When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie Bracket, we have you covered. Don’t stress yourself with trying to make a Hella horn harness from scratch when we offer a simple pre-assembled, OEM-quality harness that will allow you to plug and play in seconds.
You’ll notice our harness does not incorporate the Hella-provided relay as standard. 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 the relay, inline fuse and additional wiring directly to your battery. Should your heart desire those last few ounces of dBs, our harness can be adapted for use with a more complex relay harness.

Took five minutes and got rid of the relay that was always going bad! Can’t recommend enough.
This kit was out of stock and I was impatient and got a universal kit. I went through the trouble of installing the universal kit with wiring through the car and booking up to the battery. It was more complicated than it needed to be and failed after a heavy rainstorm got it wet. Finally got this wiring kit. Soooo easy. Don’t look elsewhere, get this kit. It’s the one you want.
Super easy to use/install. Pretty much plug and play. Highly recommend!
This is the perfect pre-made wiring solution. Easy to install and high quality. So glad I found this product as I was struggling with products I found elsewhere. This is the one that worked and it was just what I needed.
The most basic products always surprise me. The way the cords are braided and how simple the connections are. This is by far one of the favorite purchases I've made with GrimmSpeed. I love it. GrimmSpeed knows how to make and sell their products.
Super easy plug and play wiring harness that makes life so much quicker to install your Hella Horns on your Impreza. Have the same harness on my '07 Impreza and '18 Impreza. The install was so much easier and cleaner and you cant tell that there is even a harness there.
So easy, even I could do it
This install couldn't be any easier.
Comes with everything you need simple plug and play works great with the BroTie
Great product! Very easy to use, plug and play. I have no knowledge in car whatsoever and I’m able to put it together in minutes!
Perfect fit high quality product easy installation im loving this wire harness for my Subaru Wrx thanks again Grimm speed
I was glad that I listened to other reviews saying the harness was a must-have addition to the horns and bracket. Having a plug-n-play harness allowed me to install the new horn set in about 10 minutes once the bumper was off. I highly recommend this if you are buying the hella horns.
This was the simplest mod, wiring harness that I've put on a Subie! Loved the simplicity and packaging.
Well-constructed with quality materials. The harness comes in contact with A/C condenser on '02-'07 WRX if using the Red Hella Horns (not the yellow ones) so you have to bend them out of the way. Otherwise they do save a lot of time from needing to build your own harness.
Constructed well, and makes the install of Hella horns that much easier. 10/10 would purchase again.
I bought the Perrin hella horns kit and the bracket but had no idea that I needed a wiring harness, I'm so glad that Grimmspeed had the harness by its self for me to get. I have no idea how to electrical stuff but this harness made it super easy. Thanks Grimmspeed!
this harness is what my great grandmother would call the "bee's knees." it's what my grandmother would call "blockbuster." my mom would call it "groovy." i say it's "wicked." and i'm sure the little neighbor kid down the street would call it "phat." but no matter who calls it what, this harness allows you to hook up to horns with no additional power source. it's wrapped nicely and made with quality. i highly recommend.
Excellent quality
I purchased this harness to replace the system that came with my Hella Horns when I bought the car. It had a relay and my horns barely worked. I rewired the horns with this harness in under 5 minutes and everything worked flawlessly. Very well-made wiring too. I would definitely recommend this for anyone wanting debating on what wiring to purchase.
Excellent quality plugs into connectors very easy
This is a well-made wiring is that comes with everything you need to install your Hella SuperTone horns. All of the connections are well-made and sealed with a plastic sleeve to keep debris and dirt out of your connector. All of the wires are wrapped with an extra heat shield to keep them from building should they touch something hot. All in all this is a great product and helps to make the installation of aftermarket horn's simple and easy. Great job Grimmspeed !!!
This harness is great! Main thing that I loved about this harness is that it's pretty much "plug n play. " The install is super easy and it is not necessary to have to route the cable up to your battery. I highly recommend this harness for your hella horns.
I can't believe I didn't uses this handless earlier. So easy and no need to mount a relay!
Super easy install, I just wish the power wire was one foot longer, I had to extend it to reach the horn under the passenger headlight. Subaru switched the horn locations on the WRX and the impreza.
5/5!
Yes, I could have wired up my own solution and it would have been fine. But, I am getting to the point where it is easier to find a good product instead. This is it! Very well made and the protective sheath along with the sealed ends make this a no brainer. Good job Grimmspeed on this one!
Ordered this so that I would have a reliable harness for my horns that I ordered from Ebay. Couldn't be happier with this product. Thank you guys
