Simple Problem. Simple Solution.
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 with our custom connector
When it comes to wiring the Hella Horns 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. Our latest version of this harness has a custom-molded connector for an exact fit and is made longer to accommodate fitments for all 15+WRX/STI’.
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.

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group of car enthusiasts in the lovely city of Minneapolis, Minnesota who are absolutely passionate about what we do. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, MN) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed of....actually, much more. We have a wide breadth of product offerings including: intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
