Hi, the a/c compressor is just a single wire coming out of the front SAM. I've attached the climate control schematic and the driver's side SAM schematic below.

Your original question was for the wiring diagrams which I have provided for you. Please rate my service on the original request. You aren't giving me enough information to help you with the compressor activation. What has been done to the car? What are the fault codes that are stored in the climate control system?
