Glad it helps brother!

Bro these breakdown videos are gold . Thank you !
Glad it helps you brother 😊👍
Thank you so much ❤ i really been debating doing a swap but I made up my mind no one really explains the steps and you did them very well
That was very informative!! I have a 95 K1500 that im wanting to put a LS in. I will definitely have look back to these videos when i start working on it.
Wow, thank you so much for putting that out there your three part video on installing your LS really motivated me into making an install on my sons truck. Thank you so much.
Thank you for the support brother 😊👍
Sounds great with the headers! Also thank you much for all the details!
Thanks brother! hope the video helps you!
I love this video I been so scared to do one and been second guessing my self but this gives me reassurance
That's what these videos are for brother! You won't know till you try 🤷♂️😊
Thanks, I'm getting plans together for a OBS swap . These videos helped a lot
Glad they help you brother and good luck on your project!
Good stuff man. I watched and saved all three videos of the swap to my playlist for future references 🤝
thanks for the support brother 🙂👍!
Great Video
I’m going back to watch some of your other videos.
thanks for that brother!
Great vid man much help provided and details
thanks brother 😊👍
Great information, very thorough
Thanks brother!
Thank you for explaining step by step you are going to save me a lot of money when I do my swap
Happy to hear that brother! and thanks for the support!
Thank you for sharing all your knowledge I really appreciate it I have a 1990 that I want to swap with my son
Glad it helps u brother! hope ur project goes well!
Super informative video love it
I’m going to buy a 1997 obs from my coworker he owned it since 2000 he’s the 2ed owner I told him I’ll take care of the truck I will ls swap it for the power but and reliability. I will do a stock swap 5.3 from my 2005 sierra which I’ll order a new engine for since it’s a daily
Great vids. I am just starting a swap into my '88. I have a complete '02 tahoe that I plan on using the L59, 4L60 and the posi 3.73 disk brake rearend. I hope I can use the harness from the '02 to make things easier
I'm swapping my 98 so thankfully the fuel pressures are good, but I I had to drop my tank anyways to replace all the lines with AN. Your vids have been absolutely Paramount in helping me finish this build. Thank you.
Glad it helped you brother and hope you project goes great!
I really ty for the parts list! Making my life so much easier this will be first time going with a LS and this is the best video i have seen! Ty so much im sure i will watch them all again lol im about 2 weeks away from getting the project going
Glad it helps you! if you start don't stop till you finish it! and you can message me on instagram if you have any questions! sups_garage
I am in the final stages of wiring ty so much for the great videos I've watched a few times! And ur parts list was on point! I did end up doing alot more upgrades then I planned which is why I'm not done yet 2 months later lol. I also deleted neutral safety switch cause I have a 93 I have one built in the sterlering column so that worked out cause I have shifter bars vs cable. Again ty!
What intake breather is that?
Happy to hear that brother! and I didn't add the air intake to the list cuz I felt like it's over priced but was the only thing I can find that fit but here you go!

@SUPSGARAGE 249 little on high side but looks clean on the install so def ok with paying that! Ty again.
Nice 👍
He'll yeah!
Thank you
Man great video it deserves millions of likes and views !
Thanks for the support 😊👍!
I appreciate this video you saved me $1500 on engine harness was about to order bp automotive harness not sure the difference between Amazon and bp
Glad it helped you brother 😊👍!
Great informative video! Love it. I don’t see why everyone says these 95s are hard to Ls swap… seems straight forward. Only question I have is was your truck a v8 or v6? Reason being is I’m looking to Ls swap my 95 one but it’s a v6. Not that I think much is different
thanks brother! Mine was a V8 but for urs, you just need to replace your V6 clam shells to V8 clam shells (the motor mounts) and you should be good
Nice job and to the point did you have to do any cutting and all that splitting and connecting to your stock harnesses or just plug in those few plugs and grounds that you displayed in your installation videos
Thanks brother! and it's both cutting into the wires to splice into the orginal harness making sure the grounds were connected
Very detailed video, Thank you! Can you drop a link for the radiator and electric fans you used?
Thanks brother! this is the radiator I used

