The wire on pin1 of the auto-dimming mirror is the 12v ACC wire and pin3 is ground. Look at my How-to for installing a Homelink mirror. You can also get that by installing a fuse tap on the bottom fuse in the fuse panel on the driver's side footwell. I tapped into that one for my phone and a 12v outlet I installed under the dash on the driver's side. The 12v outlet in the center console is on all of the time and I really didn't like that.I am hoping to hardwire my radar detector up to the right on my SGT with tech package and was curious if anyone has info on finding the 12v ACC wire and a good way of gaining access? Thanks!
