I use a "log" book whenever I mess with wiring--small drawing, red wire goes here, black there, or black to green or whatever the combo....helps a lot when putting something back together and if you run new wire then you make a new drawing showing the connections.
Color coded amp rated quick-connects are truly the way to go if you do have to ever remove a part, alt ,starter, lights, gauges, or the engine itself--keep a record for backup of what each color is for in your "log" book--pull the part or piece or engine--when it goes back together just plug color to color.
Used this type of system for years on the electrics on boats.
Sounds like you are the right track with your alt connections
