I think you are right about the S/C, I didn't run a wire in the car for a S/C clutch for a light. My car is still sitting on my car hauler trailer when I done all of this and still is, I was just trying to see if the S/C clutch had anything to do with conditions that needed to be met for the I/C pump to turn on. I just wanted mainly to see if the I/C pump wood run with just the key on after shutting the car off after the pump was running. I'm heading to town now to get some parts to build a circuit to get the pump to run anytime my fans are on.
