Complete motorcycle wiring system that includes auto cancelling lighting control module. This motorcycle wiring system includes pre-assembled harness, power module, and lighting control module. Use when you are not going to run any handlebar switches but still need switches to control the headlight, turn signals and horn. You will need to supply the switches for headlight, turn signals, and horn. Can be used to rewire your stock Harley Davidson, or to wire choppers, bobbers, customs or metric cruisers. The included lighting control module controls the operation of the front and rear turns signals and provides load equalization and auto cancelling. It also operates the rear turn signals as brake lights and running lights with one wire hook-up.
