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happy I got this far with just the small amount of material (out of date)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 The "r34 supplement manual" is insufficient, and out of
date.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.

Can I presume that you need circuit diagrams & troubleshooting procedures for a R34 GT-R and NOT a GT-T?

I only have info via a workshop manual for a RB25DET (and RB25DE).

I don't need trouble shooting procedures because I know what the trouble is .. just without an accurate
circuit diagram of the entire loom fixing it properly is difficult.

I need the wiring diagram referred to at the end of the list of technical documents attached here.
This screen grab came from "bookworks" an australian distributor of automotive books. They said
their distributor has no stock. Dead lead.

eg, here is the cover and price of the manuals for the 1998 model.

But 1999, 2000 .. screwed.
