Yeah, that circuit is more than just the radio. I'd start by examining the other systems mentioned to see if they are working. You've got a short somewhere, it's just that you need to find it.

My guess would be one of the lamps or the amp, as they tend to be the cause of these issues...

Anyway, there are two fuse boxes on this car. Have you checked the fuses under the hood? If you blew one of them, it will kill the circuit but not blow the interior fuse. So, do you have any blown fuses under the hood?

Bob is right about that. Your short is most likely somewhere else. It that ground cable is not connected though, you will have issues with the radio - like the clock losing time, and radio stations not working, and a few other things could happen.

Anyway, to interprate the diagram it helps to know what you're looking at:

The "C#" notations are connector numbers. The numbers next to those notations are the pin locations of that wire within the given connector. If you had a factory service manual, it would show you exactly where that numbered connector is.

The "S#" notations are splices.

The three lines of letters and numbers in each line (which represents a wire) are the subsection of the wiring harness, the guage of the wire, and the color of the wire. (PK/WT is Pink with a White tracer.)

The dashed squares indicate areas where other sub-circuits or systems exist.

The circles with x's in them are bulbs.

Completely agree with ImperialCrown, the FSM is the way to go, especially if you intend to keep the car long term.

However, while you're waiting on your FSM to arrive, go here:

There is a very nice wiring diagram section there for that car, which may help you out quite a bit.

BTW, which fuse was blown?
