I would just run aftermarket wiring. I did it, and it's be better if you plan on up-grading the system. Running ne wire in a B12 is all too simple. Remember, most new headunits need a larger constant and ground wire for them i.e. Alpine, Panasonic, Kenwood eXcelon.
Anyway, here ya go>

FR Speaker> gray+ gray/red-
FL Speaker> sky blue+ gray/blue-
RR Speaker> white/red+ black/red-
RL Speaker> white/blue+ black/blue-
Ground> brown
Constant> black
Ignition> red
If you have any other questions PM me, I have the Haynes manual (B12 Bible!) right at hand. I have electrical system background and can easily de-code a car's wiring.
