LS Swap Wiring Made Simple!

In this video of hooking up an LS swap harness again. I hopefully do a better job at explaining how to hook up the wiring harness on your gen 3 LS based engine. DON'T LET THE WIRES SCARE YOU.

Most thorough and simple video I've watched. Thanks.

[@stephenhodge6441]

Yes on the brake switch video!

[@adamcaballero8538]

Thank you for sharing all your knowledge on LS swaps and yes the brake switch video would be awesome

[@jemelmonger]

Shout out to you bro ! This just helped me so much! I ain’t know where a few of these sensors were. Great video! I tune in often. Keep dropping bangers !

[@wadebonhomme2142]

Once again I appreciate the info, I actually saved this one!

[@texasrifleman9657]

Best one yet thank's !!!

About time I start getting your notifications!!🔥🔥🔥 FIRST!!!

Yeah Buddy

[@MsVersus]

Clear explanation, thank you!!

[@luisrodriguez-fs8pl]

I bought the same harness I’m trying to figure out how to wire an electric fan I got the72 Monte Carlo done 6.0 please help

[@72NovaLS-SP]

Brake switch a must see

[@stephenlovelace1417]

Yes brake switch video

[@hunk-n-junkcustompressedst1502]

Hey bud, thanks for the video, it helps a lot... What about the gages? Going from the electronic stuff to the old school gages like the speedo, and stuff?

[@TriStarGearhead]

Gauges should be on your body harness with a car. The old school gauges have their own discrete sending units which you can usually get adapters for.

[@krustyclassicsgarage]

You can either run cheap digital gauges on a tablet (I have a video on it), Run Dakota digital gauges, or use adapters to adapt your factory gauges to the engine

[@lupitavences499]

So what do I keep on my stock truck harness from a 94 Silverado or do I not need none of it?? And if I do how do I go about wiring it up thanks

[@Dad-jk2wd]

Thank you!!

[@raynaldolopez3780]

whats a good price for a complete 6.0ls ? I wanna swap my 97 obs chevy.

[@CharmleysChopShop]

What app did you say you run for the gauges with the Bluetooth obd2 reader?

[@Woppy323]

Can you make a video on the fuse box and how to wire it so it starts with key

[@kingloc1008]

Any quick connects for gen 3

[@CharmleysChopShop]

Have you run into transmission code issues? Mines pulling a p0785 3-2 shift solenoid code, I've heard people having issues with pins being in the wrong spot.

[@lynnwilliams4235]

Yes make a video

[@lsxeddie]

Please make a step to step video bro we tryna be like you!!!!

[@krustyclassicsgarage]

I'll try to do it the next LS swap I do. I have a step by step in the videos of the last camaro I did.

[@user-tl4hn2ps6t]

Yes please. I swapped my 72 nova with 5.3 4l80 with help with your videos and now I'm on the harness part 👍🏻

[@lsxeddie]

@@krustyclassicsgarage im doing a lq4 swap on my v6 obs rn bro hopefully itll turn on with this next video! Im sure the wiring colors are the same on most chevys?

[@user-ku4po3nr4v]

Do you have to tune when putting a ls1 I intake on a truck 5.3

[@krustyclassicsgarage]

No

[@danielcastaneda5249]

So I would need a drive by cable computer if I’m running drive by cable TB?

[@krustyclassicsgarage]

Yup

[@johnthurmanmerman]

What were the rest of the wires in that bundle with the brake switch for? How are gauges hooked up? I know you run a tablet but if you wanted to make all of the old mechanical gauges work would that be possible

[@krustyclassicsgarage]

You'd run adapters to the engine and hook up your existing gauges to thos adapters.

[@johnthurmanmerman]

@@krustyclassicsgarage where the rest of the wires in that bundle with the purple brake switch not needed?

[@krustyclassicsgarage]

@johnthurmanmerman not to get the engine running no. They're extra things like tach, TCC, cruise control, etc. I'd have to look at the instructions to see what every wire is for.

[@chadgardee1496]

I think the cam and the map is more likely too get switched happened too me and I done a lot of these swaps

[@Q..08]

What brand fuel injectors do you use with that harness ?

[@krustyclassicsgarage]

All of the cheap gen 3 harnesses are set up for ev1 injectors.

[@prnd21turbo]

The Ls I bought has the complete wiring harness still attached to the engine. In your opinion, is it easier to sorta make the original work ? It’s going into a 65 C10. Old shit.

