Just completed the installation of a Gentex GENK41a Auto Dimming with HomeLink. Had to buy an adaptor for the windshield bracket. The rest was wiring and a little time. I tapped the switched power supply from the cigarette lighter in the glove box, the ground and continuous power from the interior overhead light. The overhead light has a new led bulb as well (3022-WHP4).
Programmed the 3 garage doors and cleaned the mirror, she's ready to drive
