Horn wiring problem 35 pickup

[Lawson Cox]

I'm stumped (as usual).

Horns won't blow. I think I have located the problem, and that
is that the wire(s*) running from the horn button, down the tube to the light switch apparently has(have) lost continuity. Horns were working fine, but then crapped out for no apparent reason.

I would like to fix it, as easily as possible, which is apparently tapping into the ground wire where it enters the switch, and putting a bypass wire to a new ground, and putting a remote push button in that bypass wire to make the connection when the accessory button is pushed, thereby completing the circuit once again. (I really hate to do that as I want to stay pretty much original.)

Another thought, has anyone ever tried to remove the horn button itself without totally removing the horn rod itself? (It is impossible to remove the horn rod on the pickup without disconnecting the steering tube & switch from the frame and dash, and then take the rod out the rear window? (I am just not up to doing that.)

Is it too difficult, or even possible, to pull the horn rod out about half way, to get to the underside of the horn/light switch, and then pry the tabs open that hold the horn button retaining ring, and remove the horn button itself to check the connection there.? Perhaps I am overthinking that idea.

Sorry to be so long winded, but Lawyers tend to be that way at times, especially when they aren't sure what they are talking about. LOL

* There are apparently two ground wires running through the tube as there are two wires connected to the center post on the light switch itself.
