06 Silverado Air Temperature Sensor

Recommended Posts

Posted (edited)

Hello, I have a 2006 Silverado 2500HD and am looking to replacing my generic rear view mirror with one with the compass and temperature read out. I know the air temperature sensor is located behind the grill at the center of the core support, but where do the wires run before going to the mirror? 

 

EDIT: Wiring connects to pins A3 & A4 of the relay block to the left of the steering column.

The encouraging thing is that the wiring doesn't route through a controller, but routes directly through a relay block to the mirror. So adding the auto dimming compass and thermometer mirror is possible. I had to take mine apart and resolder a couple of joints, so got to see inside it. The compass is internal and about all you need otherwise is the thermometer input (the air temperature sensor).

 

I strongly suggest you use a stock wiring harness which plugs directly into the relay block.

 

Good luck.
