Instrument cluster schematic

Done


I have no way of testing the Rev counter or speedo but I can get just about everything else working on the bench which is very handy.

Are you thinking of offering a cluster repair service

[Tractor Dave]

Nearly there.

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

I'm pretty sure it's for background lighting. The grey / blue wire supplies lots of circuits to provide ambient lighting and it comes via the dimmer in the cluster.

Yes if you are willing to pay to access the erwin system. But the pinouts are listed in the link above

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

Is this pdf available as a download ?

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

Thanks John. I got that from Antsa

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)
