Thanks so much for your help. There were a LOT of misleading posts with this switch, some people say it runs of coolant temp, others say ONLY when A/C is on should it run. That is all false.
This runs simply runs of the temperature at the a/c dryer regardless of the A/C system being on or not.

I disagree. Look at your wiring diagram you should see that either the water temp sensor and/or the refrigerant temp sensor on the dryer can actuate the relay to turn on the aux fan which does it first is a matter of resistance...
