How to fix a "rigged" up car horn?

I have a 97 Monte Carlo which I bought used. Some less than intelligent person wired up the horn to a doorbell switch, which he then mounted on the dashboard. Horn works when I push the button, but it is very sloppy looking and just unnecessary. There are two white cords running through the front of the dash, into the engine compartment. One cord looks like it is simply a ground, and I haven't followed the other one.

The horn does not work when I push the steering wheel down (obviously), because it is rerouted to that stupid doorbell. I know nothing of horns, but I would guess the relay isn't working? or maybe the wires for it aren't?

Either way, I would like to get this fixed, as it has been bothering me for awhile now. I just hope it isn't to difficult or expensive. Lastly, will the driver's airbag be a problem considering that's where the horn is pushed? Any help is greatly appreciated!

    The horn was probably hooked up with the button on the dash to save money. Repairing the horn button on the dash could be an expensive proposition. The horn works not by supplying electricity to it but rather by supplying a ground to it. If there are new wires running to the dash mounted horn button it is probably because of problems with the old wiring inside of the wiring harness. A new wiring harness is expensive and electrical problem troubleshooting is also expensive. It would be cheaper to let things be. Good luck.
