Hi all:

I am installing a used electrochromatic mirror in my 99 F150. It has both temp and compass readings. The mirror came with the lead wire for power and ground for the compass and auto dim but no wires for the temp sensor. There are 6 pins available on the back of the mirror, with the first 3 being used, power, ground, and bl/w wire, in that order.I am not sure what the bl/w wire is for. I need to know which wires do I hook the air temp sensor to?

Also when I hook the power and ground up the compass comes on but will not calibrate. Any help will be appreciated.

Thx.

 

Did you ever figure this out? I have just done the same thing, but lost the instructions on how to calibrate the compass. Mabye we can trade info if you still need help. Mike
