GrimmSpeed Hella Horn Wiring Harness Subaru WRX, STI, Forester & Legacy | Plug & Play | 040005

Video description

Make your Hella Horn installation quick, clean, and reliable with the GrimmSpeed Hella Horn Wiring Harness. Designed specifically for Subaru applications, this plug-and-play harness connects directly to your factory horn wiring, eliminating the need for complicated wiring, relays, or battery connections for most installations.

Built with automotive-grade 16-gauge wire, heat-shrink terminals, and protective wire sleeving, the GrimmSpeed harness delivers dependable performance while keeping your engine bay looking clean and organized.

Fitment:
Subaru Impreza / WRX / STI (2002-2014)
Subaru Legacy (2002-2015)
Subaru Outback (2002-2015)
Subaru Forester (2002-2015)

Features
- Plug-and-play OEM connector
- Automotive-grade 16-gauge wire
- Heat-shrink crimp terminals for reliable connections
- Protective wire sleeving for durability
- Fully pre-assembled wiring harness
- Compatible with GrimmSpeed BroTie and Hella Horn installations

Overview  

When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie, we have you covered. After some testing, we determined that the additional few dBs offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness using automotive relay, inline fuse and additional wiring directly to your battery. Fully pre-assembled, our simple harness will allow you to plug and play in seconds. Should your heart desire those last few ounces of ear-piercing goodness, our harness can also be adapted for use with a more complex relay harness. Diagrams for that configuration are included in our installation guide below.

Part #: 040005

Features:

  • Automotive Grade 16ga Wire - Minimal resistantce for maximum volume
  • Heat Shrink Terminals - Heat shrink, crimp-on therminals ensure a reliable connection
  • Protective Wire Sleeving - Clean black look, protects against abraision and stress
  • Plug-n-Play with OEM Harness - Installs and uninstalls in seconds

  • 2002-2014 Subaru Impreza, WRX and STI

Simplifies everything!

If you are doing your hella horns and have a hard time with wiring I'd HIGHLY recommend grabbing this kit. Made hooking up the hella horns super easy and the cables themselves were high quality from Grimm speed. Just grab the kit and save yourself some time and a headache.

Great wiring harness. Definitely worth the money over building your own. Braided cables and rubber covered connectors make this a great buy.

Some days not blonde for nothin'!

Had a bit of trouble getting it right, but once we got it, it was like "oh, man we made a mountain out of a molehill!" The 04 Outback setup was a bit different from my 15 Impreza, hence the issue we had.
