Horn Button wiring,one,wire,two

How is a one wire horn button hook up to work, I have a two wire horn button now and would like to install a new button but it is a one wire , I know on the two one of the wires is hot and one is ground. Is there a way to hook up the one and get it to work?

Perhaps when mounted on a metal surface, the switch is grounded.

See if you can get continuity between the pin on the switch, and the mount, with the button depressed.

Doc here,

To properly hook up a Stock type horn button, the Button Center wiper is on a "Riding Ground" at the horn ring..The Horn button is a Brush type device that contacts a lower copper ring in the Column, when the horn is depressed..That ring has a black wire that goes to the horn relay GROUND of the Coil.

If you are using a two wire button, One wire goes to hard ground, the other goes to the horn relay Coil GROUND .. No power is run through the horn button.
