GrimmSpeed Hella Horn Harness - Subaru WRX (VB)
Wiring up a set of Hella Horns usually means splicing into the factory harness and hoping your connections hold up. GrimmSpeed builds this harness to remove that guesswork entirely, giving Subaru WRX owners a proper plug and play solution built to the same standard as its brackets and other electrical components.
This listing covers the 2022–2025 Subaru WRX (VB). The harness connects directly to the factory horn plug and existing horn mounting bolt, with no cutting or splicing required to run Hella Horns on your VB.
Key Features
- 16-gauge wiring for reliable current delivery
- OEM-style connectors for a factory fit plug and play install
- Braided loom and shrink wrap for long term protection against heat and abrasion
