Logitech Z623 sound system

[Rosta99]

Hi,

I am using sound system z623 (2.1)

Right speaker is connected straight to subwoofer with 15 pin d-sub kabel.

There are 2 thicker veins (red, green) and 13 thinner veins (white, gray, yellow, violet, orange, green, green/white, red, red/white, black, black/white, blue, blue/white)

I would like to know which color is connected to each pin (1 - 15).

I think 1 - thicker red and 6 - thicker green, but not sure about other ones.

Thanks for the answer.
