93 horn location/probs

[co5j]

working on a 93 sonata. totally unrelated to what i'm working on, the horn starts going off for no reason and wont stop until you go and hit the horn button, then it could start back randomly, even blew all night one night until i got there. was going to just temporarily pull the fuse, but that controls other things too. where is the horn itself actually located so i can possibly just pull the wire off of it for now? ignition switch was apparently changed years ago, dont know if steering wheel work was done then that may have pinched a wire or something? thanks!
