Ive got the repair manual with all the wiring diagrams, but no scanner, maybe theres a specific part I cold type out for you? you just need to know the order of the wires in the harness? dont you just match up the colors?

I posted this a while ago:

Power Connections

Constant 12+ Blue/Yellow
Switched 12+ Gray
Ground Brown
Power Antenna Black/Red and Pink/Blue connect both wires to the radio's remote wire.
Illumination Green

Speaker Connections

Front/Right + Light Green
Front/Right - Blue
Front / Left + Pink
Front / Left - Purple
Rear / Right + Red
Rear / Right - White
Rear / Left + Black
Rear / Left - Yellow

Uppitycracker: you can't just match up the colors. Car makers use whatever colors they want the aftermarket companies settled on "standard" coloring but even then you should double check.
