This dual horn harness for all Veloster & Veloster Turbo models will allow you to have a plug and play wire option to connect two factory Hyundai horns into the existing single connector. In other words, you can get twice the volume out of your horn by adding a second in the car without any splicing or cutting of wires. Alternatively, you can cut off the female connectors and use it to connect any aftermarket horn set to the car without cutting or splicing the factory harness.
