GrimmSpeed Hella Horn Wiring Harness Subaru WRX/STI 2015-2021 / Subaru BRZ 2013-2021

When it comes to wiring the Hella Horns on your GrimmSpeed BroTie Bracket, we have you covered. Say goodbye to the hassle of making a Hella horn harness from scratch and hello to our simple, pre-assembled, high-quality harness that makes installation a breeze. Our latest version features a custom-molded connector for a precise fit and is longer to fit 2015 and newer Subaru WRX/STI models. Unlike other harnesses, ours does not include the Hella-provided relay as standard. Through testing, we discovered that the minimal increase in decibels was not worth the added complexity and potential failures of using a relay, inline fuse, and direct battery wiring. However, for those who desire maximum sound, our harness can be adapted for use with a more complex relay harness. Don't settle for less when it comes to your Hella Horns - trust in GrimmSpeed.

Simple Problem. Simple Solution.
