The factory-provided wiring harness has a heavy gauge blue wire for that is supposded to be for the after-market brake controller, and an orange one that is supposed to be a 30 amp hot wire for trailer accessories. I want the hot wire for charging the battery on my trailer while driving. My questions are:

Where does the blue brake controller wire terminate up front? How do I find it to hook it to the unit?

Where does the orange wire terminate? I put a meter on it and there is no voltage so it must not be connected to the battery yet? How do I locate it?

Many thanks!
