1. the sensor that drives the temp. readout is located on the rear, passenger side between plugs 6 & 8. Should be a one-wire connection.

Temp sending unit is supposed to be driver's side between #1 and #3 spark plugs, single wire. The one above the water pump in the intake is the coolant temp sensor for the ECM. Way to test the gauge is ground the wire going to the sensor with key on. Gauge should go full hot when you do that[8D]
