Engine Wire Harness and HEI conversion

[ACK]

I'm making the jump to a HEI distributor. I've been reading up and want to confirm I did my homework right. Attached is a pic of my wiring harness ('64 C10 with 4.1L) and here's my questions:

1. Did I identify the wires on the harness correctly?
2. Can I replace the white resistor wire with multi-strand heat/oil/gas resistant 12-gauge and run it straight to the HEI as my ignition power wire?
3. Any reason to keep the dark blue wire?

As a side, my resistor wire runs straight from the harness to the starter. Thanks!
