Need assistance with dimming mirror

[touring5]

I would like to get a little help from the E53 community. I purchased n new dimming mirror with compass for my 03 e39 5 series wagon. Got the mirror hooked it up and the alarm LED (clown nose) works and the compass works, but it will not dim. Took it to the local dealer for new parts warranty, and they look up the part number and tell me the mirror is made for the e90, e61, and e53, and was not made for my e39, and that for a couple hours of labor they will wire it correctly and make it work... At over $100/hr I took a pass at letting them wire it.

I've done a lot of research, and everything I have found tells me my car is wired just fine for this mirror. What I'd like a little help on is to see how the X5 is wired, or specifically what color of wires run into the 10 pin conncetor from the car side on your mirrors that dim. Any help would be appreciated! Thanks!
