Instrument cluster schematic

[Tractor Dave]

I'm attempting to make a bench tester to power up the S2 instrument cluster. I've been searching half the day, here and S2 Central but can't find what I need. Some of the links are broken or dead end
I have got hold of three good connector plugs, yellow, blue and white that fit the cluster. I just need to know which wires to connect to 12v and which to negative. I'm not trying to activate Speedo or revs, just power up lights, autocheck and mfa. Anyone help

Great idea hope you sort it such a pita swapping clocks in n out to see if things work

Have a look at the 3B instrument diags on S2 Central. You’ll need a Babelfish though

Actually the ABY Avant diags are there but not so easy to navigate to

I have a pdf file which I downloaded from erwin a long time ago for my aby avant. It contains pinouts for the blue and yellow connectors. I know it's not complete but it could be a little help

Thanks John.

Most helpful.

Confused why the heated rear window and a couple of other things go to the dash, but there we are

The pinouts for the blue and yellow connectors are in Bentley in the Electrical Systems - Instruments section.

They broadly agree with those listed in the link. :http://s2-audi.co.uk/tech_articles/instruments.htm

but Bentley lists:-

T26 pin 24 as the negative connection to the oil pressure warning light (so not a +ve supply)

T26a pin 24 as -ve connection to engine control indicator light
T26a pin 25 as -ve connection to seat belt warning light
T26a pin 26 as +ve connection to seat belt warning light

(T26 is the yellow connector, T26a is the blue connector)

Thanks John. I got that from Antsa

Is this pdf available as a download ?
