I am trying to install a horn on 2009-Rancher. The horn I have has two terminals and the switch has one wire. Any ideas??

Run a wire from the hot terminal of the horn to the hot terminal of the battery. Run another wire from the ground terminal of the horn to the switch. I would put an inline fuse in the hot wire. Evidently the switch grounds the circuit.

Yep.... Helmut that would be my guess
