which wires? There are a million wires connected with my deck. But essentially the harness have rcas coming out of it for the speakers, then all the power and grounds are connected properly. The wire that came loose I am talking about is the yellow 12v acc wire that connects right to the back of the deck then goes to the harness. It broke right at the deck so I tried holding it back in place now the deck wont turn on. It was working fine today before the wire popped out.
