I got a little more work done the past couple days. I took two overhead consoles, one from my car and a donor, and disassembled, cleaned and put together one that will go back in the car.
This plug was being a major pain. I eventually cut the plug off and reattached the plug from the other mirror that I was able to disconnect.
The initial problem with my mirror was the prongs that hold on the bulb for the dome light had fallen off. I figured it was easier and worth my time to just spend a few dollars on a new (used) one.
I gave the lenses the usual plastic treatment of sanding and polishing to remove some of the yellowing. Once reinstalled the assembly will be finished off with a new dome light lens.
I also took some time to remove all the switches in the center console, give the trim piece a good cleaning and then reinstalled all of the switches.
