Using your new Hella horn kit is a breeze. First, find a suitable location to mount the horn using the included bracket and mounting hardware. Make sure it's a spot where it won't get damaged easily. Then, connect the wiring harness following the simple plug - and - play design. You'll be enjoying the loud and high - quality sound in no time. When it comes to installation, always double - check that all connections are secure. Also, ensure that the horn is not blocked by any objects as this can affect its performance. As for maintenance, a simple visual inspection every few months is enough. Check for any signs of damage to the horn, bracket, or wiring. If you notice any loose connections, fix them right away. Keep the horn clean by gently wiping it with a soft cloth to prevent dirt and debris from building up. This will help your Hella horn kit last a long time and keep performing at its best.
