This first picture is of connector 135 according to the Ford electrical and vacuum manual. This is a connector that goes to the ignition coil and AC clutch and oil pressure sensor and coolant temperature sensor. My question is this yellow/purple wire had a second wire connected to the same pin but the insulation has melted and I don’t know what color it is supposed to be. I’m hoping it is the green/purple wire that comes from the switch on the air conditioner dryer/accumulator because that wire burnt up and I don’t know where it is supposed to go. The second picture is of a six pin connector that goes into the firewall right in the middle of the engine bay and it is disconnected and I have no idea where it goes. It is long enough to reach to the right side of the AC accumulator, but I have nothing in that area that it plugs into.

This is the factory wiring diagram used by Ford techs at the dealerships back in the day. This is the real deal. It lists the color and gauge of every wire in the car, bumper to bumper. It also shows the shapes of all electrical connectors in the car. I've used these diagrams on many of the ground-up builds that I've done. They are invaluable!
