Before getting started, make sure you have the necessary equipment, including a horn kit, wire strippers, electrical tape, and a wrench. Following the manufacturer's instructions, you can easily mount the horn in a suitable location under the hood and connect it to the vehicle's electrical system. Once everything is properly secured and connected, you can test the horn to ensure it is working correctly.
