72 Horn Bar Wires? Why 2 of them?

[Bob]

Hi,
Have a question and this looked like the place to get an answer...
Just bought a new horn bar for a 72 F250. There was no bar in the truck when I got it. This new bar from a catalog has two wires coming out of the back of it. One flat female tab connector that appears to hook to a male flat tab in the steering wheel. (square peg square hole… pretty simple) The other wire has a funky end on it that looks like it might be intended to slide over something thicker. Was thinking it might get shoved onto the plastic somewhere? Thing is… I can’t find any place that looks like it should go and it seems like it might not be necessary? Maybe used in a different application?
Anybody know what this extra wire with the funky end on it is for or where it goes?

Appreciate any advice…
Thanks,
Bob

it grounds to the steering wheel inside the threads where you hook up a steering wheel puller.

Well I'll be...
Oddly enough I did have that end stuffed in one of those holes but thought to myself... "self I said... This can't be right?"

Really appreciate the help. Gonna pop out the door here real quick and see if that gets it going.

Thanks Again,
Bob
