Well, I tried to plug my radar detector in, and it didn't work, so I ran a voltmeter down there, and it read 0. So I went behind the dash to have a better look, and there are NO wires running to it. I believe there should be 1 orange wire that goes to it. I was wondering what/how does it hook up? Do I need to splice it to an orange wire, or does it have a special plug? What gauge wire should I use?
