I tried installing my CD player in a 1989 SHO. I couldn't find the wiring schematic anywhere but when I connected the radio with the standard coloring scheme the radio came on Ok when I started the ignition. All the lights in the dashboard and interior (doors etc)were out when I started the car again and the radio doesn't come on anymore either. THe car starts and runs Ok and the headlamps comes on but not the indicators. I am hoping it is just a fuse. Does anybody know which one or what else could have gone wrong?
