How to wire a 4 pin ss rearview mirror

[onefastcar]

Got a rearview from an ss caprice (map lights and compass) for christmas with a 4 pin connector black and green, black and blue, black and white, and a black wire. The black i assume is the ground the rest i am a little clueless on, i would like it to come on with the other lights when i open the door if possible anyone that has done this please let me know how to wire it in.

Thanks Lewis

Good find! I put one in my El Camino, but didn't really pay attention to the wire colors. One is constant 12V+ (You can use the positive at the dome light, as the ground is what causes it to turn on), one goes to the Negative (At dome light) One goes to ignition 12V+ for the compass & Backlight to turn on, and the other is constant ground.

Black=main ground , black and white =white or courtesy light ground, black and green =orange or curtesy light hot wire, black and blue=12 volt source when ign is on.

Hope this helps the next guy.
