Using an original harness allows for restoring the proper operation of the tailgate lighting without the need for system modifications.

In practice, the installation involves removing the interior tailgate trim, disconnecting the old harness, and connecting the new one to the existing mounting points and connectors. Thanks to the factory fitment for the BMW F44, it is possible to maintain electrical system integrity and aesthetic cable routing.
