Ah, OK.
As I read it, green is the trigger, the head needs a direct feed as well, it's the wire to the right of the two red ones I highlighted.

Thank you. On my way to the garage.

Neil, I have concluded that the '91 diagram more accurately describes my car (it is the last '90 GT imported and it has the factory CD as shown).

I have noted the 3 red + wires that concern me. It appears that one goes from the fuse 21 to the amp. There are also two red wires at the head, one is smaller gauge than the other. Can you tell me the function of each of the 3 red + wires and which should be switched with the ignition? Thanks

Edit" attachment failed, diagram too big to attach

Jim, sorry i did not get back earlier - anyway, based on the 91 diaagram, this is the way i would wire it:

Thank you Neil. That is the way I decided to wire it. Reassuring to know you agree.
I am hoping it will eliminate my excessive battery drain. I can find no other irregularities. My theory is that the incorrect wiring done by the PO allowed the amp to be constantly powered. Thanks again for all your help.

Good Jim, Post back and let me know if the problem is solved.