[@krustyclassicsgarage]

What year engine?

[@prnd21turbo]

@@krustyclassicsgarage 2011 Ls out of a Camaro. Thanks for responding Man .

[@krustyclassicsgarage]

@@prnd21turbo Thats a gen 4 so you'll have to get a more expensive harness as this video shows a gen 3 harness. I would look at BP Automotive harnesses.

[@Fath3rAndSonFitn3ss]

Will this apply to newer LT engines?(LT4)

[@krustyclassicsgarage]

Nope. Completely different engine. Stay away from them if you're new to all of this lol

[@rickystunts]

Is there a knock sensor plug?

[@krustyclassicsgarage]

Yes. In the middle of the loom, where the big split is between the passenger side plugs and driver side plugs. Sorry, I forgot about that plug.

[@luisrodriguez-fs8pl]

gotta question i bought that harness and it dont have a knock sensor plug do the sensors get elimated

[@krustyclassicsgarage]

It has it, it's next to the cam sensor plug if it's a Gen 3 harness.

[@luisrodriguez-fs8pl]

I found it lol

[@_Greasyzoku_]

Hey my tuner said I can run my DBW ecu on my DBC setup. He will set it up. But I bought the DBC wire harness, will I be ok?

[@krustyclassicsgarage]

Yes. As long as your ecu is set up for dbc

[@_Greasyzoku_]

@@krustyclassicsgarage whew! Thanks bro! I think you’ll dig my 64 Tempest. When I get it going I’ll post it with a burnout or something

[@CharmleysChopShop]

Are you able to run a cable throttle body with a dbw PCM? and just get it vat deleted and programmed?

[@krustyclassicsgarage]

No. Ecu has to be set up for dbc as it has different sensors on the throttle body specific for dbc

[@artm700_]

@@krustyclassicsgarage I got a drive by wire harness, ecu, and intake, I really want the drive by cable what do you suggest I do? Do I have to get all new harness, computer and intake? Or should I just run with the drive by wire….

[@krustyclassicsgarage]

@artm700_ dbc is much more simple for a swap. You need dbc throttle body, dbc harness, and either have the dbw ecm tuned to a dbc ecm or just get a dbc ecm

[@artm700_]

@@krustyclassicsgarage appreciate the quick response brother, and yea so I’ve heard it’s my first ls swap so I really want the dbc setup, thank you man I’m gonna look into getting a new throttle body and harness, sweet content btw 👍

[@dariusdarrell4334]

The brakes switch video please sir

[@roadboiipluckiee6938]

Bro that China harnesses has an extra 2 plugs on them to. but I think it was killing my map sensor

[@krustyclassicsgarage]

Ya some of them do and idk why I didn't realize it with this one but I think it does. Not all of them do, it's really just the luck of the draw to get one with the extra wires. They're an IAT sensor set up. If your engine isn't running right with just the 5 pin maf then those 2 extra plugs you take and put on an adapter to a Gen 4 MAF sensor. I need to look at this harness and double check but I knew there was too many wires in the driver side bundle

[@roadboiipluckiee6938]

@@krustyclassicsgarage right 😂😂 I told them it was killing my sensors and they sent another 1 for free good ebay company I think I may be having fueling issues bc wen i try to do a burnout it will creep up hit a wall and fall on its face

[@krustyclassicsgarage]

@roadboiipluckiee6938 ya, I've had 2 of them. 1 of them I had to use an adapter that was on an 84 s10. The Vega that's on here I got one but I plugged in the 5 pin MAF and it ran perfectly so I didn't need to use the iat plug. Weird. Ya, sounds fuel related.

Break switch video Please and thank you.

[@40calfilms21]

What about oil pressure sensor

[@krustyclassicsgarage]

Doesn't use it

[@DumbCarGuy]

Just forget about the other 285 wires for now and do just one wire at a time and you will be amazed. Besides thats the only way you can do it anyways, one wire at a time.

[@stevepope5484]

Looked like maybe 2 relays? Like fuel and a second relay?

[@papergatorzfedducca7998]

Cmon with the brake video.

[@johng83]

What about the IAT ?

[@krustyclassicsgarage]

Gen 3 doesn't have that UNLESS you get one of these harnesses that do which this harness may be. Every now and then I get one. If so you run an adapter to hook up the iat sensor to the 5 pin maf sensor. I'll have to look at this specific harness and see if it has it or not but most of them don't and don't need it.
