wiring harness, dyna,

Thanks from all the help from z1 enterprises. I am pretty sure I have decided to go with the dyna s 2000 full ignition system. The dyna tech says that the system is a standalone system and will use none of the factory wiring harness. With this said, I have decided to try to wire my own wiring harness. The only necessities i can think of from the factory wiring harness are the charging system, and brake light. Does this seem feezable?

The plan is to wire the brake light, and wiring harness myself. Has anyone tried this before? What all is part of the charging system? The fewest wires and simplist is my goal!

???, Steell, anyone?
