The mirror with maplights came out of a mid 80's Olds Ciera. Three wire hookup. The orange and white wires of the mirror were tied into the dome light wires of the same color. This provides light when either the door is opened or the headlight switch is turned to light the dome lights. The black wire from the mirror goes to a constant ground so that the lights can be switched on when needed. Wire was wrapped in black tape and run under the trim for the headliner and then down the A-pillar.
