If you can't find it in your owner's manual you can try calling your local dealer's parts department with the VIN number. They can pretty much tell you whatever you want by the VIN.

Thanks for visiting FixYa!
Most all older GM cars using Delco wiring (up to about 1989-90) used the same wiring colors.
Locate three plastic plugs fanned out of a single harness bundle. Plug colors are blue, white and black. Each plug has four pin positions and may have four corresponding wires. All plugs are almost square, and have alignment ridges that guide insertion to specific slots at the rear of GM radios. A fourth, smaller and flatter plug may accompany the other three. This plug is usually connected for electronic preset and clock memory.
Locate the following colors on the blue plug for rear speaker connections:
Right: Negative=light blue, Positive=dark blue
Left: Negative=yellow, Positive=brown.
Locate the following colors on the white plug for front speaker connections:
Left: Positive=tan, Negative=light gray
Right: Positive=light green, Negative=dark green
Locate the following colors on the black plug for power connections:
Yellow=12 volts ignition, black=ground, gray=illumination, pink, if present, activates a power antenna.
The small, flat plug has an orange wire to a 12-volt battery for preset and clock memory.
Trace each wire through the adapter plugs, strip the ends applicable to the stereo you are installing and use crimp connectors to mate the wires with the stereo's output wires. Use a test light to test power and illumination connections. Use a multimeter to test for ground wire continuity and speaker connections.
