It's very simple, it's just live in and live out, the cut out is vibration sensitive, so just screws under the metal bracket, held with two long screws, connector plugged in then wires(2)goes through boot floor in the pump feed line to cause a break, so just find where it has been taped up, untape find the ends where it's been cut, and rejoin into the cutout, then if tripped the pump feed with terminate at the cutout, a simple depress of the white button on top reactivates it.
