DESCRIPTION

The GrimmSpeed Hella Horn Wiring Harness is a simple, clean solution for wiring Hella horns on the 2008-2014 Subaru WRX and 2004-2014 Subaru STI. Designed to work seamlessly with GrimmSpeed BroTie Brackets, this pre-assembled, OEM-quality harness eliminates the need for custom wiring. With a true plug-and-play connection and durable construction, installation takes just seconds while keeping everything neat and factory-like.

WHY?

This harness was built for reliability without unnecessary complexity. GrimmSpeed testing showed that the small gain in volume from a traditional relay setup was not worth the added wiring, fuses, and potential failure points. By focusing on quality materials and a simplified design, this harness delivers strong horn output, easy installation, and dependable performance, with the flexibility to adapt to a relay setup if maximum volume is desired.

FEATURES:

  • Automotive grade 16ga wire for minimal resistance and strong output

  • Heat shrink terminals for secure and reliable connections

  • Protective wire sleeving for a clean look and added durability

  • Plug-and-play design for quick installation and removal
