I finally did this today. I found a switched 12-volt wire on the passenger side of the dash and ran a spare phone cord to it. Sure, there may be a switched source in the mirror harness, but probing the connectors on the side of the dash with my meter to find what I needed and tucking a flat phone cord in the headliner was way easier. I spent less time doing this start-to-finish than I did researching where I MAY find a switched source.
