The UK spec bikes had the head light shell switch to accommodate the city light
Look up the CD175A 'sloper' wire diagram...very similar set-up.

Thank you, much appreciated.

Thanks for all the help, turns out it wasn’t a huge mystery after all. The brown / blue isn’t shown on any wiring diagrams I could find and I was trying to figure out what was what with the wiring on the controls that came with the bike, these as it turns out were not factory wiring. I have some NOS controls tucked away and when I checked those there is a brown / blue wire from those, so all sorted now, it is s a feed to the handlebar switch.
