Review: 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! Review: 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. ## Features - ※1 set of 12V Somaer horn relay wiring kit: the cable length is 64 inches, and up to two speakers can be connected (not including speakers). - ※Suitable for electric blasting horns installed on most grilles, the wiring harness can support 80W. - ※Plug-in connection, easy to install. - ※High-efficiency copper wire, heat-resistant, never melts, making the speaker more durable ,and 40A high-quality relay, high-efficiency protection circuit, prolong the life of your air horn - ※This is a SOMAER trademark brand product, we provide a 30-day money-back guarantee and a 1-year warranty with 100% support for our products.

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! ### ⭐⭐⭐⭐ Review *by A***. on 8 January 2022* 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. ### ⭐⭐⭐⭐⭐ Review *by A***4 on 24 August 2025* 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. ## Frequently Bought Together - Somaer 12V Horn Wiring Harness Relay Kit For Car Truck Grille Mount Blast Tone Horns(Horn Not Included) - Hella Stark Sound – 109.23.37 – Red Set 12 V High/Low Frequency Hella Super Tone Horn Set B 133, 12 volt - HELLA H31000001 Sharptone 12V High Tone / Low Tone Twin Horn Kit with Yellow Protective Grill, Includes Relay, 2 Horns --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/275521311-12v-horn-wiring-harness-kit-for-car-truck-grille-mount](https://www.desertcart.hr/products/275521311-12v-horn-wiring-harness-kit-for-car-truck-grille-mount) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-18*
