I thought originally that there was one hot and two grounds, but that didn't work.
Thanks for the tip on the mirror. I didn't realize they had map lights on them.

When you rotate the light switch to turn on the dome it is actually grounding the dome light to complete the circuit. I wired mine up with a relay using door jamb switches or the headlight switch to ground the relay and power up the dome light and under dash courtesy lights.
