Does anyone know where the sending unit is that controls the electric fan and tells it to turn on, when raditor gets to 180 degrees?

I'm not 100% sure, but I think it's the two-wire one between and slightly to the right of the DIS and the oil filler cap (when viewed standing in front of the car). It doesn't turn on the fan at 180 deg. The fan will run at low speed depending on engine temperature and vehicle speed if the A/C is running. It will run at high speed if the engine temp is too high. The actual signals to turn on the fan come from the EEC via the IRCM.
