Plate Lights are Out, Looking for Ideas

[machone]

OK, first post - I've searched the forum for an answer, and didn't find anything applicable -

Just bought a 1999 986 - the car is in great shape, except the license plate lights are not working. I removed the bulb holders from the bumper and replaced the bulbs - the bulbs looked bad, and I assumed that was the problem.

Still don't have either light working. I've checked the fuse, which I believe also operates the gauge lights (which are working). Has anyone encountered this problem before? If I have to, I've found the instructions to remove the rear bumper and chase the wiring harness (which I assume could have come unplugged).

Any ideas? The car has never been reported in an accident, and I can't see any evidence of bodywork, so I don't believe the bumper has been apart recently.

Thanks.
