Hello I just purchase a horn kit with wiring and it had no instructions. I mounted the switch connected to the switch and the wires were to short so I twisted another wire to them and took them back to where I mounted the horn under the seat. I then found the horn to have only one connection so I connected a wire ( maybe the wrong one? And took the ground and mounted it to mounting bolt for the horn and took a much larger gauge wire to the negative terminal on a battery. Nothing at all, please help what do I need to do?
