I just finished wiring the mirror in today. Given that the mirror appeared to be a GM product (the plug on it was definitely GM), I couldn't figure a way to keep the switch bypass to make an interior light like the dome light. So in short, the map lights are only map lights, not a dome light as well.
What I did was run 2 wires from the mirror down the driver side A pillar. I found a few constant power sources. My first try was at the red/black going to the headlamp timer. I had originally thought it was a constant power, but didn't appear to be. My next trick was to tap into the Sky Blue wire going into the pop up dash switch. It's a constant power. That one worked. I just crimped a circle bolt down ground connecter to the other wire and grounded it to the chassis by the TCU.
As far as I can tell for the switch bypass, though. The original design was for a switched voltage to come in. I originally connected it to the dome light's power signal, but the map lights would just stay on instead of turn off when the doors closed. I tried putting it on the ground for the dome light and got nothing.
