EZ Cool Alpine + Gigabyte GA-8I915PM mobo

[Squiggley_Jo]

I have an EZCool Alpine case, i aquired the the system from a friend and need to replace the asus mobo. Im replacing it with the Gigabyte GA-8I915PM mobo, but i need to know which lead is which (from the front panel) and where on the mobo to connect them to as i have not got that far in my course. any help would be much appreciated as i have searched high and low for the case manual and the mobo manual :D

wires include:

VP, VG, TPA+, TPA-, SHEILD (i have no idea what these are for)

L-RET, L-OUT, R-RET, R-OUT, MIC POWER, MIC OUT, GROUND (im guessing this is the headphones and mic)

1-D, 1+D, 1 VCC, GROUND (i have no idea what these are for)

2-D, 2+D, 2 VCC, GROUND (i have no idea what these are for)

Thank you in advance
