HEI wiring question

Hello all, I have a 73 Duster 318 and I'm looking at replacing the mopar ignition with an E-coil and a 4 point ECU. My question is: If I delete all the old equipment, how do I wire the Ignition 1 and 2 to the coil. I understand most of the wiring, except the mopar "voltage regulator", can I delete this??? IF so, how?? I also have a relay, but I did not really know if I needed it or not.View attachment Mopar_Electronic_Ignition_diagram.jpg
