in past years i remember the pwm connector having the wires at the oppisite side of the molex thingy connected, like 0"0 (in your diagram).

all i can say now is ohm it out to verify that the sensor is working, and double check the code (you shouldnt prematurely stop the compressor; that would be bad. its one of those open-start-forget sort of things)
