I bought this for the nilight 12in bar. It came in the same box and right on time. It easily connected to the light bar and into the engine. There is a lot of slack between the battery terminals and the bar, but it’s understandable if maybe you wanted to mount this on the back of your vehicle. I wish there was more slack between the relay and the switch, as having to go from the battery through the firewall and into the cabin requires sufficient length. I ended up getting rid of the circular switch that came with it and it’s complimentary connectors to replace it with my own rectangular rocket switch that fit better in the cabin. Overall good product. I’d advise to wrap electrical tape around the quick disconnect to prevent any weather wear.

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+
