I'm curious as well. I have the same thing. I noticed it last week while installing a piggyback harness for my Magnum rack. The harness plugs in line with the tail light harness, which is the other plug in your picture.

No idea, but perhaps for the 3-red light bar on duallys? (Seems to be way too many pins for that). How about the rear tailgate spotlamp / bed lamps?
