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

Worked fine. MUCH faster and easier than building my own. Seems like pretty good quality and there was plenty of wire available to run it where I needed, possibly even too much. I may get in there and clean that up sometime.

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.

Good quality easy installation. No any issues

The relay is in all a good unit , The only issue I had was the shorter of the two horn leads could have be longer. Also the ground wire. Work well otherwise.

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

The instructions wasn’t as good as I thought they would be, I’m not an electrician so I haven’t figured it out yet, anyway too send me better instructions from the seller where I can do my air horns please ?

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 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.

These worked great with the Hella Sharptone horns on my Toyota. Many comments here complain that the negative battery wire is a bit short but you only need to ground it to any bare metal on the chassis. Shipping only took a couple days too!

Took a long time to arrive but I believe it had to come from the USA. Not installed yet but have tested and works fine. A simple kit but one which does what I need. Will be a simple installation. My classic Rover’s horns are weak due to no relays and relying on current passing through the 45 year old horn switch. This kit should solve that, providing for power directly to the horns via the relay.

Great item, some of the connectors are cheap and can slide off the wire but the whole thing is still great and functions!

Good kit. Instructions were basic but got the job done.

I bought a Somaer 12v wiring harness to install a set of Hella horns into a Fiat 500. Because I was worried about current drain on the original wiring harness, and I was installing two horns to replace the original one horn, I wanted to use a harness that was independently powered, fused and relayed. This harness saved me a lot of trouble and the quality of the kit and connections is much better than I could have done myself. Just had to modify two clips to match & fit the Fiat harness that acts as the relay ‘trigger’. Not to mention that it was cheaper than parts alone and saved me lots of time, which I value greatly. It should be called the Super 12v Horn Wiring Harness. Fabulous. Good job!
