I'm up to 22 technicolor pages already... Had to take a break from it there - my brain was starting to hurt. Should finish it tonight - keeps me out of mischief

Sounds like your putting some big time into this. I for one will owe you for this, will make life a lot easier when i get to this stage

I need it to be as good as I can make it... trust me - will be worth the wait !
34 pages and counting - might hit 50 before its all done - 50 pages I mean - not my age

i am in this boat also. hopefully i can have my ABY harness here soon. :-)

Well I was working at this into the small hours last night... I've decided to make the information a lot more modular. Here is the first section pretty much complete - it serves as a primer to navigating your way round the schematics & understanding where everything is.

The ABY loom info is going to take me another night - should be worth the wait.

Then I'll do all the fitment locations.

Followed by soup to nuts on fuses & relays in due course.

ALL of this info will wind up on S2central.net - so think of this as a sneak preview.

Comments / Suggestions greatly received.

Now thats a handy little guide, i never knew how to interpret T10a/5, you learn something new every day

I like! I feel like I have a clue as to what I'm looking at, and what i'm looking for!

**S2central.net** · 2 August 2009, 00:14

OK - it is done... 51 pages of fun and ~30MBytes... uploading somewhere now !

**S2central.net** · 2 August 2009, 00:30

Got it down to 6MB in PDF format - available here - http://www.s2central.net/S2_Schematics/ABY_Wiring.pdf

I'll integrate it into the schematic pages on my site soon - but there's the raw data... I'm rather pleased with it as this didn't exist 36hrs ago - but it has taken most of that time to compile it.

Let me know any comments or suggestions please !

this is amazing!!!

THANKS!!!

paul i just finished going through it, this is fabulous! you just took all the guessing work out of my project! only suggestion i could think of is moving the secondary engine wiring harness to be with the rest of the "under hood" stuff and put the interior stuff last... Amazing work!!!

So another quick question, I received this with my wiring harness, but have absolutely no idea what it is for or where it would go.

Simple blue wire with spade connectors on both sides, however it also has the "under hood" style wire cover

Not 100% sure on that one - its not specific to ABY loom - pretty sure it is the blue wire coming from the alternator (only presents ~14V when engine is running) - Track 7 on that schematic sheet C50 - goes to T10a - which will be the yellow multipin block in the auxiliary wiring panel. I'll add this to the docs - thanks for spotting it.

That is nothing short of MAGNIFICENT! There are obviously a LOT of hours in that.

Lovely work Paul.

Cheers,
