D. What is the free black cable on the Gateway car harness?

The free black lead on the Gateway harness must be grounded / connected to the metal chassis of the radio or car. In case of BMW you don’t need to connect this lead separately.

If this cable is not connected on Audi or VW, then the Gateway won’t work at all (!).
