This made the Hella horn install super easy. I have no wiring experience so I wanted to get a fool proof option. This did it. Highly recommended.

Nice braided jacket to protect wires, and quality connectors. Hides well behind the grill. Made install super easy! A little expensive, but It looks better than wire loom and or E-Tape!

The quality in the build is awesome. Thanks Grimmspeed for making little things so easy to install. Used the wiring harness to install a set Hella 'bro' Horns on my 2005 WRX Wagon.

No nonsense plug and play. Made installing the horns a breeze. Top notch quality can't beat it.

it is a great product from grimmspeed but i would still highly recommend wiring up your relay with horns just this plug and play half of wiring will not be enough to keep horns going in longevity. as i am coming from experience and reading forums eventually your horns and or fuses will burn/ short circuit because the supertone horns require more power than the stock horns do.

Bought this to wire up some Hella supertones on my 2015 Forester XT. A very nice and quality harness here - braided and sealed, super top quality. Terminals fit right onto the supertone blades, nice. I had to cut the blue cover off of the blade which connects to the stock horn plug to make the connection, but just sealed it up with a large-diameter peice of shrink tubing. Now honestly, on the 2014+ Forester XT there isn't much need for this harness. If you remove the grille (bumper removal not required, just some dexterity and patience) you can make some short jumper wires with blade terminal ends to run from the two stock wiring plugs to the horns, as well as some short ground wires. A Relay are stock on the forester, you don't need to install the one that comes with the supertones. So I reckon you'd be better off making the connections yourself - your wiring won't be as flash as the GS harness, but for the FXT it doesn't really need to be in my opinion. Great product though if you're not very inclined to DIY!!!!

This was so worth it because it uses the oem plug for the stock horn and the only part I had problem with it and the grimspeed bracket it that it didn't have the nuts for the horn themselves and the grounding wires bolt

Good Quality, But this Product does not fit my 2015 FXT Stock connection. I need to cut the plastic part off and wrap it with tape to secure it to stock horn ticker head.
