I went out and installed a new DS courtesy light switch and the cool tool-sleeve from CDan (pic below) this afternoon. When I had the plastic panel off, I noticed a green wire going from the tail light plug over the metal edge, and around the carpet toward the tailgate. Later, I took the plastic panel off the PS. Similar green wire running unprotected over a metal edge toward the tailgate. Is this OEM? What are they for? Why are they so exposed to potential damage? Everywhere else I've looked in the truck, wires are extremely well protected (grommets, tiedowns, foam, split loom, tape). These wires appear to be OEM (no taps, no signs of disturbance to the harness).
