Ok it took me a while, but I finally got it figured out. If you look at the gear shifter, there are two sets of wires coming from the engine behind the sprocket cover. Follow them up to the frame and they will turn toward the rear of the bike. Get the one that has a blue and a white wire going into a black plug. Splice into the white wire (I had to add some wire to the kill switch to allow for enough room to turn the handle bars). Ground the other wire to the frame. I used the bolt and hole from where the head light mounting bracket was. Hope this helps, because pro armor and pro design had no clue.
