Does anybody know which wires are what for the System 10 in a 91' Celica? I've looked at the diagram on install dr. and they are not the same. I bought a harness, but that also does not work. It seems all of the instructions are for the basic sound system and not the system 10.

I don't know anything about the system 10.

But you can do some testing with a DMM (digital multimeter) and find out what each wire is for.

The only way to integrate System 10 is to gut it...like Bose. It's too integrated within itself that trying to accommodate it is not worth the time and trouble.

Yeah, i talked to a guy a best buy today. He actually owns an all-trac and he said it would take him 15 min since he's done it already. Seems like the best way to go -- I don't feel like messing with it
