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
