Hi all
I am doing an interior upgrade for my 1990 S2, The new interior I have has the M490 10 speaker upgrade. Unfortunately I was not able to get the speaker wiring harness with the interior so my questions are :-
1, Does anybody have a link to a wiring diagram for the M490 system ?
2, Can anybody tell me which wires to connect to the connector block on the cross over ? I am assuming that the tweeter and the head unit connect to it, I just don't know which one will connect to which wires.
I have a pair of green/black and a pair of brown/blue

Thanks in advance
