This is at the BOTTOM end of the steering shaft, at the flex coupling, right? 
I'll bet that the wire/connector shorted to the steering shaft. That would make 
the horn blow. That's exactly what happened to my '68 many years ago.  

Maybe that's what you meant.

When you're just driving along, the shaft is "hot" and isolated from ground by 
the insulated bearing at the top and the rubber flex coupling at the bottom. 
Grounding the shaft will sound the horn. Grounding is usually done via the wire 
down the center of the shaft, which is grounded at it's bottom end via the 
gearbox and a ground wire that jumps around the rubber bushings that hold the 
front axle beam.
