series 2 light switch help needed

Hi
I have used an Indian light switch for many years with intermittent problems, finally sucumbed to fitting a so called original switch I bought a few years ago but the wire colours do not match any of the diagrams I have. Basically there are 2 groups of wires, one into the the main connector block in the headset and one for the headlamp connector block.
Main connector block
Green/white
Black/white
Orange
Red/white
Headlamp block
Red
Blue
White
Any suggestions where they might go?
