I am expermenting with early Mazda RX7 headlight openers. Here's the sweet thing, you need three wires to operate it. One gets power all the time. For the other two you need a relay that feeds power to one with the relay off and the other wire when the relay is on. Then hook the relay to the headlight switch. Then when the headlights are on they will open and as soon as the headlights go off the doors close, automatic, simple and slick. I could scan the diagrams if anyone is interested. The electrical part is easy, all yopu have to do is fiqure out how to mount the motors. I'm going to use the RX7 motors, at this time I still want to build a custom grille and headlight doors, if not I'll hook the RX7 motors to the stock headlight doors.
