Hi, I'm looking for a wiring diagram for the audio connector.. I've installed a parrot bluetooth kit using the scorche radio connector which only has 16pins wired on the connector and now my audio controls on my steering wheel ceased to function so I'm wondering if its because the connector only has 16 pins out of the 20? not sure on the total number of pins.. I need the diagram to see if radio connector actually contains wires for the steering remote..

Thanks alot

anybody has any idea?
