Need help on wiring

So i am trying to piece together my 1967 dart with a 383, i'm having trouble with my wiring. I recently bought a HEI distributor for my car and it came with the distributor, ignition module, ignition coil, and i believe its called a ballast resistor. i bolted my ignition module down and wired it to the distributor. Well, i was reading up and it says the the green wire on the wiring doesnt need to be hooked up to anything. I grounded it to my car. Then i read up that I dont even need a ballast resistor, can someone explain to me how i would properly wire it? thank you, i am using switches for ignition, and a push switch to start. Thank you, any help would be appreciated.
