Dan1, the ktm handle bar has the switch control assemblies on both sides L/H & R/H both of them have metal pins just for alignment and up right position only. the Right assembly has a removable pin which allows the harness to pass throughIts a law in Australia that the light has to be hard wired to the ignition, your in NZ? Could be a carry over of convenience if its not an NZ law. You could get it changed, just need a 3 position control and an auto electrician.
I have a unit I want to fit but when I tried the headlight it started blowing fuses. Theres obviously something I missed as there is fewer cables than the OEM one. I have noticed that the handlebars seem to act as the earth for the controls, a steel pin slides into a hole. Is it just me or is this an earth?
