The b/w wire is hot with then ign on, the other goes to ground through the switch. You will need a relay to make the single wire horns work

I have 2 fiamm horns from a previous bike that I want to install on my Drifter in place of the stock ones. The fiamm have only one terminal, getting the ground from the mounting stud.
Today, I put a continuity meter on the terminals of the right hand stock horn and both terminals had continuity to ground. I don't understand that. I would have thought that one would show no continuity and it would be hot when the horn button was pressed.
I can't find a wiring diagram showing the horns.
Can someone here help, please?
Thanks
