Way better and less expensive than building your own harness
Color: 14AWG-1 Lead
Went with a different switch but there’s no way I would ever do a led light install again without one of these. This makes it so much easier and straight forward than building your own harness. There’s quite a bit of extra wire when installing on an utv, but who cares?! For the price of all that comes with, you still save about $20! Besides, they’re universal and work for many vehicles including cars and trucks.

Used for a radiator fan manual on/off
Color: 14AWG-1 Lead
I used this to wire up my radiator fan on my 2000 Jeep Grand Cherokee 4.0. So far it seems alright. I have bought other kits and this kit came with just the right length of wiring, + I didn't need 2 sets of outputs like the other versions. The switch is a little cheap without feedback but for 10 bucks you aren't going to do any better making your own harness. I'm honestly surprised it powers the fan. These kits are insanely useful and from someone who has wired up lightbars, etc from scratch, just ease your troubles with this. By the time you pay for the neccessary components you will have spent more than this kit.

Nice kit
Color: 14AWG-1 Lead
This kit has everything you need for a nice clean installation! I used a different switch, but I liked the plug and play feature and only had to put on a couple of terminals, because I shortened the lead to the light bar! A+

Think about where your Battery is!
Color: 14AWG Wiring Harness -1 Lead
Best things about this kit are the quality, price and speed that I received it! One problem, my car's battery is on the passenger side. The only downside to this kit is that had to cut and add wiring to the lines going to the switch. I wish the kit had plugs on both long wiring bundles so they were interchangeable as I don't need the relay's wires to be as long as I need the switch's wires to be! I give the kit 5 stars anyway because for the price, you cannot go wrong here. I believe it is well-made and it worked out great for my fog lights! Very easy to install with instructions and color diagram!
