Compatibility question Nokia active system

Hello V8 lovers,
now I have a big ship and have a lot to get him back into the clean.
In this case, I'm talking about the radio.
I've found out that I'm probably back Nokia Active
Boxing in it. At the moment, only 5 cables hang around, the tweeters are still there and a normal speaker has been installed.
I would now like to know the PIN occupancy of the single cables back there to be able to connect the LAutsprecher correctly at least once.
The next question would be: In the bay there are some hits to Nokia boxes, but often in connection with Audi 80. To what extent has all this remained the same? I can get those speakers. In connection with the correct adapter on the radio which then takes the red plug with it, should all work well, right?
Hope you can help me in this case.
Also have a Bose system in the eye, radio, front boxes (or box boxes) wire harness and rear speakers + door boards. Make sense?

greetings
Christian
