I have a 95 GT with a 5.0 engine. The car didn't come with a rear window defrost and I would like to put one in. I have the rear window installed. Now I need to get the wiring done. I can't find an electrical shop in the Los Angeles area to do this. Is there an aftermarket kit that can help me do this? Or is it simply buying the switch and running the wiring from the fuse panel to the switch then to the rear window connections? I'm hoping the wiring is there, but not used.
