NAC: Looking for GM website or forum of some sorts...

[Gerard]

Hey!

There is no Audi content in this. Okay, maybe a little 'cos the item
I've got here is intended for an Audi.

Does anyone know a good website dedicated to GM vehicle, especially late
model items, where they speak technical stuff? I need some wiring
diagrams or wiring information in order to figure out the wiring
pin-outs of a auto-dimming mirror from a year 2000 GM of some sorts.
This unit I have has 16 pins, 13 of them wired, and I only figured out
what 2 of the 13 do (for a speaker/mic on the bottom of the mirror). The
unit is equipped with a compass and temperature display and also has the
OnStar interface. I want to try and use the OnStar buttons for something
else and will probably remove the compass and try and wire in a
temperature sensor instead.

Thanks.
