Well I just picked up a new car. It's a 2001 Crown Vic Police Interceptor. It still has the driver side spot. The area on the roof where the lightbar was has wires still, have not traced them down yet. Looks like there is a good mounting point for a radio, or scanner also. Will take some time to go over it all and see what I can do with it but will make for a good project. Anyone with experience setting up vehicles let me know, this will be my first good car for a full set up.
