As you can see, this is a very simple step, you have to connect one of the ends directly to the receiver, any free channel will work. Make sure to connect positive and negative according to the marked + and - (positive and negative). All Traxxas Receivers have a small mark that tells you where positive, negative and signal wires should be connected. The best and easiest way is to follow the same alignment as the other cables.
In the other end, you have to connect the lights, the plug has 3 outputs, you can connect up to 3 sets of lights, if you purchased (or if it comes with your kit) the splitter, you can connect as many lights as you want, the controller is very powerfull and it can take up to 600 led lights simultaneously.
