MSD 6al issues - bypass ballast resistor

Since the car was running before I made this update and the only change is MSD box (tests fine and is wired correctly), coil (tests out fine), and wires - the only thing I can think of is wires. I will check the resistance of all the wires and ensure the firing order is correct.

Can someone help with this question:

How do I determine which wire should be number 1 on the distributor cap to ensure that is correct? Set number 1 cylinder to TDC and the rotor should be pointing at 1? From there, the firing order is 18436572 in a clockwise order, right?
