    I've "fixed" more things with the volume knob of the radio that I care to admit!

    OK---I am convinced that I need to use a relay on the horns.
    I have a set of dual horns that are rated at 20 amps each.
    Can I get away with 1 relay or do I need to use 2 relays?

    Can someone point me to a SIMPLE wiring diagram for my 2 horns?

    Relays, like most other electrical equipment have a rating as well. Most automotive relays are rated 20 to 50 amps. If your horns draw 20 amps each and you have two then you would need a relay rated above 40 amps. I would recommend going to 50amps to have some breathing room. Don't forget the fuse!!!! I looked up relays this morning and found this;

    50 amps for 13 bucks. Another 5 bucks for a wiring harness to make a very clean install as well.
