Hi all, I am working on an R32 GTR and have run into an issue with the AC. When I got the car, it had most of the AC components, but not functional. I had a new clutch put on the compressor and checked the diagnostics on the dash and all seem good. When I charged the system, it's not pumping. Clutch is engaged and compressor spins fine, but not pumping at all. At the rear of the compressor, there is a plug with a red wire and green wire. Neither have power. I think this is a high pressure bypass valve, but currently is not receiving power. I want to know which wire is the power input and what voltage? If someone can unplug their's and check, it would be appreciated! Thanks!
