You may decide that you want to change horns.
You are absolutely right. Good suggestion.
I did tinker with this yesterday. The old Chevy steering wheel is really stuck on there. I created a "puller" but it didn't work. There appear to be two threaded holes in the steering wheel - that I imagine are for pulling, but the threads are so rusty that I couldn't find a bolt to thread into it. I think before I force this thing off I should have a backup plan (like a replacement steering wheel).
When I got the truck, all the wires were cut. There was a push button under the dash that I imagined could be used for a horn button. Since the starter still uses the floor peddle, this is what makes sense. So likely I'll wire the horn to this push button for the interim.
