I'm looking for the thermoquad Carburetor Solenoid Wiring Harness for a '72 Challenger with a 340 and A/C. whenever i run the A/C the idle drops almost to the point of stalling. I have the Solenoid and it does work. I just don't have the wiring harness to connect it to the A/C circuit. I can't even seem to find the wiring diagram for this either. looked in my '72 shop manual, looked in a '72 parts catalog, can't seem to find anything about it.
