Hy 696969, I've been away for a few days. Wire 10ga. from large connection on starter mechanical switch to battery connection on ignition switch. Run wire from ignition terminal on ignition switch to one side of ballast resistor, run two wires from other terminal on ballast resistor, one wire to the distributor, the other wire down to the small terminal on the starter mechanical switch, you have to purchase a new mechanical switch with the small terminal, tclederman posted a link above to the switch available at Napa, hope that helps.
