory tach got it hooked up. When I turn key on the tach starts to go around. When I start the truck tach goes to the bottom. Can you please give me some advice on this problem
Has this been done with a LC80 series? I have an LS1 and it was originally a 6 cylinder petrol. So I need to get the pcm flashed to 4. I can’t work out witch wire on the 80 tach is the one to tap into. Any help would be much appreciated every one I’ve asked in Australia either doesn’t know or is tight lipped about it. Cheers 🍻
This was a great help. Do you have any info on the speedometer and PRND light 1999 tahoe with 2002 ls 6.0
I've got a different problem..I had a cheep tack on my 89 k1500 and it worked...I installed a Mallory competition tach that I had on my 68 Camaro, speed limiting and shift indicating. when I hooked it up it killed the engine...when I disconnected the green signal wire the engine would run. I reconnected the signal wire and it would arc and the engine would die like it was shorted to ground. I also noticed after I disconnected the signal wire the tach would indicate rpm but not respond to throttle. I checked the signal wire for a ground but got no indication of a ground fault between the distributor and the tack.
Any ideas?
Thank you, this helped me!
How about if it still doesn’t work? Is there a certain way to install the resister?
If you did everything in this video exactly as explained in this video and it’s still not working, then your tach itself is the problem as explained in this video.
How about Holley terminator? My tach works until u get on it and pegs out. Lights get dim in tach also.
Sounds like you’ve got a wiring/ground issue.
@@BadLuckGarage Thanks yeah wired to seat bolt to body. Going run one from engine block and see if that helps or straight to battery.
do you know how i can setup my rpm .its 89 camaro and im putting in a carbd 03 5.3 ...the msd box has an rpm wire ..im hoping i can use the stock cluster for the rpm
you can use the msd box or you can follow the instructions in this video.
Super helpful, thanks for the details. Subscribing
Thanks for watching and subscribing!👍🏻
Very good info. 👍👍👍👍
Thank you. Glad I was able to help!
Will the first fix work with a V-8 engine with distributor? Everything works on tach but doesn’t read rpm’s
This is an LS swap specific fix, hence the video title.
okay working on hooking up some gauges Tech is the one I'm mainly having the problem with watch the video here good information shouldn't be a problem for me to get the resistor pretty sure I understand how to tie the resistor in but wondering do I still need to set it on 4 cylinders with the resistor that's my only question also left side of the resistor hooks to switch 12 volt right one with brown mark on it
Hello Dustin Chesshir, Thanks for watching! Im glad this video helped you out! Just jump the resistor from the tach power wire to the tach signal wire as shown in the video. If using a factory tach then yes, jump it from a switched 12v to the tach lead.The setting you use in the pcm will depend on what the tach is set up for. If your tach is set up for a 4 cyl signal then you dont need to change anything. If its set for anything else then make the changes shown in the video.
Bad Luck Garage the tack I have is a glowshift and has a switch on the back to pick 4 6 8 or 10 cylinder so without changing anything on the PCM at the moment I don't have the HP tuners yet just install the resistor in line and set my tach to 4 cylinder correct
yes sir!👍
Bad Luck Garage appreciate it buddy I've got a resistor now I will try it tomorrow and see how it works I was kind of wanting to leave the ECM tac setting alone hopefully this doesn't change the signal inside the PCM if it does no big deal but I have a little Bluetooth OBD2 scanner and I can see the RPMs on the gauges on it through my phone kind of cool little setup only cost 75 bucks you can see other perimeters and stuff too
Got it going appreciate the info
This resistor remedy was a good idea, but didnt fix it all the way... it only makes the needle move a quarter inch from zero, even when revving high. I have a 1990 Firebird Formula tach, and want to run it off of a 2001 LS1. I need more brains on this lol. What do you think is good?
Hey brother. If you’ve already addressed all the issues in this video then either your tach is just bad, you’re not getting a good connection at the tach, or you didn’t wire it properly. Those are the only things that could be wrong. Make sure you used the correct resistor and that you wired it in correctly to step up the signal. Also make sure that you’re getting good connections in your dash at the gauge itself. I k ow I’ve had tons of issues with those older dash assemblies with corrosion or just loose connections. 👍
Need help. On my LS swap, I had wired the tach wire from the pcm to my 69 Camaro tach gauge. The problem is, the gauge seem to react slow/lagging to the engine rpm. Any idea?
If you’ve already adjusted the settings as shown in the video then it may be the tach itself that’s bad.
