DETAILS

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.

QUICK SPECS:

  • 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

FITMENT:

  • 2002-12 Subaru Impreza
  • 2002-14 Subaru WRX
  • 2004-14 Subaru STI
  • 2003-08 Subaru Forester
  • 2002-15 Subaru Legacy
  • 2002-15 Subaru Outback

Worth getting

Definitely worth the money, literally took me a couple minutes to install the entire horn assembly (once the bumper was off). Just plugged in and done. If I ever by another pair of horns this harness will be getting purchased with them.

Turns an hour job into 5 minutes.

To wire everything up correctly, make it look pretty, and protect it from the elements would have taken some work. This kit accomplishes all three of those goals for under $40, which is a pretty good deal imo.
