Ok to close out this conversation, I checked with a circuit tester, it was not hot, even with the horn button depressed. Replaced the horn relay, which a 1" square black plugin box located behind the kick panel on the front passenger side. Now it's hot when the horn button is depressed. Hopefully, after I install the new "Euro" horns nothing else blows.
Don't forget where I live guys: In NYC & Jersey a horn is more essential than 4 wheel drive!
