Any ideas where to start looking? I have no idea how the previous owner wired them. I tried to trace the wires FROM the super tones, and they lead into some wire loom towards the drivers headlight.
You CAN wire them to the stock horn wires, which join a wire bundle shared by the headlamps - at least on my BD Leggy. That's probably what you're seeing. If there's a relay, then there SHOULD be a wire tapping power from the battery's positive lead as well. Might start by trying to find that wire and trace from there.
This is the ideal wiring setup for the horns. If all else fails, you might just rip out the wiring you've got already and start over. Total cost to you should be about $15-20 for wires and a relay at an auto parts store.
