1970 road runner horn keeps beeping

hi,i have an original 1970 road runner convertible. I took the steering wheel off the other day .when I put it back on after I tightened steering wheel nut the horn keeps beeping. if I loosen steering wheel nut a little and pull wheel forward it stops beeping.any suggestions as to what to look for.thanks

You pinched the wire. Take the wheel back off. Make sure the wire can't touch any metal in there. When you press the horn ring/button it gives the 12V ground and triggers the horn.

i will check wire,thanks
