CLK SWC wiring

Hi, does anyone know the correct wiring for the steering wheel controls for an '02 CLK55? When I bought the car it came with an Alpine head unit with the PAC adapters for the SWC. I am going back to the original style radio because I prefer the original look. With the new (old) radio installed it plays fine but I am not getting the controls on the steering wheel. I get the "Audio" heading on the instrument panel but that is it. I am wondering if the pins had been changed around when the Alpine was installed. I am attaching a picture of the plug, does anyone know if the wires are in the correct position?
