Here’s the cleanest way to mount and wire Hella horns on your late-model Subaru or 86 platform. This Grimmspeed bundle combines our proven BroTie mounting bracket with a vehicle-specific plug-and-play wiring harness, giving you a rock-solid mount and an easy, factory-style hookup. No cutting, no guesswork—just a neat install that looks sharp and works flawlessly.
We’ve engineered these components with the same attention to detail we put into every Grimmspeed part: laser-cut steel, durable black powdercoat, abrasion-resistant sleeving, and heat-shrink terminals. The bracket provides a secure, adjustable mount behind your grille, while the harness keeps wiring tidy and reliable. Together, they make getting that aggressive Hella blast simple, safe, and repeatable.
