To operate the replace, Montigo has supplied and installed twenty
feet of low voltage wire to this electrical control panel. Connect the
two wire harness to a standard single pole ON/Off switch located at
a location of your choice. You may also extent these wires to any
length, as long as you select a wire of equal quality.
