To wire a ballast resistor, run a wire from + on the ignition, to the ballast resistor, then to the points in the distributor. For the bypass, wire it to the terminal on the starter solenoid farthest away from the engine, then connect the other end of the wire somewhere between the distributor and the ballast resistor. If you have a ballast resistor, want a bypass, but don't have the terminal, the solenoid side of the wire can be connected to the terminal that goes to the starter or to the wire that comes from the ignition to the solenoid, but you'll have to use a diode or rectifier in that wire.
