How Painless is it second time around

Starting on the electrical on my 67 Dart with a 360
I purchased the car as a roller now has a 71 la 360 with j heads 4 barrel
I will set it up as stock then add my msd and electronic ignition
I do have a stock wire harness from another v8 67 Dart but I like the idea of better wiring and connections and I will be adding a nice stereo heated power seats and other creature comforts
Heres my problem:
I have no documentation about harness. I dont know witch one it is

and need help
I will be able to post pictures as I go . this Dart has a complete head to tail Painless wire harness.
Doesnt look to tough some of it is marked but in the interest of time and maybe some frustration I need some help.
What should I look for beware of, Battery already wired to trunk from PO
Do I start at Dizzy and go from there?
thank you for all who put there .02 cents in!:notworth:
