Anthony, thanks so much for this write up and video! You made it super-simple to do and left nothing out for us to guess at. Those connectors look to be a bit difficult to get out, but with a pick tool and a couple of junk yard pigtails, should be able to get the two needed wires. I am wondering... there is a wire behind the radio that is used to turn off the auto-dim mirror function while in reverse... could a guy possibly use this for the reverse signal?
Connector 267M
Pin Wire Color(s) Gauge Circuit Purpose
06 BK / PK Normal 140 Disable auto dim when in reverse
Of course, it may not be the ground signal we are looking for. Just a thought. Again, thank you so much for the write up and video!
BTW, your avatar doesn't have facial hair... when the video loaded, I thought "who is this guy?" LOL
Have a GREAT weekend!
