You're replacing the gauge on the dash or the sensor on the engine? If you're after the sending unit, there may be two sensors, one for the gauge and one for the Engine Computer. Both should be very close to where the upper radiator hose connects to the engine. The sensor for the computer will always have two wires in its connector. The sensor for the gauge will have just one wire.
