3 Wire Camaro Coolant Temp Sensor Resistor.

Easiest way I can think of to figure it out, which I'm not even 100% sure if it will work or not, but get a potentiometer from Radio Shack, install it in place of the resistor, and adjust it until the reading on the instrument cluster is the same as the reading in the ECM, then measure the potentiometer for your correct resistance value.

That's actually a darn good idea... As of now my coolant gauge still shows a reading even with the key off. Talk about irritating.
