I'm curious what the purpose of this guy was unless turning signals were offered by the factory.
If you're talking about the small tube on the bottom, it is for the horn button wires.
The tube on the bottom of the column is for the horn wire. Some years it's for wires to a combination horn/headlights switch.
If you have a hand klaxon like I do, you can use it to run your turn signal wires down the steering column...makes for a cleaner install of turn signals.
Chris, that type of horn wire tube will take both the horn wires and indicator wires. That's a good thing.
Allan from down under.
The early horn wire conduit is a round tube, with just enough room for one wire! '15 to '17? And there are two screw holes on the top side of the column for the button.
That reminds me that my original horn sounds very weak.
After cleaning the contacts I wonder if there is a horn rebuild thread on here somewhere.
Try doing a Google search on:
