I am installing a second horn that will have a separate switch. The horn has one wire coming out of it. I was told I should use a relay. my relay has four prongs.
1 for ground
1 to power supply (fuse box)
1 to horn
1 to switch.
The question is, if I only have one wire coming from the horn, how am I to connect both the horn AND the switch to the relay??? It seems as though the horn has to go to the switch, and then the switch goes to the relay, but that leaves an open prong for either the horn or the switch, depending on which one I use.
What do I do??
Thanks!
