Orient the motherboard in your mind, so that we are both looking at it in the same direction.
With the computer case open the motherboard will be sitting in this direction;
Processor to the top, (Processor fan on top of Processor), Ram Memory to the right, and the white PCI slots (3) are to the bottom.
The Front Panel header is located at the bottom Right corner. It is situated on the Right side.
(The plastic front of your computer is the Front Panel. The area of pins on the motherboard that the Front Panel cable, (Wires), connect to is the Front Panel Header)
There is two columns of pins. The header itself is vertical, (Parallel to the Right side), with pins arranged in two's going down the header.
In the Motherboard Manual (Product Guide) on Page 12, the letter S points to the Front Panel header.
The Front Panel header's pins are numbered. The numbering begins from the BOTTOM of the motherboard, and increases going towards the top.
(Page 35. The letter E points at the Front Panel header.
It is also named J9H3. Junction 9 Header 3)
Bottom RIGHT column starting from the BOTTOM of the motherboard, going towards the top,
Pins 1, 3, 5, 7, and 9.
Bottom LEFT column starting from the BOTTOM of the motherboard, going towards the top,
Pins 2, 4, 6, and 8. (There is NO Pin 10)
1) Pins 1 and 3 are for the HarDDrive Activity LED light. (Blinks when the harddrive is active, and in use)
2) Pins 5 , 7, and 9 are for a Reset switch. (Reset button)
This is IF a reset switch is used.
(This is what CTRL, ALT and DELete are for)

If the HDD Activity LED light, or the Power On LED light are dim, switch the wires around]
