It sound's like you have too much current running through your horn
button. The horn button should not be directly connected to the
horn. Instead it should ground the horn relay when depressed. This way,
the current drawn by the horn (which is a lot more than you want running
through your steering column) goes a shorter distance: from the battery,
through the relay and to the horn.
Think of the relay as having two parts, the "coil" side and the
"switch" side. When you depress the horn button, it completes the circuit
on the coil side and a small current runs through this side of the
relay. When there is current through the coil side, the switch side of
the relay will close, allowing current (in large quantities) to flow to
the horn. That's the simplest way I can think of to explain it over
email.
Since you did have smoke, you should check the contacts in the steering
wheel for burned pits and carbon. It probably got hot enough to burn off
some oil and grease; hopefully it didn't melt anything copper.
On another note, your email client seems to be spewing some m$
strangeness. Make sure you're sending messages as "plain text" with
"US-ASCII" encoding.
good luck
