This is nothing more than a curly piece of flexible printed circuit board. It is winds and unwinds as you turn the wheel, it is a poor design, almost as bad as the power window regulators. They conduct electricity to the horn button and the activator in the airbag. There are after market ones available on the "bay" for 135 or so. I really don't care for airbags, I was married to one for awhile. If you go to sell it though you may run into a problem. The horn is a bit of an issue, sometimes you really do need it, sometimes it is required for an inspection. I "repaired" my horn button issue. Disconnect the black battery lead. You will need the following, good quality 22 gauge speaker wire, 15 watt soldering iron, solder, good quality rubber cement, disposable gloves, and a bit of patience. Remove the horn ring retainer, then the airbag and plug. It has been a year so I may have forgotten the exact steps. Remove the clock spring, looking closely you will see the cracks. Lay out a piece of the speaker wire, that is the same length as the clock spring, carefully tin 1/8 on each end. Neatly rubber cement to the clock spring, and the speaker wire. If you like airbags, I wouldn't do this. It is not good practice to repair (no matter how good you are) a piece of safety equipment that you or a love one may rely on. if you want to do the airbag, you will need two lengths, be certain to mark 1 wire with a marker so you don't confuse them. Setting off the airbag when you want to blow the horn is considered bad form. Once the cement sets carefully apply the wire(s) to the clockspring circuit and solder it to the appropriate tabs at the ends of the clock spring. I'm cheap and I didn't want the airbag so it works for me.
