As far as I can seen the auxiliary front light wiring/switching doesn't involve anything to do with the PCB Rog mentions or indeed any relay.
Richard I haven’t see anything ‘concrete’ to suggest that is not what they have done. The front fog functionality (ie.not on with main beam) could have been built into the pcb utilising those little 12A pcb mounted relays

Please please let me be wrong…..
At the end of the 2016-2014 Classics parts book Rog there are various wiring schematics including three variants of the chassis loom with the first two attributable to earlier models it seems since the last one is dated 2007.
In any case on all three a front fog light switch connector is shown fed from the o/s sidelight fuse12. With the switch present this feeds through to the front wings each side. The o/s fuse together with the n/s one are fed directly by the stalk light switch when sidelights selected. This stalk switch is fed by a further fuse 18 to protect it, in turn fed by fuse 8 in the high current set which fuses the main fuse box. All of latter are fed directly from the battery. Phew!
Draw your own conclusions but I cannot see any intervention by PCB. The rear fog light circuit is a different matter of course to comply with regs.
