sure Sonny its pretty simple..1st off be sure you have a good 220/240V circuit into your barn or shop area..two wires into the shifter and three wires out to the motor. I would strongly suggest a disconnect switch or plug to isolate power from the shifter when not using it..no sense having 220V sitting there applied to the shifter if it doesnt need to be..plus NEC also states you to have a disconnect; a plug will do
