  • 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

When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie Bracket, we have you covered. Don’t stress yourself with trying to make a Hella horn harness from scratch when we offer a simple pre-assembled, OEM-quality harness that will allow you to plug and play in seconds. 

You’ll notice our harness does not incorporate the Hella-provided relay as standard. 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 the relay, inline fuse and additional wiring directly to your battery. Should your heart desire those last few ounces of dBs, our harness can be adapted for use with a more complex relay harness.

Took five minutes and got rid of the relay that was always going bad! Can’t recommend enough.

Get this one

This kit was out of stock and I was impatient and got a universal kit. I went through the trouble of installing the universal kit with wiring through the car and booking up to the battery. It was more complicated than it needed to be and failed after a heavy rainstorm got it wet. Finally got this wiring kit. Soooo easy. Don’t look elsewhere, get this kit. It’s the one you want.
