That video definitely shows exactly the wires in question, minus the red wire with a bit of loom on it that also goes to that post. I have seen it in other pictures, so now I'm curious what it goes to.

Now I need to hook up to a trailer or find another way to test that my factory controller works and forget the rest for now. I'd like to clean up the way those wires look, but I'm just anal that way. I realize the entire thing seems anal probably, but I want to be certain no loose 12v wires running around my truck not hooked to anything. At least the puzzle is coming together. Thanks for the video.
