I've got a corner light out on the trunk lid.
I swapped the bulb...still no light.
I checked voltage...no voltage to pin for bulb that's out.
No continuity in wire between trunk connector and lid connector.

Questions are:
Is it worth fixing the broken wire or should the whole trunk wiring harness be replaced? Looks like broken wires are pretty common in this harness.

My research shows most wires are breaking/fraying at the wiring support where the harness exits the trunk lid support and attaches inside the trunk. Looks like fatigue failures from the wire flexing caused by opening and closing of the trunk. I haven't seen any official fixes for this. Does anyone know of one?

Yes, I'd recommend targeted repair first.

Yes, common issue.

TSB advisory action: Don't open your trunk :D

The harness was toast. Replaced the whole thing.

All of the breaks were right at corner on the wire support bracket...right where my thumb is.
