Hey all, I’m planning to LS swap my 4th gen Camaro that originally had the LT1. My question is pertaining to the engine wiring harness. I found a good harness that came out of C5 Corvette for a good price. Would I be able to make this wiring work for my application? Or should I hold off and find a decent harness that originally came out of a 4th gen? The engine harness came out of a ‘02 with the T56, which I need, incase that makes a difference.

 

You could probably make it work if your skilled and have everything needed to make the swap. I'm installing an LS engine into a Camaro that came with a V6 and purchased a used engine harness and 411 ECU from a V8 manual car. There's more needed than just the harness to wire up the engine to the ECU and to make this swap a plug and play I needed the entire engine harness including the harness with the fuse block and the wires leading into the dash. I read where you could still use part of the V6 harness but needed to re-pin a wire or do wire splice to make an LS1 run and I've provided the link to this below. GL
