GrimmSpeed Hella Horn Wiring Harness for 2015-2023 Subaru WRX / STI - GRM040026
$41.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2023 Subaru WRX and STI models.
Upgrading to Hella Supertone or Sharptone horns shouldn't require hacking into your vehicle's factory electrical system. The GrimmSpeed Hella Horn Wiring Harness provides a professional, plug-and-play solution that eliminates the need for wire splicing, soldering, or crimping. Designed specifically for the 2015+ Subaru chassis, this harness ensures your aftermarket horns receive consistent power while maintaining a clean, OE-style engine bay appearance.
Each harness is constructed with high-grade automotive wire protected by a durable loom to withstand heat and moisture. The connectors are precision-molded to interface directly with the factory horn plug and Hella terminals, significantly reducing installation time and potential failure points.
- Complete plug-and-play installation with no wire cutting or splicing required
- Protective heat-shrink and loom for long-term weather resistance
- Optimized length for clean routing on 2015+ Subaru WRX/STI platforms
- Engineered for use with Hella Supertone and Sharptone horn kits
- Manufacturer Part Number: GRM040026
