So I found the problem! It was not in the wire bundle that passes threw the body up by the lift gate. It was a faulty module that controls the wiring for the trailer hook up. It's tied into the left break light assembly. It has a "T" style harness for the break light and the park light and then is spliced into the signal light. The module is tucked in behind the bumper just below the tail light assembly. I removed the "T" connector and cut the wire for the signal light that was jumpered from the car harness and went to the module. It didnt work right away, but not untill i cycled the car ignition to the on possotion without starting the engine. I'll post pictures when I go back in and clean the area up

The LED tail light on my 2013 R/T recently stopped working, driver's side only. It's the inner one, the one on the lift gate (the outer one, which is the brake light, is still working). I took the tail light assembly off, and tested power - there is no power coming to the light. Manually ran power to the light, and it lights up - so the light is good. Even stranger, when the headlights turn on, the reverse light on that one side also comes on, unless you open the lift gate and then the reverse light goes off as long as the gate is open.
 
Any ideas on what is wrong and/or how to fix it?

Common issue, the wiring between the body and lift gate gets pinched and broken. Take a look there.

See above comment.  Wire loom at the top of the gate going into the body
