Hi, I am looking to get rid of some of the wiring on my bike that I don't need. I don't use any lights, horn, computer is toast, etc. I'm looking to keep just the basics for the CDI and spark. I have 3 wires that go to the coil and voltage regulator and am wondering if I need to keep them all. There is one for the coil, one from the AC that goes into the voltage regulator which I don't think I need, and a ground which I am unsure about. Does anyone know if this is a ground that is needed for the CDI or is it just for the accessories? The coil has a separate ground.