Bad Luck Garage it can only be those two that could be wrong. I’m not 100% sure that guy that did my harness and flash, set my tach setting on my pcm. Thanks bro
If the tach reading is lower than actual rpm bust still consistent then it’s probably set up incorrectly in the PCM. If it’s more random then it’s most likely a bad tachometer and needs the guts replaced or you need to replace the entire unit.
I cannot find the tach output on hp tunners, when I click engine and general the only thing that shows up is disable ect
You probably have it set to basic instead of advanced. Advanced mode shows more options.
@@BadLuckGarage awesome! I look into that. I’ve only changed fan temps
I have a 2007 VW Jetta tachometer stuck at 1800 RPM at all times! Any ideals
Not unless you have an LS in it as the title clearly states.
Need help with transmission on my ls swap
My tachometer reads 0when I start my truck but everything is running fine. Rpm’s are right. When I accelerate the needle moves up but reads low. Only reads when accelerating. What can I do to fix it?
ruclips.net/video/FS7aRfYkFAQ/видео.html
My oil pressure gauge isn’t working as well as my tach since the swap. However my aftermarket tach and oil pressure gauge work fine. I am going to try this for the tach, would it also work for oil pressure?
Thank you
No
It's REALLY THAT SIMPLE ??? I got one of those one size fits all Amazon Chinese stand alone harness. It has about 9 or 8 bare wires and the white wire is for the tach signal. Wired it up to my trucks tach wire and nothing.... ??? I hope this is the fix. Much thanks 😊
Yes. If none of these fixes work then it’s most likely an issue with the tach itself.
@@BadLuckGarage I tried it as soon as I got home. Still nothing on that white tach wire from my awesome eBay harness. I still have to get the truck driving we'll see
@@aldoladrondeguevara7259 Ypure not going to get anything on the white tach wire. That’s the entire point of the pull-up resistor shown in the video.
Great vid ,Question doing a LS swap on a 85 IROC would it require a 4 for the tach on HP tune
?
11:50
My tachometer reads double I have a full MSD ignition set up and bigger Holley 4 barrel carb on a 1970 396 big block Chevy. Can you tell me what’s wrong?
Well if I had to guess, I’d say the first thing that’s wrong is you’re asking for advice on a carbed big block setup on a video that’s about fuel injected LS swaps on a channel that does nothing but fuel injected LS Swaps. 🤣 Beyond that it sounds like either your MSD box isn’t putting out the correct signal or your tach isn’t set up correctly for that signal.
Hi Friend One question. I have toyota allion 240 and its tachometer working some times and some times doesn't.. if it is working its working fine according to my understanding but most of the time its not working. if you wouldn't mind please do let me know the reason for this ?
If its an intermediate issue then the most likely cause would be a loose connection or corrosion in the connection.
it would be really help full if you can made video on particular model (Allion 240) tachometer connection "how to fix it" would you be able to ???
These videos are pertaining to LS swapped vehicles.
I have a 91rs 3.1 v6 my tach goes all the way to the right when the car is running.. what can I do to get it back to normal
Probably need to replace the circuit board in it. Google “Cajun Tach Shop”. They sell replacement boards for these cars for around $50 and they’re even adjustable to calibrate for different engines if you swap out that V6 down the road.
Help plz
I put after market tach in my 2002 chevy 1500 n it's 500 rpm off
I did the 4 banger wire cut but still off ??
If you tried everything in this video and are still having problems, then the tach itself is most likely the problem.
@BadLuckGarage I not sure how to go into the soft where like ur showing what do I need to do that
I enjoy your videos
I’m having a issue with my tack
LS swap 78 Vette
Intellitronix dash
Psi harness
Thinking i need to take green tack wire in intellitronix and connect to white wire on PSI Harness
The instructions with the Intel a Tronics Dash our gear for using the factory gauges I’m thinking that I need to take the wires from the intellitronix unit and splice keyed power and ground , then connect green intellitronix wire to the white wire on the PSI harness
if you could point me in the right direction I would sure appreciate it
Watch my tach wiring video in the LS Swap Tips and Tricks playlist. But also know that I’m NOT a fan of the Intellitronix digital gauges. I’ve had tons of issues with them multiple times. Matter of fact I have videos documenting those issues in the project SteppinWolf playlist. I have no experience with their new line of analog gauges. I was actually invited to test some years ago before they even went to market by their marketing manager but refused due to the issues I had already had with their gauges and window switches.
I know this is an old video but I just saw this and I am trying to finish up my swap it's the last gauge that isn't working and I did exactly what you said but I have no response, it's a street glow gauge it turns on and the all that jazz but it does not respond I have installed a resistor in and still nothing any ideas?
