It sounds like you may have a short in the Junction Box # e99011 and the Breakaway Battery # 3802308. This is the only way I see power getting to the led light on your passenger fender without having it connected to anything. You will want to make sure this is the only battery on the trailer that would have power to power objects to determine if it was wired incorrectly.
