In the drawing, the loop between the B & C breaker corresponds to the loop in the photo, and in the photo, that loop is identified as 12 volts from the battery, which also attaches to the C breaker on it's line side. On the B breaker in the photo, the load side has two wires on the load side, one goes to the pump motor terminal and the other wire on the same load terminal probably goes to the main panel inside the trailer, which is how our rig is wired.
