Air horn switch

[CFD 4-1-8]

so, many many moons ago, I had an air horn in my POV. My buddy wired it up to a switch/relay. In the off position was my normal every day horn, but when switched on became my air horn. I have plenty of relays and switches and it's the same type of vehicle I had then. I cannot for the life of me remember how it was wired up. This time I am using a code three remote siren instead of just the Whalen air horn kit but I don't think that should make much difference.

Just hoping someone can help jog my memory a bit. I'd like to just use a stainless switch on the dash outside of my switch box. There's only six switches in there and they need to be used for other things.

Thanks!

you need a on - off - on switch. either SP or DP and wire accordingly

You need a SPDT switch. Tap into the vehicle horn circuit as shown.

That simple? Maybe I was just overcomplicating the process. No relay? I'll get after it one of these days and re-do my current setup.

Thanks for the help.
