lights fog connector

Going to fit some Givi S310 lights. Can I connect them using one of the spare ignition on connectors behind the screen or does it have to be the battery? I want them only to be active when ignition on not a permanent live.

Has anybody fitted them, made by SW Motech I believe. I don't want them so close together at the front but am thinking about mounting them on top of my crash bars. Does anyone know where they connect into on the bike, is there already a socket waiting to accept them? Presumably the switch fits...
