No extra connections are needed. This cable fits behind the vehicle's radio and is used as a break-out cable to enable the audio of the hands-free kit to play through the vehicle's speakers.On Audi vehicles there is is no traditional +15 ignition supply so using the standard 10-536 you would need to find a separate ignition supply.
