I spent a lot of time on this and have boiled down my problem to just
a few annotated pictures, and a bonus question thrown in. I'm really
happy I got this far with just the small amount of material (out of date)
available.

original problem: 4wd, a-lsd and abs lights all ON. No error code.
Consult can't scan the unit to get an error code .. because ..

basically i need to know how the line I have indicated can have no power..
where is the line I marked (green with red stripe) that goes into the relay
indicated, where is it coming from that it has no power?

Yes all fuses checked..

Someone must have a recent circuit diagram of R34s. I've tried three
skyline tuners and none of them do. The manual exists and is in
english/japanese .. The "r34 supplement manual" is insufficient, and out of
date. It simply indicates pin 111 goes to IGN, but doesn't show the relay
I marked.

please help so i don't do a bodgy fix like running a fused 12v line in
from somewhere else. That totally fixes the problem. But is very unsatisfying.
