3rd brake light harness problems

Only the first light bulb (going R-->L) works on my third brake light. I tried replacing bulbs and there's no change.

What now? Buy a completely new harness?

Get a probe type electrical tester and try to determine where the electricity stops, on that harness, and then try to determine why it is not making it to the light bulbs.

Would a 12V test light work? Instead of a meter...

Also, my trunk light at the end of that harness does work.

Yes. That is the type that I was referring to. The one that looks like an ice pick so that you can pierce the insulation and test the wire.

There must be a break in the wire somewhere.
