Woaaa, that is not GM Factory wiring! That is the standard wiring colours for the aftermarket stuff. Gm radio harnesses don't even have a red coloured wire in the harness.
After about 1980 and probably earlier, this is GM standard:
yellow=12v acc.
orange=12v constant
lt blue=rr spkr -
dk blue=rr spkr +
yellow=lr spkr - (not to be confused with yel 12v acc)
brown=lr spkr + (not to be confused with brown park light wire)
dk green=rf spkr -
lt green=rf spkr +
gray=lf spkr - (not to be confused with with gray dimmer wire)
tan=lf spkr +
gray=dimmer switch
brown=park lights
black/white stripe=ground
