Your assumptions are right. Connect B to battery (or some other high current
source such as where the battery cable connects to the starter motor), S
(switch) to the horn button and H to the only terminal on your horn.

Joe - I have a 12V relay with three contacts that I was hoping to use - they
are marked H, B, and S.
I assume that the H is to the horn itself, the B is battery and S is horn
button.
I would really appreciate a wiring schematic that shows how to wire a horn with
only one contact (positive) that grounds to the body.
Thank you very much!

Rob,
Basically the horn circuit will take a relay. The horn button supplies
the ground to close the set of points inside the relay. When the
points close current flows to the horn to make it sound.
If you would like, I can draw you up the wiring schematic for wiring in
a 30 Amp Bosch Relay.
Joe
