I'm working with a G180 engine that was dropped into a 72 Datsun 620 pickup.
I do not have any of the original wiring for the charging system and would like some help, The wiring diagram posted below wasn't much help.
I purchased this one to replace the bad 620 regulator:

Here is what I think right now:
White - B on the Alt. and Battery.
Blue - Charge Lamp.
Yellow - 'N' terminal on the alt. (small wire)
Red - 'F' terminal on the alt (small wire)
Green - Ignition.
Black - Ground
