LS Swap Wiring Made Simple! 

Yeah Buddy

🫡

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.

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

No

Yup

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

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

I found it lol

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

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

@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.

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

@@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

What year engine?

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

@@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.

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

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.

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.

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

@@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?

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

@@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….

@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

@@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 👍

Doesn't use it

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

@@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

@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.

@@krustyclassicsgarage o yea bro I watch all your content I got a build going but u gone hate wat I’m finna say 😂😂I bought an lq4 core for 200 and it spins no problem 115 thousand miles on it

@@roadboiipluckiee6938 fighting words right there

Wife is having the floors re done lol

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.
