GrimmSpeed Hella Horn Wiring Harness for Select 2002-2015 Subaru Forester, WRX/STI, Legacy & Outback (GRM040005)
$36.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2002-2015 Subaru Forester, Impreza (including WRX and STI), Legacy, and Outback models.
Installing high-output aftermarket horns like Hella Supertones or Sharptones on your Subaru requires a more robust electrical connection than the factory wiring typically provides. The GrimmSpeed Hella Horn Wiring Harness (MPN GRM040005) provides a safe, plug-and-play solution that allows your horns to draw full power directly from the battery while utilizing your factory horn trigger. This ensures maximum volume and performance without taxing the sensitive OE electrical system.
This harness is engineered for long-term reliability in the harsh engine bay environment, featuring protected wiring and heat-sealed terminals. By using direct-fit connectors, it eliminates the need for cutting, stripping, or splicing into your vehicle's factory harness, making for a clean and reversible installation.
- Plug-and-play installation connects directly to Subaru factory horn triggers
- Relay-protected circuit for safe, high-amperage power delivery from the battery
- Protective wire loom and heat-sealed terminals for weather resistance
- Designed specifically for Hella Supertones, Sharptones, and similar aftermarket horn kits
- Manufacturer Part Number: GRM040005
