I've found information on how to wire the relay (left pole to horn, center pole to battery, right pole to horn button), but I'm stumped as to wiring the actual horn. It has two poles/connectors; I'm assuming one is positive (+), the other negative (-). However, there is only one wire leading from the horn to the relay. So...what hooks up to the other pole (on the horn)? I assumed it connected to a ground...however, when I do so, it completes the circuit and the horn sounds. I've tried every variation I can think of, but to no avail...at present, I've hooked up the horn directly, without a relay. However, I understand that's not the best (and safest) way to go.
Any help/suggestions would be greatly appreciated.
Thanks! | | |

That closes the contacts & sends power to the horn.If the horn has 2 terms. yes you would ground one. If it blows you either have the relay wired wrong or it is defective. I,m not shure if it,s nessesary to have the relay grounded but won,t hurt.

I suppose you could just not use a relay but it seems like the intermittent connection might damage the horn button components quickly with such a large load going through such a delicate component.
