Unless I'm mistaken, and that's a very real possibility, the mechanical fan is switched on and off mechanically by an integral clutch. I believe one of the two temperature switches you are referring to controls the aux cooling fan and the other provides engine temperature data for the computer.

I don't know which plug goes to which sensor, but hopefully someone who does know will chime in.
