First you need to use a floor jack & a 4x4 to get the weight
off the legs. All you need for tools is a couple wrenches to take the bar off that goes across to the passenger side leg. The old gearbox slides off, the new one slides on the motor comes with two bolts that attach it to the gearbox and put your bar back on as you took it off. Mount your switch next to the crank handle hole by using a small hole saw that will allow the switch to set flush, run the two short wires (48") that say BAT to the battery
, red (has a 30 amp fuse inline)to positive, black to negative. The two long wires (84") go to the motor. Red-red.........Black - black or if your switch responds backwards, you can reverse these wires, I had to. Ready to go! Don't have a host to sends pics but I can email a couple to anyone.
