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...
Bundle 1 is self explanatory with big 55pin connector to the ECU.
Bundle 2 requires some explanation - lets look at the branches as they appear starting from the bulkhead grommet.
2.1 - F75 (hydraulic oil level switch), T8e and T8f - Note T8f is denoted '1' with a sticker and T8e denoted '2'
2.2 We have quite a lot here -
T4g brown - input side to POS for cyls 1-2-3
T4n black - input side to POS for cyls 4 & 5
T3k white - fused power to coils 1-2-3
T3aa white - fused power to coils 4 & 5
T3o blue - to G66 via firewall plug panel (FPP) - knock 1
T3n green - to G61 via FPP - knock 2
G69/F60 - Throttly body
T3l black - to G4 via FPP - Crank reference
T3m grey - to G28 via FPP - Crank speed
plus a thicker branch at the same location containing
N80 blue (EVAP)
G62 white (Coolant Temp Sensor at rear of head)
N71 grey (ISV)
Manifold earth eyelets
G42 black (IAT on inlet manifold)
5 x injectors in the order you'd expect with Cyl #1 nearest the last connector in this branch for G40 (CMP)
2.3 is the 3rd branch with Z19 & G39 for lambda
2.4 is F21 (spades) and F34 (2-pin grey) for hydraulic servo pressure and brake fluid levels into Autocheck
2.5 is a special branch for G70 (MAF)
2.6 is a grey 2-pin T2aw - which is handoff point for a 2-wire loom extension to the WGFV... This circular connector slots into a clip on the left chassis leg below the MAF hose.
2.7 is T1 (a white spade) for the starter solenoid feed - black/red wire here
2.8 is the last item on the branch as a hooded black wired eyelet - with no denomination on the schematics - it is for the oil temperature sensor - down near the oil pump... This connects to the centre console guage.
T2s in that 3rd main branch stays inside the cabin - it goes to the centre console where it connects to the oil temp and pressure guages.

My phone corrupted all of last nights connector pics - bahstid - so patience please while I do it all again... Will be worth the wait I promise with LOTS of info to help folk get their heads around this one.
Solved the single brown/yellow wire mystery - that isn't strictly part of ABY loom - its from a car with manual aircon... Tracks to pin 87k on the fusepanel at Relay #6.

Brian - that is equally plausible... perhaps more so actually... I am in the middle of creating the mother of all ABY wiring guides here !
I'm excited to see that guide.
I have a bently manual for my coupe, it has the wiring diagrams. I have always thought I had a decent knowledge of electronics, however I don't really understand the layout. Is there a guide to understanding the diagrams?
