Im really not sure if I can give a full 5 stars but I can give an honest 4 stars with explanation. This wiring harness can easily be fixed to protect the wires from shorting by adding a smaller fuse than what is provided with the product. The relay is massively over sized at 40A, which is a good thing but the fuse is over sized beyond the wire gauge used, which is a bad thing but is very easily changed. It comes with a 30A fuse and I think 15A would be he biggest. The simple math on it is pretty easy. If they are saying it will do 180W, then its 180W/12V = 15A. The main power wires that have been used in the harness are 16ga and after looking a few places on DC wire gauge vs Amps really 16ga stranded copper wire should not exceed 15A. As advertised with the harness showing the two 18W spot lights, those only need 3A. In the advertised scenerio, this harness is built well above demand. If somebody throws one of these 54 inch roof top lights on it, its going to short out the wires, burning them up. I will be putting a 120W on it and will put a 10A fuse to match the light. ### ⭐⭐⭐⭐⭐ This simplifies your light installation *by C***L on Reviewed in the United States on September 3, 2018* I got this to install the AutoSonic light light bar. Normally when I install lights I just piece together all the parts. This kit was cheaper for me than to buy everything individually so I gave it a shot.Overall it’s nice to have everything ready to go. As some other have pointined out some of the wires are on the shorter side. This wasn’t a problem for me as I had some wire on hand and just extended them to the length I needed.The parts all seem to be decent quality. I could see how the people who are confused with relays would really benifit from this as it takes virtually all the required knowledge of electronics out of the way.In summary, I’m happy I bought it, I felt it was worth what I paid, and would buy another one the next time I need to install lights. ### ⭐⭐ Not laid out well. *by T***D on Reviewed in the United States on January 18, 2019* As I have wired in several sets of auxiliary lights in the past I came across this kit and was definitely excited. Looks good and it comes with 3 of the key items for wiring a set of lights. In less than 5 minutes of opening the wiring harness kit I saw something wasn’t right. There was no trigger switch wire, the trigger switch wire was wired with the power source coming in. Grounds were crossed. I will be using the kit as I have already unboxed one and rewirded it. Im not sure if it is good for just a light or a winch, but it will not suit for a car/truck. No way for it to turn off with the rest of your vehicle.
