They then showed the yellow quick connect on the back of the steering wheel similar to this one:
What they never mentioned was anything about how the steering wheel talks to the car. In the connector image, I see wires going into a box below the quick connect collar. Would I be correct in assuming that deep inside the collar there is a plug/socket that connects the controls to the car?
I feel safe in assuming that it's not a wifi or Bluetooth connection, so it must be mechanical, correct?
