I have a 2001 gt convertible I just purchased. Previous owner installed aftermarket radio and cut the factory wiring harness out. I have the head unit all wired up now and working correctly. But I have no dash lights. I can take the light blue/ red wire and connect to a 12v power wire and get dash lights. My issue is I'm not sure where to connect the wire to so that it works like it is suppose to with the headlight switch and dimmer.
