I have a Sensation Go Devil. I am going to use this NOS high/low headlight/horn switch for a kill switch. I have 2 of these bikes with this exact switch that appear to be original to the bike. Unfortunately, everything the wires connected to is missing. I plan on using the horn switch as a kill switch. I believe that is what the factory did. My hs40 engine has the exterior coil wire connection. As you can see there are 4 wires from this switch, one black, green, orange and blue. My question is, is the green wire for the horn and does one of the other wires go to a ground or is the switch itself grounded when mounted? I don’t have a multi-meter but will get one if needed.
