You guys have dragged this down a rathole. It was a simple question of how many amps the horn relay might be rated at - nothing more. I know how relays work, I know where to use them, and I know about ratings and wiring. All I was hoping for was that someone could tell me how many amps a horn might draw. And to clarify that, a '69 Road Runner horn.
if your original question had been a bit more detailed we wouldn't be in the rat hole. Assuming what you were asking for and giving the wrong answer could be dangerous at best.
Sorry for trying to help.
