Got a '76 Stingray that I've put a '95 LT1 engine/4L60e Tranny into and would LOVE to get the A/C up and going.

I'm utilizing Painless Wiring harness and a '95 F-body PCM (Per Painless' instructions). Although the wiring harness did NOT contain the wires needed to run an A/C, I did purchase the correct pins and have added them myself.

Since the engine came out of a '95 Vette, I have the Service Manuals (SM) for the Vette, but only Figure A-6 PCM Wiring Diagram (VIN P) from the F-body manual that someone had e-mailed me as a .pdf file.

It looks like the Vette utilizes an A/C Pressure Cycling Switch to signal the PCM to turn the compressor on or off, while the F-body uses an Evaporator Temp Sensor (w/ a probe inserted into the evaporator).

Doesn't the PCM use low-side pressure to determine (guesstimate) the temp of the evaporator? Can I use the Pressure Cycling Switch if I'm using the F-body PCM? If I MUST use an Evap Temp Sensor and Probe, where do I purchase these? RockAuto.com has something called a "Evap Core Tube Kit" for both the Vette and F-Body (ACDelco part #'s 15-33111 & 15-33131, respectively), but I'm not sure that's what I'm looking for...

Thanks for any additional insite!

 

OK, gonna reword this a bit....

If anyone here has a '94 - 95 Camaro w/ A/C... which of the following do you have:

A) A Low-Pressure Cut-off switch,

B) A High-Pressure Cut-off switch,

C) A Pressure Cycling Switch,

D) A Temperature Switch (w/ probe inserted into evaporator)

As stated in top post (probably not too clearly), I'm trying to put A/C into a '76 Stingray that's using a '95 Vette engine and '95 F-body PCM, and trying to make sure there no "communication problems" w/ the PCM when everything is put together.

Thanks!