If you truly did the wiring and pcm tach output settings “exactly” as I explained and it still isn’t working, then you have a bad tach. I would suggest going back and checking your work before coming to that conclusion. 👍
I have a dakota digital dash and it's not working I have installed the resistor
I just had a cam swap and my gauges are trippen. My fuel. Battery and coolant temp. Can you tell me what’s wrong??
sounds like a ground issue. If you just did a cam swap them chances are one of the grounds on your heads either isn't bolted up or didn't get tightened up or the ground strap from engine to firewall.
Can you use 0.5w resister?
I have a 598 big block. Just installed new tach / dash gauges. Tach reads proper rpm eventually but sweeps very slowly. I see your talking about setting it to 4cyl. It’s currently on 8cyl. Should I set it to 4? Is this just for LS engines ? Someone help!
Your answer is in the title of the video brother.
When you don't have Tach wire coming out from the pcm pin 10 because the truck didn't had a tachometer originally, do i need to mod something in the pcm to make it work?
thank you
Hello Taur Pillisner, Thanks for watching! Im not exactley sure what you're asking but if you dont have a wire in the pin 10 in the connector, then you will need to add one to get your tach signal.
Sorry dude, english is not my first language.
Got my engine out of a Savana van and it didn't had any tach at all.
One guy with he's Hp Tuner disabled the vats system from the pcm, thought that 4's are the correct numbers. When watching your video i realised that he put the wrong numbers there.
But the pcm has never sent out any tach signal at all. Question is that do i need to do anything else in the pcm or just putting the wire into the pin 10 will give out the signal?
Ok I understand now. You will need to put a wire in pin 10 if it’s not there. You also may need to do the 12v jumper wire trick mentioned in the video as well. Not sure what your tachometer is for but you’ll need to adjust the output to match also.
I changed my tech to 4-cylinder and put in a resistor The tech is staying close to pegged out any idea?
ruclips.net/video/FS7aRfYkFAQ/видео.htmlsi=hfaOmqpWzRqEezhv
I give it a watch thanks.
I just got a cam and stall . So I asked the tuner to look at the setting in the ecm. They said it was set correctly.
Of course I can't click on the link... Thanks though
@@thetxwildchild If you’ve done everything in this video and the tach still isn’t working correctly, then the tach is the problem.
If I had a 4 cyl 01 s10 and put 5.3 ls in it what would I put in
It has the stock gauge cluster
It reads double the rpm

Hi sir any mode to contact you for few questions oh dropp a truck to fix some issues I had
My tach not working xorrectly. When idle under 0 and max 1.5 kindly help
awesome dude thanks!
Glad you found it helpful brother. 👍
@@BadLuckGarage damn cant get my tach to work still. I tried the pullup resitor with 1k, but that didnt work. Then wired in the dakota digital adapter, and the guage worked in testing, but not while running. I checked my incoming hz from pcm and its showing 0. Is it possible that the signal is turned off in the tune some setting in the hp tuners? it shows 12 volts at pin 10, but no additional signal...
Can this be done on the trailtech vapor? Had it wrapped round spark plug lead and was poor, now have it wound round coil spade connector, it works but not too responsive and when engine is cold doesnt even register idle revs
I apologize brother but I have no idea what a trailtech vapor is or what it has to do with an ls swap. 🙄
Hello do you think the resistor will work on my 77 square body factory tach
yes
Thanks dude.
You bet!
What if there is an rpm error? My tach reads 100 rpms low at idle (reads 600, actual rpm is between 700 to 750 on HP Tuners scanner). The error increases with rpm, 2000 on tach, 2200 n HP Tuners. Will the resistor fix this, or is there some other way to correct it?
If your tachometer is off by that small of a margin then it is most likely just due to tach inaccuracy. Especially if it is a factory style tachometer. They aren’t exactly known for accuracy.
hi there im working on a projet and i just add a tach from a safari ski doo to a lawn tractor motor with 1 cylinder and only have a green wire and a yellow wire. the only way it work, i wired the green one to the killswitch wire and wired the yellow to the light wire that comes from the flywheel but my issue is the tach read 6000 rpm. ill it be the same scenario of your video. any suggestion?
thank you
no, this video has absolutely nothing to do with your scenario. As stated, this video is pertaining to tachometer issues with LS engine swaps.
