Hooking up a horn: Will it work?
Hi guy's. If you have done the overide like i have, you should have both wires to the overide switch disconnected from everything. One of the wires should be hooked to key on voltage. The other wire coming from the switch will go to the relay. On most relays there arfe 4 or 5 terminals, for this application you will use 4 of them. On the relay you have a signal side and the power side. The signal side will get one wire from the overide switch and the other side will go to ground. On the power side get a wire from the battery to the relay then from the relay to the horn. I do this because i run dual horn. If someone needs a schematic please say so and i will try and find one. I hope this helps.

I know literally dozens of people using the override button for the horn with no relay. Nobody has burnt out a switch yet and this goes back 10 years. I wouldn't recommend using a air horn though as the amperage may fry the switch in this application and a relay would be the safest way to go.

WAIT!!!! Before you guys go hooking a horn up to the purple wire. I ran into a problem. It turns out that the purple wire is ALSO for the reverse light. SOOOO, when you put it in reverse, the horn will go off. I am going to have to look at this agian and see if there is a way to get around it.
