Auto-Dimming Rear-View Mirror

Auto-Dimming Rear-View Mirror

I got this mirror from a junkyard Cadillac Eldorado.

The wiring harness has 3 wires. According to, there should be a Power, Ground and Reverse Light wire. The Reverse Light wire is so that the dimming is turned off while going in reverse.

  • Power: Magenta/Black +12V
  • Ground: Black
  • Reverse: Green +12V
