Wiring identification preference?

KISS. Keep it simple stupid. This isn't an airplane where all of the wiring is the same color, then needs to be labeled. Arguing will ensue, buy factory replacement harnesses, why would you want to patch up 50 year old plus harnesses if you are worrying about fires?
New wiring will end up exactly where it needs to go, color coded to a FSM.
Evans or M &H wiring.
