Homelink Mirror / Radar Detector Install Info?

[consultant1027]

Picked up a deal on one of those Gentex Homelink Mirrors. Comes with a harness with red, black, and yellow wires.

Can anyone help saving me the agony of trying to figuring out installing this on my G37X sedan? First of course is how to remove the old mirror (crossing fingers mirror mounts are universal I assume). Then I see a small hole in the headliner and the front center edge of the sunglass holder/cabin light assembly so I'm guessing that was for if the homelink mirror came stock so just need to figure out how to remove the cabin light cover from the headliner to access the wires and figure out which wires to tap into.

Any help is greatly appreciated.
