I too have the green light on my 2002 Concorde Limited mirror, wish there WAS one on the XF autodimmer, but noooooooo .....

1. cover the windshield side sensor ( make it think it is night time )
2. shine a flashlight on the mirror side sensor, the mirror should dim down.

1) you only get ~ 25% thread. Into pot metal (cast zinc). It is not a #7 hole. You'll want to make a stud assembly using a very thin nut inside and outside and a 3/4" long stud or set screw, or use a Button Head screw from the inside, and a coupling nut on the outside. Anything larger (read: taller) seems to interfere with the mounting hardware inside when you twist the thing back into place.

2) If you do try to tap it in place, there is ~ 5/16" space inside the shell before you hit the mounting hardware. Use a bottoming or plug tap.

Best of luck, though. It's one of the things I plan on doing one of these days too. I bought one of the Auto Dimmers from Alaxfire too. Nice feature they decided "der Americaners" didn't really need...

Raised the mirror higher than my normal viewing pleasure, tightend the bracket down and moved the radar detector into position and adjust the mirror down to my proper angle, which snugged it against the detector.. should prevent any bounce rattle that way.

The #'s are inside where the pins come out and are numbered 6.5.4.3.2. and 1 (when looking at the inside of the connector) hope this helps some one in the future. Although I have not done anything for the reverse light, I'm just going to live with it working all the time.

I will say this, this option should of came with all the Xfires it is really a neat addition
And thanks to OCR-XFR for the great write up
