You need a relay to carry the current. A little more information is needed, do you want it to look somewhat original or could you care less?

I'd have to agree that a relay would work best, but certainly many a Model A's horns work fine without a relay. Model A's horn has power to it all the time, the horn button provides the ground. Is your car 12 volts or 6? Positive or negative ground?

This would be for a horn that required power to operate. If it requires a ground to activate, I would use a normal horn relay.
