I don't understand why he would need any more wiring info other than the deck and amp wiring....

He needs a stereo wiring diagram if he's trying to keep his factory speakers and replace the factory amp so he can find out how the speakers are wired, if there are any crossovers or if it's using active crossovers, and the wiring color code at the factory amp location.  Well to be completely honest he doesn't NEED it as it could be figured out, but it sure would make his life easier. 

I think that's pretty much been covered on page 1.

There is no ignition wire in this car as the radio is data controlled. Best bet is the fuse box for a switched power...
