If horn and wiring is original, it will be a wire with a black tracer. I goes to the proper horn terminal. The other horn terminal needs a wire with red tracer coming from ammeter.

I don't think there is a "proper" terminal. Either will work for either, You are just grounding the circuit to the column. Which is chassis ground.


Don't be intimidated by an old wiring diagram. It's just lines representing actual wires going from one place to another. All labeled usually as to color, size, and name/drawing of component.

If horn has only one terminal, then your system uses a relay and is wired a little different than I described. I do not know what you may have. So advise how many terminals on horn trumpet.
