[QUOTE=flawxy;713127]Thanks for the link. I saw that earlier but I don't think that applies to me. I had 2 horns now I want the one in the link above. Can I just pick a set and plug it in as both sets should be 12 volt? one set has 2 single wire terminals, while the other set has a single wire terminal AND a double wire terminal. I assume one is hooked up to the factory relay and the other is to the steering wheel??? Pardon my ignorance I'm by no means an electrician.

The horn came with a relay and a wiring diagram similar to the one in your link. so should i have bought 2 horns? one for each set?

Thanks for the help,

Dave

Hi Dave, The OEM horn wires are positive and negative. The brown wire with the black stripe is the positive and the plain brown is the negative. The spade connectors on your new horn are marked positive and negative. You could have bought two horns but you don't need to . . . You could just hook up your new horn to either one of the two sets of OEM horn wires but you will blow the 15 amp horn fuse located in the box next to the battery every time you honk the horn. That is because your new horn draws 18 amps of power . . . more power than the two OEM horns so you will blow the fuse. To use your new horn (or even two of them if you want) you'll need to hook up a separate wiring circuit for the new horn using the relay provided with your horn and following the directions on the wiring diagram shown in the "Horn Stop Working" link that MrMiata provided for you. Personally, I am totally electricity challenged and yet I was able to do it. Good luck to you . . .
