This has probably been done to death before, but a search of the archives didn't help, so here goes...

I have an 89 Audi 90 and the DPO has been in there with a set of cutters. I need to re-wire ISO connectors to suit a Kenwood head unit. Anyone know the colour code, pin out details ?

The Haynes manual for the car is no help here either.

TIA

John

Well, here's the link to some Audi diagrams: https://www.the12volt.com/installbay/vehicles.asp?strMake=Audi&page_no=2&sort=

Here's the one I think you might want from that page: 1989 Audi 80/90 Series Stereo Information

Hope that helps.
