I'm trying to map out a project for Fall (replacing the umbilical), but I'm already stumped, so I need YOUR help!
I've found the original wiring run through the streetside tubing of the hitch that's been spliced into the current umbilical. The confusing part is that there's another original looking wire running through the curbside tubing of the hitch. This one has a couple of wires from it tied into the current umbilical.
Since all of the streetside wires connect to the umbilical, I'm assuming it's connected to my running, brake, signal lights.
What is the curbside wiring for?? Is it supposed to be spliced in to the rest?
I realize that it's a shot in the dark, so any ideas will be welcomed.
