ABY Wiring Harness Help/Identification

My piece of **** Nokia phone is dying so photos are coming slow here...

So lets start with the big grommet at the bulkhead where we can see the main strands of the ABY loom... We have five branches at this point -

1 - To the ECU - wrapped in yellow tape

2 - The heavy insulated section into the engine bay (details to follow)

3 - A skinny bundle that connects to brown 2-pin plug T2s (more on that later)

4 - Another skinny bundle, yellow wrapped, to the coding plug (T6d) and pressure sensor (F96)

5 - Big yellow bundle to the fusebox with a mass of spaghetti at the end (details to follow)

OK - I'll start on this tonite.... be advised that SOME wire colours change with model years and S2/RS2 variant so it won't be 100% perfect for all applications...

I have a spare fusebox here I can photo and assist if required.

Again anything you are willing to photograph and post will be quite welcomed.

I have an ABY loom here that I laboriously cleaned and labelled all connectors if it helps here.

YEAH! that would help VERY MUCH, I would love pictures of the whole thing with labels, of course if you have the time and desire, i know it would help me out, and from the looks of it, a few others.

FOrtunately I have time on my hands tonite so thats a bonus... Some answers above seem OK - but not 100% on some of them... For the fusebox connections - you need to know how to navigate your way on the back of the fusebox... ensures you get the right locations to activate fuel pump and other little details.

Passenger side pillar, just above the earth point to the left of the glovebox.

On an ABY coupe, where is the Altitude sensor mounted? does it matter?

[Acidburn]

In the coupe 10v/20v/3b they are normally in the footwell, aby afaik fusebox. They can be where you want them, whatevers easiest for you that lets you access them.

[Ruffiano]

so in the ABY coupes, are the diagnostic plugs in the fuse box? In my coupe quattro they are in the drivers footwell...

Ive got a white plug o my 10V and a black one on my 3B for Aux dials, dont know how much help that is here but thought id mention it anyway, certainly the right shaped plug for that.

[Acidburn]

Aux dials has a white plug.

On the wiring diagrams it's listed as "coding plug not used"

Hmmm I've had a few with different colour plugs black and white, i'll have a look at the *yet another loom* in the back of my a4 in a bit and see what colour is on that.
