So I am working with a H50 with lighting coil. As most of you know there is the plug that runs off the coil for running lights and it has three prongs that look like a small pyramid, one on top, two on the bottom, or vice versa depending on how you are looking at it. My guess is that the single prong on top is for a kill switch and the two on the bottom are for lights, can someone verify whether or not I am correct on that?
