MadMikes links are a good place to start.
Is the Kury switch the 3-button reservoir mount?
P/N 7803
I installed mine a few years ago.
I'm using it for 2 sets of driving lights. Each set is 110 watt draw total. BTW I never run them simultaneously, too heavy a draw that way. The fork lights are daytime and the Cobra mounted Landing Lights are night use.
If I recall my Kury switch box for the 2 aux light pairs is tied-in between my switched power source (accessory fuse block) and the relays for the lights.
I also have tied in Chet's 4-Way Hazard Flash design to the third Kury switch. That tie-in took some wherewithal and of course I didn't write it down nor am I able to remember how other then it gave me some trouble. As it turns out the green LED on the switch for the hazards flashes along with my OEM indicator when in use.
It's worked very well for about 40k miles.
BTW I solder all my connections in hopes I don't have to chase a problem in that tangled mess I wove
