CDU, put an ohm meter across the extra sensor you have. You should have high resistance with a cold sensor and low resistance with it hot, something like 30 ohms or so. The gauge is just an ammeter, so a low resistance gives more current flow and a higher needle reading. Be sure to chk. the ground wire from the sensor to ground for a good no resistance connection.
12volts goes through the dash gauge then through the variable resistor (sensor) and then to ground. Tom
