Fold the small connector over the wire and squeeze together with a pair of pliers until the plastic housing snaps in place. Now plug the other harness wire terminal into the IDC spade lug to complete connection of the power to the mirror. See photo sequence below for details. The remaining two wires for the temperature sensor need to be routed to the front of the vehicle, preferably low and in front of the radiator or behind the bumper. This is required to minimize the effects of engine heat when the vehicle is not moving.
Proper airflow is required in order to give an accurate temperature reading.
Therefore, the sensor should not be located near any heat sources such as the headlamps or in the engine compartment. Use an existing grommet in the bulkhead or drill a hole large enough to pass the connector from the temperature sensor harness through the hole. Route the temperature sensor wires through the hole in the bulkhead and forward to the temperature sensor. Use the supplied tie wraps to secure the wire at a few points along the path of the wire.
