I need help hooking up my horn on my firebird. I have the two horn pieces, but no wires anywhere near them. So I need help running the wires form the horn button to the horn. And all the sites I've been on telling how to wire it through the relay shows the relay with 4 prongs, where I only have one with three prongs http://shop.advanceautoparts.com/pro...pe=409&PTSet=A - pretty much like this.

Thanks.
