7-Pin Connector with opening/closing flap.
If you just purchased your Cayenne or Macan, or if you just added the Cayenne Trailer Package, you will need to add this piece. If you look under the rear bumper, this piece mounts near the trailer hitch. So check your car to see if this piece is already installed. If it's not, you will see a blank black plastic cap with four securing screws in each corner.
This piece will replace that blank cap, and the harness behind the cap will plug into this new trailer plug mount. Once this piece is installed, then you will need an adapter plug to change this 7-pin style to the correct plug connection for your trailer. See the related items below.
