GrimmSpeed Hella Horn Wiring Harness for 2015+ WRX/STI

This GrimmSpeed Hella Horn Wiring Harness offers a simple, pre-assembled, OEM-quality solution for wiring Hella Horns on your vehicle. Designed specifically for 2015 and newer Subaru WRX and STI models, this harness features a custom-molded connector for an exact fit and is longer to accommodate all 15+ WRX/STI fitments.

The harness uses automotive-grade 16 gauge wire to minimize resistance and maximize horn volume. Heat shrink, crimp-on terminals ensure reliable connections, while protective wire sleeving provides a clean black finish and protects against abrasion and stress. It installs and uninstalls in seconds with a plug-and-play design that integrates seamlessly with the OEM harness.

Unlike more complex harnesses, this version does not include a relay, as testing showed the slight volume increase was not worth the added complexity and potential failure points. However, the harness can be adapted for use with a relay harness if desired, with diagrams provided in the installation guide.

  • Automotive-grade 16ga wire for minimal resistance
  • Heat shrink terminals for reliable connections
  • Protective wire sleeving for durability and clean appearance
  • Plug-and-play with OEM harness for quick installation
  • Custom-molded connector for exact fit

Fitment includes 2015-21 Subaru WRX, 2015-21 Subaru STI, 2013-21 Subaru BRZ, 2013-16 Scion FRS, and 2017-21 Toyota GT86.

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. One a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. 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, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pullies, phenolic spacers, boost controllers, and many more.
