 Simple Problem. Simple Solution.

  • Automotive Grade 16ga Wire - Minimal resistance for maximum volume
  • Heat Shrink Terminals - Heat shrink, crimp-on therminals ensure a reliable connection
  • Protective Wire Sleeving - Clean black look, protects against abraision and stress
  • Plug-n-Play with OEM Harness - Installs and uninstalls in seconds

When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie, we have you covered. After some testing, we determined that the additional few dBs offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness using automotive relay, inline fuse and additional wiring directly to your battery. Fully pre-assembled, our simple harness will allow you to plug and play in seconds. Should your heart desire those last few ounces of ear-piercing goodness, our harness can also be adapted for use with a more complex relay harness. Diagrams for that configuration are included in our installation guide below.

Fitments:

  • 2018+ Subaru WRX and STI

Easy to Install and In Stock!

Everywhere else seems to have their harnesses on a 2-3 week back order. Grimmspeed got it to me in a few days so I can actually use the horns that I paid for!
