Re: 74 Nova A/c System

The best thing to do is find a wiring diagram for the A/C system. The compressor switch should be built right into the HVAC control head. All you need is power to the switch, a wire from the switch to one compressor terminal, and from the other terminal to ground, unless the compressor has a thermal limiter (pin type connector in back). You will need a diagram to determine how to wire it in that case.
