Those bastards!

Maybe you know all this (you probably do if you are doing your own stereo)...

Did you hook up the Yellow wire to power or the ignition. (Red +, Black -) and Yellow is the wire that tells the deck to turn on when power is applied. It goes to the ignition switch. OR you could just wire it to power but the stereo would always be on unless you switch it off or take off the face. The way to find that wire in the car is to use a test light. The test light has an aligator clip the you ground and the other goes to the wire in question. The wire you are looking for will light the test light when the key is at ACC or RUN but will be off when the key is off or out.

I think page 23-196 of the helms manual has the wiring diagram you are looking for. Good luck.
