Ariel Owners Motorcycle Club

Good day to other Ariel owners from across the pond. Does anyone have a wiring diagram for the India made repro Lucas MU42 headlamp switch. It is quite different from what was on my 1950 red hunter, my only real question is the copper rocker, for all the wires and colour codes I followed the Ariel diagram for a negative ground. The rocker is not shown as part of the switch in 1950.

Here is a copy of the diagram that Draganfly supply when they sell an Indian switch.
