Edit #2, an alternative would be to isolate your horn's housing from ground, connect the hot wire from the horn to the battery (fuse in the line), then run a ground wire from the horn's housing to a one terminal horn button/switch. This would likely be the easiest and safest if you want to keep that horn.
Ah. Gotcha. Thanks a million Tiny. I think I like your Edit #2 idea. Isolating the horn from ground then running a ground wire from the horn housing to a switch does seem like the easiest option. Just for giggles, I'm gonna try that with the original horn button. My simple mind is telling me it should work.
Thanks again to everyone else also and for being patient with me. If I can't weld it or beat it with a hammer, it takes a bit for it to sink in!
