I am installing a auto-dim mirror and am wondering where the wire that powers the back-up lights is under the dash. That wire disables the dimmer so you can back-up unhindered.

 

Take a look at this photo . It's a picture of connector C501, behind the driver's side kick panel. Even though this photo is showing a connection to a black-yellow wire (for a different application) it gives you a good view of the connector you want to find.

The green/black wire is the one you want. There are other green wires in this connector, but only one is green with a black stripe. It is grounded when not in reverse, and connects to +12 volts when reverse is engaged. This should do it.

 

Thanks, once again this forum making my life a little easier
