I need to know how to wire the compressor on my truck, it is a 1965 Chevy truck with an 06 5.3l, I have the stock compressor for the motor. I have Old Air Products ac system in my truck and it provides 1 wire for the compressor clutch.

I see the harness has a two wire connector, dk green and black, black should be ground, can I hook up the 12v lead from the ac switch to the dk green wire on the compressor connector so I can have ac?

Thanks guys
