This is the switch I had modified by Jem Booth, The pink link wire enables me to have fog on it's own and fog & spot on together, if I cut the link they will work as separate spot and fog but not together (I think

) I figured that if I had a spot on why not have more light with the fog light too. I run a PODtronics DC system with 5Ah battery. Jem insisted a DC type is required as this has an switching extra blade
I figure they wouldn't be on for extended periods anyway, but have a rewired stator to cope with the power to charge the battery just in case.
Pink wire = fog, grey = fog & spot, white = horn, orange = power to switch, red and blue = hi/lo beam for the headlamp, which is switched on by the ignition switch.
