Product Details

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.

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