I got with Phil and purchased his mirror harness that had two wires for the 12 volts and the reverse circuit. I got my mirror put in tonight and got the wiring installed as well... Worked flawless and now have a dimming mirror... Don't hesitate to add this to your truck... FYI, the wire running to the junction box by the e-brake pedal is very tricky to get landed... No pictures, but there are plenty in the thread....
Thanks Phil!!!
