Depending on what your buzzer circuit looks like, it should be easy enough to put together a circuit using a transistor to take whatever signal you have and use it to drive a relay. The relay is needed to switch enough current to honk your horn, with the transistor taking the low power signal from your circuit and turning the relay on and off.
