12V Horn Wiring Harness Relay Kit For Car Truck Grille Mount Blast Tone Horns(Horn Not Included)

I never would've bought a premade harness before for horns, always preferring to make my own. But now I am old lol. This was fairly priced and made it easy to put in horns into my wife's car on Christmas day.

Great quality for the price. Easy install. Worked great for my Hyundai converting from the wimpy single horn to two more powerful horns.

Works but I had to use many additional wires to connect to ground, and battery black terminal. Because of that the relay went over vs under the car. I wish the length from relay to battery terminal was at least 3ft.

This thing makes putting in an aftermarket horn a snap. Sure, I could get a relay and wire it up, but not as inexpensively as just buying one of these. The included wiring diagram is a nice touch too. I only needed to clip off a couple of the fittings on it for power and ground, and after that, it wa just plug and play. It's very nicely put together and the wire lengths were good with room to spare. I would recommend this to a friend and buy again when the need arises.

I have this harness connected to my hella horn set and couldn't be happier wires were easy to run. They are thick enough gauge to produce proper amount of volts to the horns. Relay was easy to conceal. Id say for taking a beating in my engine bay next to warm radiator and running to the horns near grille facing cold winter they are pretty well built . And for the price definitely worth it. Id buy again

I know how to install horns and radios and wire vehicles pretty well and decided to skip a step and have a premade wiring harness this one time… But this turned into a massive nightmare. After installing the wiring harness within two weeks, the horns went one night on their own and burn out one of the two Hella horns…the cheap made relay from China in the package also failed. Tested the relay in the relay is no longer operating from a bench test. Also check the wiring harness, and the wiring harness has no contact in one of the leads and just complete absolute pile of crap. Save your money and don’t lose $100 with a horns on some cheap wiring harness .

Not bad but not great, decent gauge wire and well protected with loom, but weird lengths… and relay was not wired how I would expect so if you’re looking for plug and play I would look elsewhere

Good value for the money. I could have made my own harness, but it wouldn't have been as nice as this and would have cost more to make. Ring connector for the battery +, Ring terminal neg to the chassis ground, female spade lugs for the Hella Horns, male spade lug for the relay +, and wire looms covering all the wires. The male neg spade lug is for the relay. This one through me. All the grounds have continuity to each other, and the ring lug connects to chassis ground, but the one male spade lug neg must be connected to ground or the relay won't work. This one you can also connect to chassis ground.
