Can someone provide a picture for where my horn button wire from the bottom of the column is supposed to connect? I don’t read schematics well so a picture is worth a thousand words…
Thanks

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.

Thanks, so one of the terminals circled in red on the image below?
My truck didn’t have any wire. I bought and installed a wire kit that goes in the steering column. So now I’m left trying to be sure it’s connected properly.

That black box between the two horns is the horn relay. One terminal connects to battery voltage, another connects to the two horns. These are already connected, so they shouldn't be hard to identify. The third terminal connects to the horn wire from the steering column.

I see that in the pic you show there are wires to all three relay terminals. As Bill says. One of those terminals has two wires, one for each horn. I believe your answer to my previous question is: "There is only one terminal on each horn".
So to continue......another terminal on the relay is for battery hot. The third is for the column wire you asked about.

Those wires shown should be replaced. They are old and fraying. Mark down/make a drawing where each wire goes before replacing them.
Disconnect the negative battery cable while working on electrical.
The wires I see indicate that a new harness is probably a good idea.

You can test your horns right now to be sure they work. Arrange a jumper wire from battery positive post to the terminal on the horn trumpet. One horn at a time. Just tap the jumper wire end on the terminal. Tap tap........beep beep

Thanks so much for the information. I do have a replacement harness. Just not the confidence to install it (properly) on my own. So when I round up a friend to lend a hand it will go in.

Just went out to the green turd to see how it's horns are wired up to the relay. To simplify the explanation, if the relay is positioned with the 3 terminals facing down, the positive wires from the two horns are fastened to the left terminal, main power (mine from the starter's positive terminal) wire connected to the middle terminal of the relay. The wire from the horn button (from steering column) connected to the right relay terminal. Again this is with the 3 relay terminals facing downward.

Bob,
Looking at your pic, it seems like the relay is turned with the 3 terminals pointing upward (just the opposite of mine as explained above) and from what I can see it looks correct with.... the wire from the steering column/horn button is connected to the left terminal, power wire connected to the center terminal. The two positive wires coming from both horns are connected to the terminal on the right.

What Craig said.
Here's your relay picture with notes.
