Help needed on wiring for A/C compressor on '91 760 Turbo. I was looking at the compressor the other day and noticed that there are two problems: 1) The blue wires that bolt onto the back left mount, the nut is missing, causing the wires to be loose. Any idea what size the nut is for this bolt. Once again, on the engine side, very back mount of the compressor. 2) Two black wires come out of the compressor. One goes into what appears to be a fuse connector in-line with a yellow/red striped wire. I need to know where the second goes. It has an eye-type connector on the end, but is is hanging loose. The eye is too small to fit on the previously mentioned bolt missing the nut. Would like to see if these problems are the cause of A/C not working prior to doing anything else.
