Help with connecting speakers up to mobo properly!?

[Unisol112]

Ok, So I have an MSI Z97 Gaming 7 MOBO and on the I/O it has Line-in, Line-Out, Mic, RS-Out, CS-Out, and SS-Out audio jacks. My speakers that I have bought are Logitech Z506 5.1 surround speakers and they only came with a green aux-cable and a black and peach colored cable that plug into jacks on the back of the subwoofer labeled R and L. I can't seem to figure out how to plug these in the right way to make the speakers work like they're supposed to. For the time being im just using the Aux cable plugged into the headphone jack on my pc. I'd really like to connect these the right way.....Any suggestions!? Please help!

That helps as far as making the subwoofer kick in but I still get nothing out of my center speaker. Thank you for the help M8.

Center Speaker will work if you plug the Logitech Z506 cables as under:

Orange - C/Sub
Black - Rear and
Green - Line out.

Cheers.