But I ending up having to upgrade the fans to these because the ones it came with were not strong enough

Swapping my 95 this summer bro 🫡🫡
message on Instagram if you got questions brother 😊👍 sups_garage
God gone bless you for helping his lost children lol
🤣🤣🤣 that's the first hearing that one brother!
So stupid question… you need your stock harness and computer…? I’m doing the swap rn and your videos helped me a ton!!!
I wanna say yes to keeping the orginal ECU in my case cuz I was still using some wires from it to work with my LS and I just trimmed the orginal harness, keeping only the things I needed brother and glad the video helped you 🙂👍!
Bought a step side 90’s short bed and planning on doing the swap pretty soon, I’m only confused on the wiring which seems like the hardest part of the whole swap, do you have an instagram or something to answer questions? Would really help me a lot with the swap thanks again for the informative videos you’re the man!!
Of course I do brother look up sups_garage on Instagram 😊👍
🤝You give me the confidence to do my swap in my 1996 gmc … But one question what happens with the ECU from the 5.3 engine ? I need to reprogram because they come whit the antithef sistem ?
glad to hear that brother! and I left mine plugged in cuz I didn't wanna risk the chance of something not working right but I heard u can remove it if you do do it once you know it's running and you only have to program the LS computer (remove the vats for it to run)
I plan on doing a 6.0 or 6.2 LS swap on my 96 Cheyenne but I'm lucky it's a 5 speed so there's not as much electronics
Man, thank you so much for this. 🙏. This is the only video/s that showed how to remove the engine and transmission that i found. And the details 🤌. Subscribed 👍
Glad it helped you brother! and thanks for the support 😁👍!
@@SUPSGARAGE anytime 🤝
7:06 also where did new purple and green wire come from?
the purple and green wire are from the LS harness. It's the connection that goes to the speed sensor brother
Very very good video one of the best i watched so far only thing i don't get is why you didn't use the trans plug i thought you were using the 4l60 that came in it but maybe i need to watch again
Thanks brother and I used the 4l60 that came with the LS motor not my orginal one. That's why I didn't use the plug.
@@SUPSGARAGE is it ok to use the original 4l60 as that's what's in my truck
that I don't know brother because they were different years and the 95 model has a few things ONLY the 95 had, I did not wanna risk trying to find out if I needed spacers or a certain flexplate it was just alot easier to put everything my LS came with.
@SUPSGARAGE ok thank you so much probably best just to use the whole drive train then out the Tahoe then thank you so much for the response and your video was amazing especially putting the links to everything straight up game changer for anyone trying to do a ls swap
thanks brother I'm here to help 😊👍!
Do these headers work for a 2012 5.3l ls using them on a 1997 obs k1500?
Thinking about swapping my 90 c1500 why do I need to use my old obs harness can’t I just swap the motors and use a stand alone harness?
u only need to use what u need from it brother if ur wanting ur guages to work n keep all ir grounds
Good afternoon man. Do you remember if you connected the white(86)or black(85) wire from the fan(s) relay to the green stand alone wire ?
85 is the one I connected to the green wire that comes from the LS harness brother
@@SUPSGARAGE thank you man.
How about 88-89 moonies gauges? Wil yhey work on ls swaps
that I don't know since my truck did have them
Hey man where did you get that radiator bracket @17:09? Looking for something like that.
it came with the truck brother and its been on there since the 90's so I wouldn't know where to get it from lol
Any video on wiring harness? Out of lume?
u mean the factory one brother?
Thank you for your breakdown on this swap I’m currently in the process of doin one myself. I do have a question though. Do you have a email I can contact you so I can breakdown exactly what I got?
Do you have Instagram or Facebook brother?
You happen to know if the harness you used would work and plug into the factory trans on an obs of this year? Just wanna swap the engine and not the transmission.
I wanna say yes but just don't know if the pin out is the same brother
@@SUPSGARAGE I guess I’ll find out when I get there may have to splice in my own connectors.
What about the cold air intake? What part is that from Amazon? You did not say.
I did not list them because I felt like it was over priced but was the only one I can find that would fit here you go brother

