GrimmSpeed Hella Horn Wiring Harness 2015-2021 WRX/STI/BRZ

When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie, GrimmSpeed has you covered.

Note that this harness plugs directly into your stock horn wiring harness. After some testing, GrimmSpeed 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, the GrimmSpeed harness will allow you to plug and play in seconds. Should your heart desire those last few ounces of ear-piercing goodness, the GrimmSpeed horn harness can also be adapted for use with a more complex relay arrangement. 

Hella horns and mounting bracket not included; sold separately.

Fits all 2015-2021 Subaru WRX and WRX STI, plus 2013-2021 BRZ/FR-S/Toyota 86
