I have done somthing entirely different. I have installed 2 8" neon lights in the back one behind each head rest. I just ran the wire to the front of the car and spliced into the stock wires for the under dash lights. I also have 2 more 8"s under the dash one on each side. They are all running off the wires from stock under dash lights. They look sweet as hell and were easy to instal.
