Hello. I have a rear view mirror out of a 99 Buick GS and I was wondering if anyone could help me out with the wires on it? It has like 6 or 7 wires. It's a lighted mirror with auto dim but no compass. I think the orange wire is for the lights and the black is the ground but the other ones I'm not sure what they are. I'm wanting to put this in my 86 Cutlass. Thanks.
