Well, I can tell you a way to get them working..
You're gonna need some 2amp red cable, a good earth, a relay and some higher amperage cable, probably at least 20amp red/black (figure 8) cable.
I just wrote up a quick 1 step guide, but I'd recommend getting someone who would know what to do with those materials to install it.
Edit: I'll be doing the same (only to my high beams) because my lights flicker when my low and high beams are on at the same time.
(They were wired that way when the xenons were fit and the xenons just seem to draw too much current for the existing cables.
Usually when you put high beams on, the low beams switch off and vice versa).
