Upgrading Premium Head Unit/Wiring

[Superdrive]

Hey all, I recently picked up a 1995 Grand Marquis and I had some issues getting the original factory deck to work correctly. I wanted to keep a factory look, so I acquired a 2000 Crown Vic stereo with CD controls.

Today, I started to install the new deck. Since the connections are different, I've been taking the wires from the original harness and using them with harnesses for the 2000 deck. Right now, the new deck powers up and dims just fine. The point where I am running into trouble (with the exception of hot during start wire) is the wires that go back to the Ford Premium Sound amp/speakers. Can anyone direct me to a diagram or schematic for the 1995 Premium Audio system or advise me on connecting my 2000 deck to that 1995 amp? Any replies are greatly appreciated. Thank you.
