Audio Systems: installing cd player in car, duraband cd player, 1986 pontiac 6000

Question
I have a 1986 pontiac 6000 and I bought a duraband cd player from walmart  The colors of the old radio wires and the new cd player wires do not match.  I do not know how to figure out which color wires go to which wires.  Is there any way you might have a color coded wiring diagram or anything else that may help me.  I would be soo greatly appreciative.

Answer
Let see if I can do this from memory.

Orange - 12 volt constant (memory)
Black - Ground
Yellow - 12 volt ignition (switched)

Left Front Speaker - Tan + / Gray -
Right Front Speaker - Dk. Green + / Lt. Green -
Left Rear Speaker - Brown + / Yellow -
Right Rear Speaker - Dk. Blue + / Lt. Blue -

Any other unused wire can be isolated and taped off.  The wires listed above will get you the basic function you need.

Alternativly, you can get a wiring harness that will plug right into the factory wiring plug.  I believe the part number by Metra # 70-1677-1
