There are 2 sensors just for the A/C system. One turns on the condenser fan in an overheat situation, the other locks out the compressor if the car is overheating. The compressor lockout is normally closed, and the condenser fan is normally open.
I would say for sure you can pull the compressor lockout one. It would be the 2-wire sensor at the top. Not sure if you would want to pull the other one or not.
