I have a 1985 C20 with a 350 and factory A/C with a Harrison 434 compressor on driver's side. I removed the compressor from the bracket to access the power steering pump below and when I did, I unplugged the harness to the compressor clutch. It has two wires--a green wire and a black wire that has a ring terminal and goes to a ground on a stud near the alternator bracket. My problem is now I'm putting it back together and I assumed the electrical connector would only go on one way but the plastic is partially broken and I can fully seat the connector either way (see photos). Looking at the compressor from the front of the truck when the compressor is bolted into the bracket - the connector is at the 11 o'clock position. I ohmed out both tabs to the compressor body thinking I could ID the ground tab that way but neither one ohmed out. Can anyone help me with which colored wire (green or black) should be on top? Thank you for reading this post.
