There is a small 3 wire female connector in the harness under the headliner near the rearview mirror that I cannot figure out where it hooks up at. I got the headliner redone and am currently reinstalling it, all of the other connectors are hooked up and the interior lights as well as the sunroof work fine with this wire unplugged.

Have searched alldata, but they do not have an electrical diagram for that area. Does anyone know offhand what that wire goes to, or can anyone post a copy of the electrical schematics for the mirror/sunroof area?

 

Sam, what color are the wires going to the plug? I just want to confirm that the plug I tell you matches up. From the sounds of things, odds are the plug is either for the programmable garage door buttons or possibly for the auto dimming mirror. But, I am taking a guess right now.

 

Finally figured it out of course after I got everything reinstalled and had to disassemble part of it again

At the very top of the rearview mirror by the windshield, there was a cable that plugged up there. Am guessing it went to the auto-dimming feature.
