Therte is a good DIY on ducati.ms for that.

I seem to recall that the switches are the same.
I actually wanted the switch to work in the opposite from how it is stock..
as stock, the lowbeam switches off when you push the highbeam button, but the lowbeam stays on when you hit the "pass" switch.
I would have liked to have the High/low button to light both headlights, but the PASS forefinger button to switch off the low when depressing that button. That way it would have been easy to duplicate the "wig-wag" of EMS vehicles.
