I have those horns on my '37 and they were an accessory for that year, don't know about '39. These are the same horns as Town and Country but not called that (at least in '37); essentially just dual horns. There was not a special switch like you have for Town and Country horns. Follow Tiny's advice for wiring. You will probably have to provide a wire for the horn switch, extending from where the horn wire exits the bottom of the steering column, over to the relay.
