Headlights, no low beams or one high, other low

Hi,

I can rebuild a carb, but stupid about electricity.

1978 280z, there are no low beams, and when kicked up to high beam, left is high beam, but right is low beam. I only kind of understand the wiring diagram, don't know which wire is the ground.
I assume power goes to the right light (R), and to the left light (RY) because they both trace back to the fuse box.
There are also two wires running between the lights, the RW and RB. I'm not sure exactly what they do, high and low beams? They both wind up at the combo switch.
And they all go through that junction box in the passenger side that's full of connectors. yikes...

My multimeter died, all I have now is a test light. Any help I can get would be greatly appreciated.

Thanks

Phil
