Hornblasters Spare Tire Delete Toggle Switch

Hey everyone. Just a question on the original wiring of the train horn. Got installed at a dealer, currently when toggled off just the stock horn honks, and when toggled on both the trainhorn and regular horn honk. Sounds a little weird but the dealer told me that this is how it is supposed to be with the wiring from the factory. Can yall confirm this? If this is the case is there any way to wire it so that when toggled on only the train horn and not the factory horn honks? Thanks so much!

Toggle is to activate horns with factory horn. They should have also installed your direct push button so that your horns work with out factory horn. My toggle switch has gone out couple times not sure why. But I got wireless activation and the push button .
