Trad constructeur solution is to run it along the edge of the metal mudguard - you can crimp it in the rolled edge - but a) the PDWs don't have a rolled edge and b) the Supernova's cable is fairly chunky (is it coax?).
Securing the cable under the guard can be tricky; I think some people use silicone sealant? Or Gorilla Tape? I guess you want something that's potentially removable. Whether it's better along the mudguard centreline or along the edge may be determined by the clearances.
With the cutouts in the guard under the crown I'd have thought you could run it straight up the fork blade and then just fix it to the underside of the guard, effectively making a 90° turn.

Ah I get it now, thanks.
Shame about these mudguards... pretty sure they're only ones that will fit easily in the limited space we'll have. Might look into options with crimping.By Gorilla tape, do you mean gorilla branded duct tape? Or do they do something more specific for cables?
Not sure if it's coax wire - it's two thinner wires (with their own outers) running through a fatter outer.
Thanks for your help, sounds simple enough if I can find a way of securing it to the mudguard.

Thanks : )
Yes I think under the mudguard is my preferred method.
The frame builder won't drill the forks for internal routing so we're using little loop-shaped braze-ons to pass it up the inside of the fork blade.
It's the exact details of how it changes direction at the top of the fork blade and goes under the mudguard that's difficult to find proper info on.
So far I'm thinking the journey looks like this, with unresolved bits in bold:
Here's a picture of it mocked-up on my (very dirty) other bike:
