Correct, the trailer battery(s) has to be in the circuit. The power from the truck is only to trickle charge the battery, if the breakaway switch is operated, the power to either drive the hydraulic pump or engage the electric brakes comes from the battery.
You do have a battery on the trailer, right? I would think the breakaway switch wiring would be wired into the battery today and would stay that way.
