I currently have this unit for sale on ebay. the wiring is simply two wires from the 16v transformer to the appropriate screw terminals on the printed circuit board and then the switch leg from each door bell button at the doors you are using attached to the corresponding terminal screw as labeled on the circuit board.— Purchase or Repair:
