Rewire your horn from the steering wheel to the horn. Its not difficult, I can't tell you how to take the steering wheel apart but you can get a Haynes Repair Manual. It'll have all you need and more. You can use speaker wire, split it in two. Run one cable from the positive in the battery to the horn switch in the steering wheel. Another from the switch to the horn. You have a short somewhere, to me is easier just to run new wires than to find the short-circuit. Make sure when you run the cables through the firewall you run through a grommet so it does not get damaged by metal. Before anything check your headlight wires that they are not touching the horn.

Welcome to FixYa! You need to replace the starter solenoid contacts, or the starter itself.

Note that the starter is UNDER the intake manifold. This is a VERY difficult job, and is not recommended to those who do not have sufficient automotive experience.

If you DO remove the intake, you MUST replace the intake manifold gaskets, or your engine will not run properly, due to air leaks at the intake mating surfaces.
