the horn button energizes the horn by supplying ground to one side of
the horn.
If you use the same wire to supply ground to a relay to energize it,
such that when energizedthe relay will supply 12 v to one side of the
horn, ( where ground 'was' ) and connect the other side of the horn to
grnd ,
itshould work perfectly.
