My friend, I want to thank you for the detailed videos showing the whole swap. Your videos are the most explained, and on top of that, you give us the parts list, 👏
Thanks for the 3 videos. Ls swap has been intimidating for me so I’ve been holding off doing. These videos just gave me the confidence I needed. Thanks so much.
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.
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.
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.
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 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
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!
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! LS Swap Cold Air Intake - Black... www.amazon.com/dp/B0842BMTZ5?ref=ppx_pop_mob_ap_share
Diggin the videos. Informative and to the point. Wish you had a full break down list and estimated cost of parts but I’ll figure it out. Only thing I’m going to do different is I want to keep my 4l80. Thanks!
@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

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
Thanks for actually posting a video explaining to every detail I’m a 95 baby about todo this swap in and extended cab 95 with my dad and this video is going to help us a lot but I was wondering if you could email me a parts list? What all you bought beside motor and truck and where if you could I’d really appreciate it anyways thanks for the awesome video it’s definitely the best tutorial video I’ve seen
@ i wasn’t hearing the in the tank fuel pump kick on so i changed it to a inline and i hear it come on but no start i have been trouble shooting it for the past 2 days no results
good detailed well explained video.. to be honest its not worth the drama,, the old 350,s can get 300hp easy and parts are cheaper now than ever before. i would have cleaned everything before putting it in,,, $25 worth of degreaser and a pressure wash and bobs your uncle/ or aunty these days. steve in Australia.
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 👍
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
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
i have everything connected but i don’t have my normal pcm and my amazon ls harness doesn’t come with neutral safety switch wires for my 1995 4l60e how or what do i do to wire the neutral safety into my harness ? I seen you plugged urs in but i didnt see u wire it in the ls harness are you just using the stock harness connected to the pcm for tht with no splicing into the ls amazon harness?
@@SUPSGARAGEi guess what I’m trying to ask is , is there a way i can wire it into my ls harness because i cannot use my original harness i don’t have the pcm or fusebox anymore so im confused how would the connectors work still …
@boofboikarti3235 oh I see what you mean not that I know of brother I don't think you need the old pcm but you would need at least the old wiring to connect to the neutral switch to tell the dash what gear your on
@SUPSGARAGE not yet since work has been taking up a lot of time, but this Saturday I should be wiring up everything and making the fuel lines and hopefully by next week when I get ecu tuned and deleted vats running, I miss driving my 94 hahaha
Hey! I jumped the Fuel pump at the fuse box like you showed and it works. Except now when I turn my headlights on it shuts the fuel pump off....? Any ideas?
Probably a stupid question but does this tutorial apply to a ‘93 also? I know “OBS” is 88-98 but what I don’t know is if there’s any major differences in them as the years went on for the LS swap.

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
@sergiocisneros9929 thanks brother and I removed the fitting that came with the new LS pan and I put the one that came from my orginal LS pan for I can just continue buying the same oil filter for 2003 Tahoe
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
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
🤝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)

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

What is the part number for radiator
Here you go brother this is the radiator I used
OzCoolingParts 3 Row Core... www.amazon.com/dp/B07Q26NXRH?ref=ppx_pop_mob_ap_share
But I ending up having to upgrade the fans to these because the ones it came with were not strong enough
American Volt Dual 12-13 Inch... www.amazon.com/dp/B0BT25TKGB?ref=ppx_pop_mob_ap_share
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 😊👍
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
Hey buddy is fuel pump MPE16008 still holding up for you ?
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?
What brand radiator and fans did you use?
yes I do brother but I recommend upgrading the fans I have now (the link is also below) because the ones it came with does not pull enough air here in Texas lol

Thanks bro! In the process of getting everything together to do my first LS swap on my 95 1500, your videos are a huge help! I’m putting a 6.0 in mine potentially with a supercharger if I can sneak it past the wife lol
@polarbear1034 lol I hear you on that! been wanting to put one too! hit me up on instagram if you got any questions along the way 🙂👍 sups_garage
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.
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
What size serpentine belt did you use
@leomartinez3033 Don't remember brother but here is the part number to the one I'm using 1105K6/6PK2805 🙂👍
@@SUPSGARAGE is that 2 different ones or just one part number
@leomartinez3033 if I remember correctly one is for oreallys and the other is fir autozone but same part

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 😔
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?
Confused on your parts list which fuel lines and which transmission lines did you use ?
I used this one for the fuel lines
EVIL ENERGY 6AN 3/8" PTFE LS Swap EFI Fuel Line Fitting Kit, E85 Nylon Braided Fuel Hose 25FT a.co/d/bo7N05w
and this one for the transmission brother
Limited-time deal: 3/8 6AN 12FT Fuel Line Hose Kit, Nylon Stainless Steel Braided Fuel Line Oil/Gas/Fuel Hose End Fitting Hose with 6PCS Swivel Fuel Hose Fitting Adapter Kit - Black a.co/d/a77IoLt
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
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
Which radiator did you go with? And did those a/c lines work good to rehook up the air?
@ss454gm yea the AC lines worked great brother and 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

@@SUPSGARAGE nice think I’m going to do the swap in my 90 obs cause it needs a motor anyways and I got a guy that does a turn key package on motors. On that upgrade alternator what you get just a factory one from a Tahoe or truck with factory electric fans?
@ss454gm I say go for it brother once it's all done u won't regret it and the alternator I bought from Summit. And I believe I bought the one with the most power because the stock alternator that came with the LS could not handle all the electric stuff on my truck
Very detailed video, Thank you! Can you drop a link for the radiator and electric fans you used?

What relay did you use for the fuel pump?
the orginal one is still be used brother I just had to give power from a different wire due to the orginal computer not knowing when the engine is running
@@SUPSGARAGE thanks for the fast response bro. Your videos have been very helpful 🙏
Hey boss so did you tap and connect both wires together? The pink wire and green (23:09). Can I just use a t tap?
@erickmartinez4406 I just added a wire to connect both pink and green wire brother and yes u can use a t tap as long as you just make those 2 wires connect hope this helps 🙂👍

Great job. Subscribed 👍🏻
Thanks for the support brother!
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
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
Do these headers work for a 2012 5.3l ls using them on a 1997 obs k1500?
Man great video it deserves millions of likes and views !
Thanks for the support 😊👍!
This is awesome! Thanks so much!
Did you have to do anything to get your fuel gauge to work? Mine doesn't seem to be working.
@danbuildz2054 Glad it helped you brother 😁👍! and yes my fuel gauge works u made sure all ur grounds from your original harness are still connected?
Aye bro what size filter did you use with the new oil pan thanks for your videos my ls swap is almost done
@sergiocisneros9929 thanks brother and I removed the fitting that came with the new LS pan and I put the one that came from my orginal LS pan for I can just continue buying the same oil filter for 2003 Tahoe
What transmission crossmeber r did you use?
the original one that was already on my truck brother
Does the stock ls oil pan clear the obs?
it will work as long as your OBS is not lowered brother
Thanks bro!
@@thatsubae Np brother 😁👍
Did you have to use a adapter and different flex plate? Building a 94 now
I did not 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 🤣
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
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 😊👍!
Can I buy a parts list from you
u need more then what's on the description brother?
@@SUPSGARAGE thank u silly me didn’t read nor pay attention
@richdogs8615 all good brother 🙂👍
Great video 👍🏾
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 😊👍!
🤝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)
