    Great Simple Wiring Kit.

    Easy to install, simply wiring kit. Wish a template was included for switch mounting, but was able to use rubber gasket as a guide.

    Works good.

    So simple a cave man could do it.....

    Purchased to go with my Nilight 37 in LED light Bar. Very pleased with the harness and switch. The harness comes with an in - line fuse and relay. Super easy to install with the only thing I needed was electrical type to provide additional weatherproofing to one required connection and a few zip ties. All connectors and spare fuses provided along with simple to follow instructions for those not familiar with 12 v wiring. The wiring length is enough for most any configuration / location of switch.

    Awesome Product

    Super high quality in every bit of this package! It comes with everything needed and more. It is very easy to install and I loved the look of it. Not the cheapest one on the market but you get what you pay for and they held up their end! Installed on 4th gen 4Runner 2007.

    Don't believe the 1 star reviews!!

    After seeing so many 1 star reviews for this exact thing I figured I'd better say something. So this is the exact thing that everyone is complaining about right?? Well look close..... I connected the wiring to the switch wrong (bad reviews don't show how they wired the switch connector and you can see white to black and visa versa on the connectorto the right). Not sure how I messed that up....lol but the point is I messed it up. The product is great....when it melts/starts on fire.....yeah 100% user error!! C'mon guys, be 100 in your reviews.

    Where is your battery

    The length of wire from relay to output is long. I needed to go from the passenger side battery to the drivers side tow hook and then out to a LED bar on a snow plow. Plenty of wire.From the battery on the passenger side front of an Excursion the wire from the relay to the switch was about 6 feet too short. This was trying to run it through the firewall on the drivers side to a switch mount above and to the right of the accelerator pedal. Contacted Nilight to see if they sold an extension jumper and they do not. I bought 10 feet of 20AWG wire (red, white and black) and the proper connectors along with some heat shrink tubing and made my own jumper. The connectors aren't necessary as someone could simply cut off the included connectors and add in the wire. I think any full sized truck with the battery on the front passenger side would need extra wire from the relay to the switch.
