Grimmspeed Hella Horn Plug-and-Play Wiring Harness

The Grimmspeed Hella Horn Plug-and-Play Wiring Harness is a pre-assembled, OEM-quality horn wiring harness. It connects aftermarket Hella horns to your factory horn connector. You don't have to cut, splice or build a harness from scratch. Grimmspeed designed it to work with its BroTie bracket and Hella horn setups, so you get a clean, factory-style horn upgrade.

Key Features:

• Plug-and-play design: Connects to the factory horn plug and installs or removes in seconds.
• Automotive-grade 16-gauge wire: Keeps resistance low so the horns can produce their full volume.
• Heat-shrink, crimp-on terminals: Give a reliable, durable electrical connection.
• Protective wire sleeving: Gives a clean black look and protects the wiring from abrasion and stress.
• Simple, relay-free layout: Grimmspeed leaves out the Hella-supplied relay as standard to avoid extra wiring and failure points. It can be adapted to a relay harness if you want to add one.

This harness makes a Hella horn upgrade quick and tidy. Pick the variant that matches your application.
