Rich,
If the coolant temp s
Rich,
If the coolant temp sender has just one connnector on it, then it is a variable resistor, with one end tied to ground.
Look at your car's wiring diagram to verify...
Presuming the above scenario is true, then the temperature gauge is simply acting as a voltmeter. So, connect 12V to the "+" terminal on the temp gauge...Connect the "-" terminal from the gauge to the temp sender...And connect the ground from your power supply to the temp sender body. This configuration should produce a gauge reading, once sufficent temperatures are reached.

David
