Factory 280Z Headlamp Wiring diagram

[TomoHawk]

Does anyone have a nice wiring diagram for the '78 280Z headlamp circuit, showing the switched grounds?  I had a "professional" install new headlamp connectors, and the dummy got the wires backward, like a new car has, with a common GROUND, Instead of the common hot wire and switched grounds.

 

I'd like to show a good wiring diagram, showing the switched grounds...

 

The diagram in the FSM is nicely drawn, but doesn't show the switched grounds, so you easily mistake that the headlamp switch is  switching the +12V feeds.the complete wiring diagram I have is apparently too complicated.

Hard to imagine a more clear circuit diagram than what is in the Body Electrical FSM section, page BE-9.

The top "summary" diagram gives you overall idea (including the switched grounds) and the lower diagram gives you every possible detail with wire colors and every involved connector. The "B" wire off of the combo switch (lower right) is the switched ground wire that the RB and RW wire connect with depending on dimmer switch position.

The guy  must've just went straight to the picture of the  switch at the bottom.
