maybe a wire corroded through (or a ground connection)


Check for continuity starting from the back.

I second a ground problem, or possibly the harness popped out when you hit the pothole. Might be easy to find, might need to follow the harness all the way rear to front.

Looking over the wiring diagrams I would look for this splice S404, all the rear lights use this splice to provide a ground.
I would remove the taillight bulb and check for resistance between the black wire and a good ground, battery terminal if needed.
There is not a location diagram for splices but it says its near to C401 or C400 depending on bed style, I highlighted the location of these connectors.

Have you checked your rear bulbs? Is there 12v power to the bulb? Do your stop and turn signals work on the rear?