I am putting a ls3 in a 4x4 tahoe and can't find exhaust manifolds that fit do you know what works
Thanks
sorry brother I have not done one like that yet to know 😔
Did you had to rig some things for that radiator to fit? Thanks
No the radiator fit just fine brother
did you use the 1995 4L60E trasmission with the LS motor ? ?
no I used the one that came with the LS engine brother
I'm doing a ls swap to my 98 Chevy Shorty. I'm stuck on how to get my fuel gauge to work. And need some help on that
Was it working before the swap brother?
For the fuel pump do you mean from a 1996 model Silverado
Yes that is correct
Nice build. What alternator did you upgrade to. Im currently havin same issue with fans. Volts when charging are under 13 volts. Also have a link for plug wires you are using.
Thanks brother and this one was the one I used
Check out this page from Summit Racing www.summitracing.com/parts/pwm-48237
@SUPSGARAGE cool thanks for link. What about plug wires. I like the way those fit that you have. I've went through couple sets. Those look like what I need.
@gthomas5880 they came as an option to go with the headers I bought from speeding engineering
Hi there about the two wire off the coil do I connect those two with the one off my new harness together
do you mean the red and the white wire that went to the original coil on the TBI engine?
Yes
@mikeromero2776 yes the red one will go to your new harness that is labeled ignition (should be red also) and the white will go to your white one from your new harness as well brother
Ok sounds good thank you for the info.
What did you do with the unused wires from the original wire harness?
@jasonkellyfixico70 I cut them off brother but only do that once it's running and everything works!
Whats the part number for radiator with the fans? Thanks awesome video
Thanks brother! this is the radiator I used

@@SUPSGARAGE thanks man!!!!!
Do you have the part# for the oil filter lol. Thanks
@marcogutierrez7916 i do not brother but it's an oil filter from an 03 tahoe
Where did you find the adapter for the steam port off the radiator
at Oreallys brother
Hey there, about the fuel pump wire off the stand alone harness which pin on the fuel relay off the fuse block did you tap in to after all
with Standalone I did nothing with regarding the fuel pump brother I only messed with the stock fuse box from the truck I just needed a wire that has power when the key is on to power the relay from here on (I did not run power straight to the fuel pump, just the relay)
Sounds good brother I appreciate your good information
@@SUPSGARAGEwhat harnesses did u buy
@Brandon_obs_ls this one here brother but make sure you know what injectors you have other wise ur gonna have to get some adapters like I did

hey bud how did you get your factory fuel gauge to work
kept my factory computer in and just kept all the grounds brother nothing special I had to do
You have a part number to the cold air intake set up
Yes I do but I don't recommend it cause of the price but it was the only thing I found that would work lol

Question 🙋🏻♂️ik is stupid but what color was the wire that u connect to the white wire for rpm and do I need to wire both ignition and rpm ? To get the tach to work thanks
Figured it out lol
Sorry brother I missed this comment from you 😔 but I'm glad you figured it out 😊👍
Hey buddy is fuel pump MPE16008 still holding up for you ?
Yes sir!
What transmission crossmeber r did you use?
the original one that was already on my truck brother
What kit for the fuel sistem did u use
This one here brother

Do you have a part number for the fuel filter and fuel pump ?
Here you go brother filter is 33481 and fuel pump is MPE16008
Thank you
So for the fuel pump did you just run a jumper wire from Pink to the green wire? Also the wires from the original engine did you cut them off and tuck them back in the original harness?
yes to both of your questions brother
Sweet thank you getting this 6.0 ready to go in! It's dbw do you think there's anything really different?
@my95chevy95 I would think it's just gonna b the election pedal n also if your fuel lines are returnless but that should be about it brother
Ok cool thanks again saving my life over here lol good work my friend!!!
@my95chevy95 No problem brother 😊👍
How did you make the voltage gauge to work ?
I didn't have to do anything to make that work just make sure all ur grounds are connected and it should work brother
I having problem with my swap. My abs anti lock is on. Idk how to fix that problem
lol mine has always been on even before my swap I just took the bulb out 🤣
Part 2 por favor

