It turns out that I just bought a megane coupe i of second hand and brings the cables of the cut radio.
I do not know what is which since they are not as in the ISO connectors, I have:
2 white
3 green
1 orange
2 brown
1 yellow violet
nose ... many rare colors ...
If someone has the scheme of how they go or if they know the colors would be of great help.
Here are some photos to see what I speak.
