Do you have the schematics? Unless the wiring is in the steering column and body harnesses you will also have to add a few wires to get the signals to the BCM under the rear seat, which measures the control voltage from the switches and sends a data message to the radio to do what you want. I seem to remember that I read that some folks who attempt this find out their BCM needs to be programmed by the dealer to activate the feature. If you've done the research and all you need is the clockspring to complete the project, I apologize.
