I built my own wiring harness. The ignition came with all the wires I needed. All I had to do is hookup head/tail lights, brake light and run power to the coils and ignition. I have no instrumentation or dash lights to deal with. Here is the wiring diagram. Mine is kick start only so there is no starter circuit. But you won't need one if you are using a solenoid end cap w/ a button.
