Electrickery is a Voodoo field, imo, on modern bikes.
Back in the day when you made a switch and contacts allowed current to flow, closing a relay that powered your high beam, life was simple.
Now, it seams, it's mostly ecu controlled.
Your wish may not be as simple as swapping switch blocks.
You may find that everything plugs and plays, but just as likely that the U.S.A. market ecu's are programmed for headlights on. Full stop.
I know that this doesn't help with your question, but something to consider before out laying hard earned on a switch block.
