P O removed a/c compressor and cut wire connector off wires at compressor. Facing truck it has two wires to compressor terminal. One black one green. When attaching the wires which colored wire should be nearest to driver fender the black or the green.

I could not find a wiring diagram for the a/c system that gives the color or their orientatiom to the plug connection.

Thanks agin for your help and guidence.

Doesn't matter. The operation of a DC solenoid coil is not dependent on polarity.


Solenoid Valve Coils (DC) and Electrical Polarity

A common question about solenoid valve coils is whether the electrical current polarity matters in a DC coil. Most coils with lead wires use the same color wire for both terminals and have no polarity markings. The answer is that polarity does not matter. You can connect the positive terminal to either of the two wires without affecting the operation of the valve.
