I searched a few of these threads and didnt find what i needed so i figured to post and ask my own.

In 2007 i bought a case never built it. Here it is 8 years later i bought parts for the case. Its an AeroCool AERO-X202, not much info left on this anywhere. I know where 5 of my 8 pins go for this, im just not 100% sure where the other 3 go. These are single pin plugs. This is what i know and what i think i know of the other 3.

Mic - pin 1
Ground - pin 2
Mic Power - pin 3
R Out - pin 5
L Out - pin 9



Ground(2) - pin 4
R Ret - pin 6
L Ret - pin 10

As far as i know this is right. My motherboard manual shows the top 5 pins, but that is all, says refer to case manual(which there never was one)for single pin configs. There is a difference in the 2 ground pins also, one is thicker than the other, im assuming that would be pin 2.

Can anyone shed some light on this for me?
