Thank you tkamyia,makes me feel better on the wiring.
While I checked around I noticed a fuse of ATP type, there were some tags on it, and they refered to aug.1993. This fuse was just to the fender apron of the diagnostic link. If this would be part of the wiring harness, I guess, I can assume that the whole harness was not changed.
But nevertheless, still cant get the code.....
