There has to be a wire to the PCM that indicates an A/C on situation form the HVAC controls on the dash. Does anybody know which wire this is? Would it make sense to use it to control turning on and off the E-Fans instead of the compressor switch? This way the fans wouldn't cycle with the compressor, but just stay running when they sense and A/C on signal from the HVAC controls on the dash.
Just wondering if anybody has ever played with this?
