Have worked out which wire activates front fogs from the switch,got Haynes manual and it says from the switch,it runs straight to fogs,no relay or fuse needed?

Does anyone know why the wire is already in the loom at the switch end and if so where does it go to !, as I would like to use the other end for the fogs!
I've hunted high n low in engine bay for loom and cannot see it,so where does the wire go,
Are the plugs hidden in the black plastic wrap ,as they not outside it
Is there a sub loom and if so where does it connect...

My old xr3i you use to plug another loom in Mr the header tank and that ran the spot lights....
