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 .

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.

Switch it on!!!
Worked perfectly for the new light bar on my truck, good quality and looks, plenty long enough, and basic to install and use. I liked that the wires were protected and also helped with fishing the wire through tight spaces. Highly recommend and fair price.

Very nice quality. Worked great for 2002 Silverado fog lights
Best bang for your buck! Really nice fog light wiring kit. Used to add fog lights to my buddies 2002 Silverado. Everything in the kit is nice quality. The relay works great, I kept it in an area that will stay dry. Highly recommended this kit for an affordable fog light install. I’ve read people use these for electric radiator fans as well. The quality of wire, sheathing and relay is what really sold me on this kit.

A must have when installing auxiliary driving/fog lights.
I installed driving/fog lights on my Yamaha XMAX 300. I was told I needed a “relay” so I wouldn’t overload my wiring. My cousin said that he had spare parts and could make it work. I wanted a complete harness that had everything all in one new package and didn’t need any cobbling together. Enter this 2 lead harness with relay, fuse, on/off switch plus a well wrapped protected harness. I had two lights, hence the 2 lead selection, if you only have one light or one light bar then a one lead harness is what you want. I had to drill a hole in my faring to mount the push button lighted on/off switch. I used a step bit and took my time and it fit perfectly. Very happy with this product!

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.

Great quality, lots of features at this price point.
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.
