When installing The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK77FR on your 2018 BMW X3 once the harness is installed and plugged into the trailer, trailer mode is activated.

The trailer wiring harness has a simple plug and play installation that plugs behind the driver and passenger side tail lights externally. The wire is constructed of 16-gauge bonded wire.

I attached an installation video link below.
