All,
I think I was able to resolve my wire identification question (using the FSM). From my combo switch to the Datsun side of the harness:
red/blue = blue
yellow/green = blue/white
yellow/black = blue/yellow
Based on the pinout provided in the swap thread(s), this would leave me with black = ground and blue/red = 12V+.
I have not successfully tested yet, but I will confirm once I do.
