I know how to wire an F body LS1 PCM to handle the AC controls, but I've been looking at the 04 GTO pinouts and don't see the pinouts I need to wire it up the F body style.

Anyone every gotten the 04 GTO to control the AC?

ya, that does help, but it doesn't show where the AC request circuit comes into play. Can you help me out with that?

Get a PCM Pinout Diagram for the GTO and look in that, I'm sure it's in there like it is with the F-body.

Sorry can't help with the inputs just the outputs, as I never used AC in my conversion.

I know it comes from the PCM on the F-body cause before I removed the extra ones I traced all the Wires that I didn't need, and that was one of them.

I used the PCM (2002 Camero) to control the Vintage Air A/C in my 1941 ****** / S10 / LS1. Works great, but you have to use the GM trinary switch. Put +12 on the A/C request PCM C2 pin 17 on mine and the PCM will turn on the cooling fan and compressor if the system has a proper charge. The PCM will also turn the cooling fan on high for an over pressure condition. I was pressure testing the A/C and found this out.
