I'M INSTALLING AN AFTER MARKET STEREO WITH A REVERSE CAMERA AND IT NEEDS A REVERSE WIRE TO OPERATE IT. I NEED THE WIRE COLOR UNDER THE DASH TO HOOK IT UP SO CAN YOU TELL ME THE COLOR WIRE TO HOOK IT UP TO?

I would pick up the reverse signal from the back up lights.

I was hoping to find this wire under the dash to the wire harness at the stereo but guess I'll have to run a wire from all the way from the trunk to it instead, But that will work.
