My AC compressor is not engaging. I recently had everything apart up front due to some mounting issues. When I put everything back together I had an extra connector. Its not the 2 connectors used for testing. My question is, is there only the one connection on the back of the AC compressor? Thats the one I have hooked up, its red and round. Is there any other connections to the compressor itself? The extra connector is green and flat with 2 metal prongs. Interesting thing is it looks like there is a jumper in the back of it. I have no idea where this thing goes. If you need pictures, I will try to post them tonight. Any help is appreciated!
