Note that the wire colors may vary slightly depending on the specific year and model of the vehicle, as well as any modifications that may have been made to the wiring harness. Also, keep in mind that it's important to properly match the wires from the harness to those on the radio to ensure proper functionality and avoid damaging the radio or other components in the vehicle.
