The Ready-to-Run distributor is just that: feed 12 volts of ignition-on power to the coil and then hook up the three distributor wires. A weatherpack connector with pre-terminated leads is included. Hook the orange wire to the coil negative, the red wire to coil positive, and the black to ground. That’s it for wiring. Make sure to apply the supplied lube liberally to the camshaft gear drive to prevent wear on first startup.
