Using your Perrin HELLA horn bracket is easy. First, gather all the included parts: the bracket, M8 flat washers, and the instructions. Follow the installation guide provided, and it should take about 30 minutes to complete. Make sure to connect the bracket securely to the radiator support to reduce flex while driving. When adjusting the horn assemblies, use the slotted mounting points to move them up or down as needed. Since the horns are sold separately, you'll need to install them according to their own instructions. As for maintenance, the powder - coated finish helps protect the bracket from various climates. But if you notice any signs of wear or damage, contact the manufacturer. Keep in mind that the bracket has a 5 - year warranty, so you're covered for a long time.
