diesel97 Posted July 4, 2018 Report Share Posted July 4, 2018 (edited) I have a 2017 edge Sel. I am trying to wire in a radar detector to my auto dimming rearview mirror. Any ideas which wire is pos and neg? I had it wired up in my 2010 fusion with no issues and a search on this forum does not give adequate info. Thanks in advance for the help.

enigma-2 Posted July 4, 2018 Report Share Posted July 4, 2018 Black is ground, yellow is positive. The video is for an Explorer, but should be the same. Do use the wire tie to provide strain relief as wires are only pushed in. 2 Quote Link to comment Share on other sites More sharing options...
timfountain Posted July 5, 2018 Report Share Posted July 5, 2018 I tapped in from the fuse box under the steering wheel with a save-a-fuse. Hardest part was getting the fuse out and back in, it is a bugger to get to. I think it was F22 or F26. Accessory fuse anyway. I poked around in the mirror area and could not find anything useful to tap into. Mine was for a dashcam BTW. 2 Quote Link to comment Share on other sites More sharing options...

candurin Posted July 13, 2018 Report Share Posted July 13, 2018 Do you have a blue wire? That should work. 1 Quote Link to comment Share on other sites More sharing options...
diesel97 Posted July 13, 2018 Author Report Share Posted July 13, 2018 Do you have a blue wire? That should work. 3 wires with 3 different shades of blue LOL. Going to make a post on Radar forums they will have it Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted July 13, 2018 Report Share Posted July 13, 2018 There are different mirror configuration's depending on what's installed. Try measuring the voltage between the black (ground) & gray w/blue stripe -or- solid yellow (depending on your setup). Power should be on with car in run, and after shutting off, stay on until door is opened. 2 Quote Link to comment Share on other sites More sharing options...