I have a ls1 with intellitronix digital gauges and the tach is reading way off. Should i cut the blue wire to have set on 4 cylinder
No. You should send them back. Intellitronix makes garbage. I spent almost an entire year going back and forth with that company over thier junk. But if you insist on using them, just have the tach output signal changed in your tune as I showed in the video. If that doesn’t fix it then you’re one of the many people who got a set of crap Intellitronix gauges. Sorry.....touchy subject with me. 😒
@@BadLuckGarage ok i guess i have some crap then thanks tho
Sorry brother. Like I said it’s just a sore topic for me after everything I went through with them. Yes you can try setting it to a four cylinder signal. Both sets of Intellitronix gauges I bought seemed to work good at first but after only a few hundred miles they started having glitches and things that you can see throughout the earlier videos on this channel. Speedo started blacking out when lights were turned on, tachometer got to where it would drop to all zeros after about 3000 rpms, odometer would randomly reset. Just lots of glitches. Took me months of phone calls and emails to get them to finally honor the lifetime warrently and send me a new set then when I got them they were mismatched colors( see the Intellitronix replacement videos). During that year I had also purchased one of thier window switches to use with my nitrous setup and it also failed on video at the track. Finally after I made a video talking about my horrible experiences with both thier products and customer service, they contacted me and gave me a full refund in exchange for taking the video down because it was hurting business.
my tach only goes to 2 grand won't go no higher don't matter how fast u go???
Have an oddball swap and question for ya. 1998 Trans am shell, with a custom built 1995 3.4l v6 engine. Retaining the stock ls1 cluster I've got the tach wired so it registers, doesn't bounce around or anything. However, I feel like it's reading wrong. My idle is set in the tunerpro software to sit at 900, but the tach is reading 1900. Is it as simple as changing the tach output in the software to represent the v6 engine?
If you’re still using the Ls1 pcm then yes, you need to set the tach output to a 6cyl signal.
@@BadLuckGarage Using the original V6 pcm
If you’re using the 95 v6 pcm then I’m not sure how you would be able to change the signal other than using an external device from a company like Dakota digital. 95 pcms were obd1 and there aren’t a lot of tuning options for them. At least not mainstream Tuners like HP Tuners.
Hello, I have buyed a new tachometer for my V6 cilindar boat engine.
When I hit full trothle I get maybe 700rpm on tachometer.
Will resistor help or you have another solution ?
As the title states, this video is pertaining to the tachometer issues with swaps of Chevrolet LS series of engines. There are many things that could be causing the issue with your particular engine such as a bad ground, tach made for an engine with a different cylinder count, bad electrical connection, etc. But that is not my area of expertise. Sorry that I couldnt help more but I hope you get it figured out brother.
Hey bro i have a problem with my tech i cant get no rpm to battery light no oil light an no temperature gauge. We try everything an cant get it to work
It sounds like you have an overall wiring problem in general. Not just the tach. If you have that many gauges not working then you need to just start over and trace all your wires.
@@BadLuckGarage so i should just get a full wire harness an a new computer an just put it back in an its good to go
Brother I’m saying I have no idea what you’ve done. But I’m not saying go buy more stuff. I’m saying trace back over what you’ve done and make sure it’s correct. (Obviously it isn’t). Wiring can be a pain in the rear sometimes but if you go over everything you’ve done then I’m sure you’ll find the issue. If nothing is working, then it has to be either a power or a ground issue going to everything.
So I have a 95 camaro with a 5.3 turbo swap tach works but when I hit boost it just sky rockets to redline and no it's not the trans have you heard of this issue
Nope
Doesn't sound like a problem!
How did you integrated oem Canbus with the standalone?
I didn't. None of the vehicles I swap use canbus. I swap old hotrods. Camaros, Novas, C10s, etc.
Will the first option work if I am putting an LM7 with an fbody pcm and harness into my 350z?
I believe everything in the 350z works off a BCM and CANBUS so you may need an interface to get everything working properly. Give Ryan over on the A21bravo RUclips channel a shout. He’s currently dealing with that setup and cm probably help you out more than I can with 350z related specifics. 👍🏻

Great video. I was looking for something about the signals!
Hello Anthony Griffin, Thanks for watching! Im glad this video helped you out!
Great explanation! Really appreciate your time and knowledge and for giving this information out to us. Your a great kind man👍 🫡
My pcm don’t have the option to change tach Signal
ALL LS pcms have the option to change tach output.
Bad Luck Garage What if I change it externally with a Dakota digital tachometer calibrator running it from the PCM to the tachometer
Make sense, no, Good! Lol
Lol!
Will watching these videos give me bad luck ???
Probably 🤣
Bad Luck Garage wow lol I was just messing around not expecting a reply 😂😂 the videos helped a lot thanks 👍🏻
Lol, glad they’re helping you out brother. Keep that penny and rabbits foot in your pocket though. 😉
tach goes to crank sensor check it first! when swaping motors they need relearned with tech 2 tool!
