What brand of detector do you have? I have the Beltronics 995 and it had 4 wires in the cord. I tried the rear view mirror hook up about a year ago and couldn't get it to work, so I just decided to let the wires show.. The Beltronics I have has the anti detector detector so the police can't detect that I'm using one.Check out the Invisi-cord - if you have the powered rear view mirror it's a piece of cake, takes 5 minutes, you just stick two wire leads into the plug at back of the mirror and connect to your detector. There's also a couple different mounts to hang the detector from the mirror shaft --- not sure what you're worried about - had mine in my F150 that way for years and just did same to my new Ram 1500. Super clean look and a snap to do.
