Of course that means you can't put the taillight lens back on correctly in order for the pigtail to hang out.
Whoever installed it cut the bezel and cracked the lens to feed it through, so both of those need replacing now. At least they didn't dimple the fender.
It is certainly an *interesting* solution, if not a *good* one.
Edit: the other weird thing is that the truck had trailer wiring badly spliced in under the bed too.
Whatever, it will all become correct as I replace the wiring.
