Hi! I have got an abarth sat nav unit, and im tying to wire a line output converter to it. I think i have found the the speaker wires but not sure.. I have to connect green, black, grey and brown wires from the line output converter to the same colour speaker wires.. But i cant find a brown speaker wire help!

Below is the connector diagram for the speaker plug on the CN+ according to eLEARN. Unfortunately, they are not always accurate.

M = Brown
MB = Brown/white
H = Grey
S = Pink
V = Green
Z = Purple
CA = Orange/blue
