While detailing the engine today I noticed that I had a broken wire. I know it is an AC wire but can't find where it connects.There are 2 green wires coming from the firewall that go into a white plug and then exits as 1 black wire.It is here that wire is broken.I looked at rear of the compressor but could not find the other end.The compressor does have a ground wire and it is solidly attached,so I know it not that.Where else is there an electrical connection?TIA

the other green wire goes to the dryer bottle on the right, next to the radiator. good luck, chuck.

OK,lets try this again.On the drier bottle there are 2 green wires that extend near the radiator and goes down near the compressor.Here it becomes 3 wires.Two wires extend toward the firewall and into the car.The extra green wire becomes a "plug" and continues out as a BLACK WIRE.It is obvious that wire broke off from somewhere. what is not obvious is from where.I think it should be connected to the compressor but I can't find the broken end of wire anywhere on the compressor.Where is the compressors' power supply?Does anyone have a wiring diagram for the ac,1990 240? TIA

once the green wire comes back from the dryer, there is another green wire that goes to lh pin 4. the black wire is power to the ac comp. if all is well with the ac, then you should have power on the black wire and all the green wires with the ac on. i guess it broke off from the comp. good luck, chuck.
