Trunk Wiring problems of the 1998 BMW 528

The wiring harness that enters the trunk lid that supplies the lights for the rear license plate and the trunk lid release has frayed at the exact point where the harness enters the trunk lid. The wiring comes in direct contact with the sharp edge at the opening in the trunk lid, and several of the wires have broken at this point, resulting in failure of the license plate lights. In addition, the dashboard indicator shows that the trunk lid is open even though it's locked. I performed an internet search and this seems to be a common problem with several BMW models.
