G glider Veteran Member Dec 15, 2007 #2 I'm not familiar with that particular horn, but with a compressor involved it would be a smart idea to use a relay. http://www.hdtimeline.com/electrical_and_lighting_systems/1021-starter_relay_wiring.html

D dangerdan Junior Member Dec 15, 2007 #3 I just did a google search on that type of horn. Amps range from 16-20. Thats sounds like a lot of current . My preferance is a relay. Does anyone know if the horn switch and existing wires will handle that type of power ??

With the relay in the circuit, it's no problem. The relay furnishes the 12V from the battery to the horn and the horn button just operates the relay. Without the relay , it's too much for the wiring.
