Yep, a trip to the junk yard, get the horn and relay. Wire it so the button provides ground to the control side of the relay and the relay provides , you can do either, but, I like ground. The downside to that it, you've got a hot wire running to the horn, thru the coil of the horn and back to the relay. That could be an invitation for an issue, should anything happen to pinch that wire... so, maybe on a bike, the relay should control power. And put a fuse inline. I put a radiator fan over my seat on the backhoe. Took some doing, but, it was worth it. IF the horn has its own fuse, then make note of it. The fuse amperage will tell you what wire you'll need. You can also either clip the wires that feed the horn and have a sample, or look And see what gauge the car wires are. THE stock wires should be well able to deal with the current of the relay control. And, it's not like you sit and hold the button.
