Need help w/ stereo wiring

I need to wire up a CD player in an '86 Firebird, and I have a problem. There was a CD player in it before I bought it, but the previous owner took it out. Instead of buying a Scoche wiring adapter like most normal people do, he cut the factory clips off and hard wired it.

My problem is that I need to know what path each color wire goes to so I can wire up the CD player. I.e. Blue - L. Speaker ect.

Can anyone help me out?

If you buy a chliton or Haynes manual for your car they will have the wiring diagram with what each wire is in the back and they are always a good investment but if you want to not bother spending $15 for the manual your local library should have one of the manuals and you can copy the diagram. Good luck.

You guys are my heroes.

If that doesn't work, I know in my car at least each wire has what it is written really small. At least for some of the wires.
