Kbeitz, The way to wire the reversing switch is to use a double pole double throw switch that a is momentary or self centering switch. That is a switch that self centers in the off position that way you don't need an off and on switch at all. You could wire an off and on switch as a safty switch in case the foot switch gets stuck in one or the other position. The bottom of the switch will have 6 lugs on it. Be sure to get a switch that can handle the amount of amps required by the motor. The diagram below shows how I would wire the switch. The 6 small circles represent the 6 lugs on the bottom of the switch. The 2 wires shown crossing in the center of the switch are not connected to each other. One crosses over the other and both are insulated from each other. .
