## Customer Reviews

### ⭐⭐⭐⭐⭐ Great wiring harness
*by T***S on May 23, 2017*

Great harness for the price. This was super easy to install even without instructions, there was plenty of wire to route around the engine bay and inside of the cab. I wired the black ground wire to the relay metal tab to a bolt on the inside fender, worked perfect. I wish the lip on the on/off button was a bit wider so it would stay better in the dash. All together this is a great harness for wiring a single LED light bar. My bar is 180watts and this works just fine. I will buy another harness here when I wore my next lights. I live in Lake Tahoe California, so this will see all kinds of conditions from freezing snow to hot bumpy trails. Seems high quality and durable. I'll update if there is any issues. Thanks

### ⭐⭐⭐⭐⭐ Good Quality and Easy Hook Up
*by P***L on September 29, 2017*

I purchased a Eyourlife 20" bar light to hook up with this harness on my 2015 Polaris Ranger for a rear light. It was perfect for my needs. Hook up was straight forward. I drilled a 3/4 hole in the dash to mount the off/on switch. Harness came with fuse holder, fuse included and a 40amp relay. The light end of the wiring set had two female spade clips. I attached two male spade clips to the bar light for hook up. Plenty of wire for my hook up. The power hook up end had two eyelet spade on them. Very good kit and well worth the small amount of money it cost.

### ⭐⭐⭐⭐⭐ Worked for me but.....
*by T***S on September 5, 2017*

I gave this harness a 5 because it worked for me. It is also very well made, until you get to the switch. The caveat here is that if you are running lights on a full size truck, it most likely won't be long enough. It was just long enough on my Frontier. The problem is the short length of wire that attaches to your battery. This short length becomes important when trying to get the switch to reach inside the cab, unless you are going to run it straight through the firewall. The switch, while no more "cheapy" than most, does not have a mounting screw that slides over the back of it. It's one of those you just "push" into a hole. This leaves very little error in drilling the hole and it's made worse by no documentation to tell you what size the hole should be. I replaced it with a 9.00 switch from Auto Zone just to save myself the frustration. All told, a good, heavy wire that is well insulated but like everything else these days, they fut corners wherever they could.
