Need help wiring up the air conditioning...

So I had a PSI wiring harness installed this past off season and now that spring/summer has rolled around I wanted to get the A/C working again. I got the system leak checked and charged up, now I just need to wire it all up.

My shop is having a very difficult time finding the A/C trigger wire that sees positive voltage so we can use it to trigger the Camaro PCM. We thing we've found it behind the drivers headlight, but neither wire is showing any voltage.

Can anyone give me an assist on finding the proper trigger wire, either on the fuse box, behind the hvac head or ???

TIA!

I haven't got to that yet, but was thinking I'd see if that was an output from the climate control I could use.

What compressor are you using? If GM have you modified the internal valve to make it constant pressure.
Search this site for info on how to do it.
I did not use the PCM to control the ac, I just hooked up GM compressor to the old Porsche compressor trigger. Keep the Porsche high and low pressure switches (on the drier) in the system.

Figured it out. We had the right trigger wires, but my AC switch was bad. Complicating matters was the extra hvac head I had was bad too.

Not sure if I've done that mod to the compressor or not, Admin built my car, he might remember if he did it...

Have a link to the thread showing how to do it?

Which wires did you use to trigger the A/C? Om my list of items over memorial day weekend.

On my car they were hiding behind the driver side headlight. I'll have to check the colors and get back to you...

I just emailed you the PDF of the conversion. I basically just epoxied the hole shut instead of welding it. You will need a small pair of c-clip spreaders.
