Hello,
I have a 99 Grand Am GT and I previously had a 97 Grand Prix GT that had a self dimming rear view mirror in it and I loved it, so I'm wondering if it is possible to replace the one in the GA with one from some other GM car. I noticed the plugs on the back are different but if anybody knows which wires are what it might be possible to use the old wiring with the new harness. Any ideas are greatly appreciated. Thanks in advance.
