Hello everyone,

Hey I've been working on a swap since summer, but Im a bit hung up on the wiring.

The LS1 has a PSI harness and that's all good, and has its own power. I removed (but kept) my old c207 harness but noticed it has some of the sensors on it as well as the battery connections.

My c100 is intact but has no power. I thought this was strange because in videos of cars online, the c100 has the power and sensors, and the c207 is almost completely useless.

I also installed a vintage air kit, minus the wiring. I removed the old AC wiring, but like the c207, I kept it.

I have the pin outs for the c100 and c207 (sort of, I combined the 85 and 87 I found online), but I'm not exactly sure what wires I need to be splicing to get everything powered up. Admittedly, wiring is like a foreign language to me, so I apologize in advance. I have visited the LS1 swap stickies but it's still not quite making sense. Any advice is appreciated. Thank you.

 

This should help. No power to the C100 means no power to the dash or anything else on the car. Those two big red cables are required
