To get the radio out of the dash you can either get a tool made for this or just do what I did. Take a wire hanger - cut the curved ends to form 2 "u" shapes - insert these into the holes in the side of the radio - you will hear a "click" - use a little outward pressure and pull on the unit. The wire you are looking for is blue. The easiest way though is to connect it to a switched circuit in the fuse box. preferably a high amp one.
the12volt.com has excellent info.
