Will this run down battery??** A: Seems a mix of the answers is the answer. Plug the extra white wire into the No. 6 terminal to make the light bar words light up when the switch is turned on. Plugging the extra red wire into the No. 6 terminal makes the light bar words always stay on. Find a wire that turns on when the ignition switch is turned on and connect it to No. 6 terminal to make the light bar words turn on with "key on". **Q: How long is the wire from the relay to the switch?** A: 6 to 8 feet **Q: The ad says it’s good for 300 watts. The instructions say 180 watts. I’m thinking the ad is wrong. 300 watts/12 volts is 25 amps.** A: The formatting of the specs in the instructions is a little confusing between the 16, 14, and 12 AWG, but it does state that the 14AWG max wattage is 300W. **Q: Will this harness work for 4-wheelers?** A: There should be no issue with using this kit with any 12 volt system. I installed 1 on a 2004 jeep wj, and it works flawlessly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Quality *by M***H on 6 March 2021* Quality excellent , for SUVs wiring length should be little longer otherwise good, almost took more than 45 days to get it but wait is worth ### ⭐⭐⭐⭐⭐ precio y material súper resistente *by J***E on 13 August 2025* un cable fuerte y resistente bien sellado mis respetos para el producto y el precio mucho mejor que otros cableados como los skp ### ⭐⭐⭐⭐⭐ Excellent kit *by S***T on 27 March 2022* Very quick and easy to install. The rocker switch works very well. It is only 3 months old for me but has had a lot of use and seems solid. The kit is built very good with good wiring and good parts. Survived the worst part of a Canadian winter with out any wires cracking. ## Frequently Bought Together - Nilight 10014W LED Light Bar Wiring Harness Kit 14AWG Heavy Duty 12V 5Pin Rocker Laser On Off Waterproof Switch Power Relay Blade Fuse-1 Lead, 2 Years Warranty - Nilight - 18003C-A 15Inch Triple Row Lights 216W 21600LM Flood Spot Combo Beam LED Light Bar Driving Boat Super Bright Led Off Road Trucks - Nilight 16AWG LED Light Bar Wiring Harness Kit 12V On/Off 2 Gang Rocker Switch Panel Power Relay Blade Fuse 5Pin Toggle Switches for Cars Boat ATV Trucks-4 Leads --- ## 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.us/products/253385935-10014w-led-light-bar-wiring-harness-kit-14awg-heavy-duty](https://www.desertcart.us/products/253385935-10014w-led-light-bar-wiring-harness-kit-14awg-heavy-duty) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-12*
