The kill switch should be connected to the black and blue wires, the white wire should be taped up and tucked away if you are not using a light.

This is exactly how to hook the killswitch up. Yes, hooking it up to a ground does work but there are some setups that isolate the engine so well that the point of contact is the cables, not a good ground. I ran a wire from the chain guard mount on the motor to one of the water bottle holder bolts. Then whatever grounds for electronics hook up there but I still have the killswitch connected to the two magneto wires.
