Highly recommended!
Excellent wiring harness, very durable and easy to install. The rocker switch, relay, and fuse feel high quality and work perfectly with my LED light bar. Wiring is clean, well-protected, and handled 12V power without any issues. Great value for trucks, ATVs, and off-road lights.

Simple installation -Used to Wire Cooling Fan on RZR
This wiring harness kit is a fantastic solution for anyone looking to install aftermarket lighting or other 12V accessories. High-Quality Materials: Right out of the box, you can tell that this wiring harness is made from high-quality materials. The nylon wiring is thick, durable, and well-insulated, giving me confidence that it will stand up to the elements and regular use. The connectors and relay are also solid and well-built, ensuring a secure and reliable connection. Easy to Install: The installation process was a breeze, even for someone with only basic electrical knowledge. The kit comes with everything you need, including clear instructions. The pre-wired relay and fuse make it super easy to connect the harness to the battery, switch, and light bar. The included rock switch is also a nice touch—it fits perfectly in my dashboard and has a solid, tactile feel when toggled on and off. This wiring harness is versatile and can be used for various 12V applications beyond just light bars and fog lights. Whether you’re installing auxiliary lights, air compressors, or other accessories, this kit has you covered. The single lead design simplifies the installation process and keeps the wiring neat and organized.

High quality and low price, I'm sold
Excellent quality wiring harness with nice relay, fuse holder and LED switch. Wires are jacketed and terminate in insulated female flat disconnects. Theres plenty of length for each leg of the harness (switch easily reaches dash or panel), relay has mounting tab and power/ground wires have ring terminals. The 2 leads are bundled together until the final 3 ft or so, so it will easily reach the pair of lights or some condenser fans like I did. I ordered more for installing lights on other vehicles. This harness cost a third of the price of the last one I got with all of the quality and utility of the more expensive unit. Just like the Nilight LED fixtures; their harnesses are the obvious choice for quality and price. I'm a convert from the much more well-known and pricey brands.

No complaints so far
I’ve used this harness several times and at this point I feel like I have to recommend it. No complaints on the wires, relay, or loom. The gauge of wires are adequate enough for what I need it for. One harness is used for my aux fan that I use almost non stop in summer days above 102degrees. The second one I used for my fog lights, I run just about every night. No melted wires. No popping fuses and no blown relays . It’s cool they’re clear but not something I care about, however they function normal. The length is good btw for a 98 obs Chevy. It reaches the front bumper and can reach all the way to the dash. The only complaint I may have is the ground wire not being long like I would like. But even then it’s not a big deal since this harness is multi purpose. Recommend it if anybody needs a harness .

Perfect harness at a great price
Works as it should and more than enough length for fog lights. Will buy again

Way better than expected at this price level. wires are encased in a braid, so easy to route and zip tie. All the ends where there are connectors are shrinkwrapped. Has a disconnect near the switch so you can add in an extension - which I didn't need as there were miles of length. However I did use this; I disconnected the switch and a short length of the wiring which allowed me to run this from the cab through the firewall which was way easier than running it the other way - truing to get the switch from the engine through the firewall into the cab would've taken some gymnastics and frustration. This way I just reached down into the engine compartment, grabbed the end and reconnected it. The end for the lights have female wiring connectors. The kit comes with male connectors and shrink wrap for the lights - a very thoughtful addition. Saved me a trip to the shop for parts. overall very pleased with this set, particularly at this price point.
