Vanity mirror retro-fit

What I would do is take a test light and see which one is hot at the dome light. I think it grounds through one and the other is constant hot. Take the bulb out and probe it with the doors shut and dome light off. The side that is hot is the one you want to tap. Also, be VERY careful taking the headliner trim off as it is easy to break the clips. I usually use a screwdriver to gently press in the tab so that it pops free. Don't just pull it down as this will only break a VERY hard to find clip.

already down ... when the A-pillar mouldings were loose I was just able to slide them right off the brackets ... that and I am rather fortunate to live within a mile of a parts store that specializes in auto fastners. I'll probe emm and see what is hot when the doors are shut - no biggie.
