These trumpet horns are a bit different design than the single, manifold horn I am also using. (Going to use a switch to toggle use of either type as needed.) The trumpet, aka Town and Country horns, don’t have two lugs at the bottom of the rear dome shaped cover. There is only a single wire on each horn. That wire connects to the drivers side terminal of the horn relay, according to the Eichlen product wiring diagram and actually is one of the things I am not understanding. That wire is not hot, according to the diagram? I don’t understand.
