On the camper, the 6th wire is for the brakes. Since I never got around to adding a brake controller on the trike, I just left that 6th wire disconnected. On the second pigtail I ordered, I cut down the wires on the 5-4 converter I also had, connected it to the extra pigtail, and have a small harness that I can use for when I need to haul the cargo trailer. It is short enough where it won't hang and drag on the ground. I just disconnect the permanent 6 pin harness I made and plug in the other 4 pin harness I made.
