I think that I've seen a diagram around somewhere. I might have to scan it and upload a link if I can't find it online.
Wiring diagram/wire colors
Anyone have the wiring diagram for a 2003 Sierra with the piece of **** Bose stuff in it?
GM seems to generally be:
Tan,grey = Front+
Green, light green = Front-
Blue, Light blue = Rear+
something else, another wierd ass color = Rear-

I had to put an after market head unit it mine to hook up my subs. those converters wont work because of the factory amp. I changed to after market head unit and everything worked fine. You just lose the speed change volume with new head deck witch is no big deal. The colors u mentioned are corect though. But as soon as u try to hook an adapter to them the factory amp shutsdown thats why it loses sound. Change to after market head unit and you'll be ok.
