No need to hurry. This could drag on for a long time as in many months or years. What is important to understand is you may never know when the horn or cruise control stop working unless you use them and they're dead, but the Air Bag system is a different story. Two of the wires are for the "initiator" circuit that lights off the pellet of rocket fuel. A break in either of those wires will be immediately detected by the computer. It will turn the system off, turn on the warning light to tell you it's turned off, and set a diagnostic fault code related to that. You won't harm anything by driving that way but the air bag won't deploy in a crash. If you sustain an injury that results in a lawsuit against the manufacturer, lawyers and insurance investigators will know from the computer which code was in memory and when it was set. You'll have to explain why you knowingly ignored a safety warning.
Also, just to cover all bases, we used to worry about accidentally popping an air bag when working around them but there are so many safeguards built in. In particular, when anything is disconnected, those connectors are shorted to prevent accidental deployment due to static electricity. When a wire breaks in the clock spring that break bypasses the safety devices. A nine volt transistor battery is strong enough to light off an air bag. When you walk across a carpet in the house and get a static electric shock strong enough to feel, that is at least 3,000 volts. Sometimes you can generate that much by sliding across the car seat. In actual practice you have to work pretty hard to fire an air bag. The only reason for mentioning this is to warn you of the tiny possibility of what could happen if the warning light goes ignored.
