Replacing Horn 1998 Saturn SL2

I bought a 2-connector horn from Canadian Tire to replace the 3-connector horn that came with my wifes 1999 SC1. All I had to do is find which of the 3 wires was ground (pretty easy) and then used the other wire of the remaining 2 that didn't honk the horn all the time.

It works great.

So you just taped off the third wire and ignored it?

If my replacement horn doesn't have a relay, how does that work? (I obviously have no idea what a relay does)

Think of a relay as an electric switch. The button that you push inside the car activates the relay, which then causes the circuit to the device you wish to activate to work. It allows smaller gauge wire and a smaller switch to be used inside the cabin of your car.

Thanks for the explanation. But I guess I'm back to square one. Either goto the Saturn dealership and get a horn from them, or...figure out how to add a relay to the generic replacement horn I purchased...

Yes, and it works very well. Since all 3 wires are the same gauge there shouldn't be a current issue.

You should go back to the canadian tire and bring your bill for the horn and tell them you need a relay for it. Even though all 3 wires may be the same guage other parts of the circuit may not be able to handle the current of the horn. I beleave this is likely or the engineers at saturn would not have spent the money on the third wire or a horn with a relay. There is a chance you could cause an electrical fire in your car if you overheat the circuit. personally i would get the correct one from saturn. It might be cheaper in the long run.
