Help!
I have a 2012 JK Sport. My radio is stock and when switching out to upgrade all went smooth (new radio working) until I was putting everything back in then everything went black, so I tried putting stock radio back and now no power to it. I am thinking ground wire, but I am not sure what I am looking for. The only things going into radio are plug (1) with a bunch of wires and antenna plugs (2).
Currently have stock radio back in . Any ideas? Where is ground wire?
