LED lights may be popular in vehicles modifications these days. Many enthusiasts also prefer to do the modifications themselves. When they do the modifications, they will always come across a big problem—how to wire up the light? Some may just directly prolong the wiring of the light and straightly connect the lights to the electric system of the vehicle. This may be a way to fix the problem, but they may ignore the potential danger that may occur. The best way to deal with the problem we mentioned above is to add some wiring harness for the lights.

The wiring of the harness set is not difficult, but some people do not know which wire goes to where. This video below guides you how to install a relay harness for LED work lights, LED driving lights, LED light bars or other LED applications. In this video we will wire up the Auxbeam 7 inch Led light bars. Before we get to start, there are two components in the relay harness set, the actual relay and the switch. So when you remove the tie binding everything together, you will see the wires are pretty long.

So to start, we are going to connect the Led light bar first. For the relay, connect the black wire to the battery negative, and the red wire to the battery positive. It should be connected like these. Then for connecting to the ACC, the red wire also goes to the battery positive and the black wire to the battery negative. Finally, it should be install like this. If you see the led indicator on the switch is red, it means the wiring is successful. Press the button, and the Led indicator lights up green, your led light will light up as well.
