Give this a try. Hopefully the color codes on pages 8 or 9 will help. Yours should be the same as GM for that year.

It might be too late, but, you can inspect the way your original radio was hooked up. The radio end of the wiring will almost always include speaker wires left-right, front rear. The wiring is labeled as such. Also, the speaker wires will be a smaller gauge and appear diff. because they are in pairs (positive-negitive)Your power wires will usually be red, black, white, green. You will have a "hot" wire, this will be your power with the ignition key turned on. You will have a secondary power wire which is hot all the time. ( for your clock and programming if so equipped ) Also, you can trace your Cars' speaker wire up to your speakers. Anyway, if you have a test light and a basic knowledge of electricity, it can be done easily. If you dont, let a professional do it. This is a classic example of someone burning their car to the ground. If you are not sure, give the job to someone who is. PB
