Oh you think the 2 wire box works on the 3 wire stator? No way dude, try again! Obviously it doesnt otherwise it would be sparking. On the 3 wire there is 2 wires from the pick up(blk and white)and one from the ignition coil(red). They all have to be plugged in. 3 and 4 wire boxes are interchangeable as there is no differnece other than a spare contact for a kill to be wired in. Google 2007 tomos streetmate wiring diagram and get the right stuff this time.
