In order to make my stock horn louder, I decided to add a few Hella horns under my truck. These produce a much louder, higher pitch sound than the stock horns. When used together, they are a great way to let someone know you are there. The installation wasn’t difficult, just time consuming. I wanted to keep the new horns close to the stock horns, while keeping the relay next to the battery. This meant I would need to run multiple wires across the front of the engine bay. The hollow front radiation support proved to be a perfect wire conduit.
