Hi all,
I don't suppose anyone has got one of these 1Z audi 80 wiring diagrams that then can email/photocopy&post? (would pay) Mine is a '94 model with 55pin ecu, I've only been able to find VW 68pin ecu diagrams searching online.
Would be very much appreciated
Thanks,
Brent

oh, my address is also brent%lang%20 at hotmail dot com (no %'s)

Hi Andy,
Unfortunately I'm still on the hunt :zx11: some people on the yard & 80-90 gave me some leads to try and chase, now I'm back from hols I'll get back on it...
may try Audi direct, VW have been good to me in the past - I drove my converted AAZ T25 round the workshop when I got it done as there was a lot of interest considering all the parts I was buying. Hoping for the same with the Audi lot, will post if successful... ;)
Regards,
Brent

Hurrah! many thanks to the legendary kenney for sending these hardcopies, i've scanned them for others to share...
:beerchug:
some translation from norwegian, but same-era coding works out. e.g. an 'N18' is an EGR whatever language you speak :D

oh well, i did try. lazy approach called for - link (sorry) http://www.brick-yard.co.uk/forum/victory-audi80-1z-tdi-94-55pin-ecu_topic61193.html
happy to answer any queries if you have them, but i'm not a major troubleshooter - connected things up as per the diagram and couldn't believe it worked first time :-)

Hi
One of the most time tasks with installing a stereo after market automobile, car radio, satellite radio, XM radio, car speakers, tweeters, car subwoofer, crossovers, audio equalizer, amplifier car, mobile amp, car amplifier, mp3 player, ipod or any car audio electronics is identifying the correct color car audio wires for the Audi A4, Audi A6, Audi A8, Audi Allroad, Audi S4, Audi S6, Audi S8, Audi RS4, Audi RS6, Audi RS8 or Audi TT.
Thanks
