aftermarket wiring? The most likely would be to bypass the stock headlight circuit with heavier gauge wiring (so they are properly fed); if that's the case then the lil' white box would indeed be a relay so the circuit is switched by your key.
You can get owner's manuals from KTM:
(older than 2000 via the dealers)
The shop manual is a purchase item from KTM, but you can also find it via some 3rd party downloads (user beware!).

I don't have the manual for my bike, or a wiring diagram. Is that little white box behind the headlight with 4 contacts the headlight relay. I know the wiring on these bikes is pretty simple, but it's all kinda packed into the tiny headlight shell and I don't wanna unravel everything and potentially cause more problems.
