DETAILS

Skip the hassle of building your own Hella horn harness—this pre-assembled, OEM-quality option makes installation quick and frustration-free. Our latest version features a custom-molded connector for a true factory fit and an extended length to properly reach horn mounting locations.

Unlike setups that rely on the Hella-provided relay, Grimmspeed intentionally kept this harness simple. After testing, they found that the small increase in volume from adding the relay wasn’t worth the added wiring complexity, additional failure points, or clutter. If you still want to squeeze out those extra decibels, this harness can be adapted to work with a more involved relay configuration.

Quick Specs

  • Automotive-Grade 16ga Wire – Low resistance for maximum horn output
  • Heat-Shrink Terminals – Crimped and sealed for long-term reliability
  • Protective Wire Sleeving – Clean, factory-style appearance with added abrasion resistance
  • Plug-and-Play Design – Installs and removes in seconds using our custom OEM-fit connector

FITMENT:

  • 2015-2021 WRX
  • 2015-2021 STI
  • 2013-2021 BRZ
  • 2013-2016 Scion FRS
  • 2017-2021 Toyota GT86