How did you get the spedometer to work ??? You said you did not use the speedometer wire on video (1) .. but in this videos the speedometer is working ?.?.. did you end up
Using the wire? If so to what wire on the obs .. tia!
I spliced the 2 speed sensor wires from my LS harness into my 2 wires from my orginal speed sensor harness to get the signal readings to go to my gauge as well does that make sense?
7:04 thats what you talking about?..
@@jamesmendoza7980 yes sir
When it comes to neutral safety wiring did you just plug in the original neutral safety wiring and that was it?
yep it will plug right in the 4L60E
@@SUPSGARAGE I heard some guys say that you have to splice the Ls and factory range plugs together to control engine rpm when going into gear. Did you have any issues like that?
no I didn't have to do that only thing I did spliced down there was the orginal speed sensor wires to the LS harness
@@SUPSGARAGE what about the two plugs that are on passenger side of trans? I believe one is the lockup switch white 4 prong and black two prong. Just cut those out?
@@731u.s.a5 you mean the orginal ones to the truck right?
How did u hook up the power line from the injection for fan
I used it to power up my fan relay brother when the key is on.
Ok so u hook it up to what wire on the relay
@@tremainethomas9112 message me on Instagram brother it will be easier sups_garage
Confused on your parts list which fuel lines and which transmission lines did you use ?

Sweet thanks man your videos definitely help. What about off the fuel sending unit did you replace the rubber hoses with these or leave them ?
@emtfire20 Glad they help you brother and I only replaced the fuel lines from the intake to the fuel filter. You can replace them to the sending unit with the same lines but I didn't see it was necessary
One more question I’m running an aftermarket intake with 102mm throttle. Do I need a fuel pressure regulator? And do you know how the fuel rail is ran
@emtfire20 I can't say brother cuz I never done that
Where did you run your wiring harness
this harness is suppose to run through the passenger side but i didn't wanna run it that way so i just had it come back to the driver side and left it there so none of it is going inside the truck
Thanks for that
Great video. Should have pulled the bed off it for the fuel pump.
How did u do the ac bro
you mean like what ac lines did I use?
I’m confused about how u did the electric fans
I didn't really put much info on that brother u have Instagram? message me on there sups_garage
U have the link for the radiator and fan ?
yes I do brother but I recommend upgrading the fans I have now(the link is also below) cuz the ones it came with does not pull enough air here in Texas lol

Where did you connect Speedo ?
you just need to Intergrate the two wires from the LS speed sensor harness to the obs one brother n it will work
You have video?
@user-do3mc4fr4s yes brother it's part 2 of my ls swap videos just look on my channel
How much was the swap?
If you mean just for the engine and transmission brother. It was $1300
Hey Siri excuse me I just wanted to ask you what kind of engine is it?
it's a 5.3 LM7 from a 2003 Tahoe
how much was your ls engine ? If you don’t mind
Engine and Trans I got for $1,300 but u can find them for alot cheaper mine came with computer already with vats deleted and the guy was able to show it running before he unloaded it from the back of his truck so to me $1,300 was not bad for no risk to take on the engine 😊👍
@@SUPSGARAGEhow many miles did it had ? And did you change any gaskets/seals ?
I was told it had 120,000 miles brother and I replaced every single gasket on the engine lol just to play it safe
@@SUPSGARAGE yup, better safe than sorry. Hahaha. I'm also in the dfw area. And the ones I'm finding are above 170 miles. I'm not sure if I should pull the trigger and just get one of those and replace all the gaskets.
