68 horn relay going heywire

[dardal@xxxxxxxxxxxxxxx]

As I was driving the 68 Sedan late at night on the freeway, the horn decided to 
start shouting.  Beep-beep-beep!  For a few seconds, I was not sure it was my 
car!  I sped up so that the pack of cars around me is not wondering what I am 
up to, and kept on driving rather fast (85-90) thinking what to do.  At this 
speed, I was passing folks fast, so they would be less bothered.  After a 
while, it stopped honking.

My guess is the relay went.  Any thoughs?  I hope its not the steering wheel 
switch, because that's harder to replace.  For now, I disconnected one of the 
wires from what appears to be the horn relay (to the right f the radiator and 
right behind the horn), so it will not start again.

Any thoughs?
