Re: Gentex Factory Mirror Wiring?
The connections to a Gentex mirror (with comp and temp). The connector pin numbers are found on the wire incursion side of the mating connector.
GM / wire harness color / function
PIN 1 / PINK / POWER +12 volts
PIN 2 / BK / CHASSIS, GND
PIN 3 / LT GRN / BACKUP LIGHTS
PIN 4 /GY / TO AUTO DIM OUTSIDE MIRROR
PIN 5 / PINK / TO AUTO DIM OUTSIDE MIRROR
PIN 6 / DR GRN/WT / TEMP PROBE
PIN 7 / BK/WT / TEMP PROBE
Note: Pin 3 is to be connected to the backup lights to turn off the auto dim feature in reverse.
I have been told that "If you intend not to use this feature connect the LT GRN wire to chassis ground. If this pin is floating the auto dim will not work properly." I have not connected this yet and it seems to function propoerly except of turning off the auto dimm when the vehicle is put into reverse. Hope this helps.
