[B]THe electronic coolant temperture sensor (ECT). It's right next the thermostat housing. Just unplug it, unscrew it out, put the new one, and you are set to go. The temperature sending unit is what controls your guage inside the car.
the ect does not run the gage
there are 2 sending units the one near the thermostat housing tell the computer the coolant temp
the one screwed in to the lower intake with one wire runs the gage.
this is what the computer sees in the stock program
