i know this might be a stupid question but i really need a fast answer so i can fix this. My A/C compressor is getting no power at all and i would really like to fix it. I just need to know which wires are which. It has two wires on each end of the compressor. On the pulley end of it there is a dark green wire and a black wire, I believe these are for the power and ground? if they are, which one is which? On the other end there is a lighter green wire with a white line on it and a light blue/white wire. what are these for? Please help!!!! i am attaching a picture as well.

 

I'm hoping that you've found your answer already but if not, I "might" be able to shed some light.

one set, is for engaging the clutch for the compressor. I'm 90% sure that is the set that plugs into the front.

I'm honestly not sure what the back set is. perhaps a preasure sensor, or similar?

Your picture actually helped me a lot, since I am currently putting A/C back in my car, and have long since cut the wires out. so I wasn't sure which ones went where.

Anyways, hopefully, that will get you on the right track.
