Reverse wire color?

Does anybody know where I can tap into the wire that activates the reverse lights? Or tells the auto dim mirror that the car is in reverse?

I am wrapping up my new stereo install and want the monitor to switch over to the backup camera when I put it in reverse. There is a wire on the stereo to,allow this, but other than running a wire all the way to the back of the car I have no idea where to look.

Thanks!

Tap into the light green wire coming from the gear position switch under the dash on the steering column near the firewall.

Awesome! Thanks!

by doing this, I assume that you are installing a double din stereo?

If so, can you please post some photos.

I have a 92 that I would like to install a double din. The wife has a hard time seeing everything behind her. (my fault, tinted windows too dark)

I will also check the forum search, and all of the impalla forums.

Ian-

What back up camera have you gotten and where on the gate will you be placing it? Looking forward to some pics!

I have a cheap eBay camera that was recommended on the Tahoe forums. I never got around to installing it on the Tahoe, so I'm going to try here. I plan to install it between the license plate lights, and run the wiring through the gate, then up the driver side.
