Questions about wiring harness for 1974 Options

[GeorgeKopf]

I'm going through my wiring harness with a fine tooth comb and I have a couple of questions.

In this picture:

I. What are these four connectors for? I think they are for the center console. Is that right?
II. Is this green wire for the parking brake switch?
III. Are the brown wires for the door switches and the black for the internal light.


What is this for? I believe it mounts somewhere under one of the seats and is used to connect the harness wires to the door switches. Where does it mount? Which accessories are connected through it?


The plastic connector holder on my turn signal switch is very brittle. I don't suppose there are any aftermarket replacements?



Lastly, where can I purchase all new grommets for the wiring harness?

Thanks.

George

Thank you Ian!

I'm having a bit of trouble reading the wiring diagram.

The wiring diagram has:
the door switches as brown/white (both wires to both switches?)
If both wires go to both switches, in parallel, won't both doors have to be open to break the circuit?
the parking brake as brown/yellow
the interior light as black/red

Do the door switches ground through the chassis?
Does the parking brake switch ground through the chassis?

Thanks.
