Our lakester has 3 buttons on the wheel. I drive with my left thumb resting on the chute button and move it down about an inch to shift gears and then back on the chute button. When I had a problem about .100 of movement had the chute out. The third button on the right side is used when we run nitrous. All of the buttons connect a ground to a relay so with only 4 wires we run 3 switches. When in doubt, hang it out.
