This is MSI/Support and the download page for the MSI MS-7104 V1.0
Motherboard Manual in Zip file form,
Granted, it's not the 2.0 version, but the Front Panel header is the same.

Click on the button with the countries name that is closest to you. I clicked on U.S.
If you don't have your downloads set, to download to your My Documents folder, it will go to your desktop.

Double-click on the file name. You will see the Extraction Wizard come up.

Go up to the top left, and click on Extract All Files.
Now you will see a PDF file on your desktop screen, with the file name under it. Double-click on this PDF file.

After you have opened it, and everything is there, you can go back to the Zip file on your desktop screen, right-click on it, and delete it.
Delete it from your Recycle Bin also, or it will be taking up needless room on your harddrive.

Orient the view of the motherboard, so we are both looking at it the same way.
The processor is at the Top/Middle, and to the very bottom right, is the JFP1 header. (Connector on a motherboard is called a header)
Over to the left of the JFP1 header is the JFP2 header. Looks to be about one inch over from the JFP1 header.

We'll start with the JFP1 header.
The JFP1 header has 4 pins across the Top. Then there is a place for a pin. No pin for where no.5 would be.
The JFP1 header has 5 pins across the Bottom.

The pins across the Top are numbered -> 2, 4, 6, 8, and 10, but there is NO, No.10 pin.

The pins across the Bottom are numbered -> 1, 3, 5, 7, and 9

Pins 2 and 4 are for the Power LED light. It doesn't have which pin is the Positive (+) but I suspect it's Pin 2.

Pins 6 and 8 are for the Power On switch. Doesn't matter which way they go, it's a switch.

Pins 1 and 3 are for the HDD activity light. I suspect Pin 1 is the Positive (+) connection.

Pins 5 and 7 are for the Reset switch. (If you have a Reset button. If not, don't sweat it)

Pin 9 is not used.

JFP2 header:
The JFP2 header has 4 pins across the Top. They are numbered
2, 4, 6, and 8.

There are 3 pins across the Bottom.
They are numbered 1, 3, and 5. There is no No.7 pin.

Pins 2, 4, 6, and 8 are used for an internal speaker. This speaker would be used to hear any BIOS Beep Codes. I suspect No. 2 pin is the positive (+)

Pins 1, 3, and 5 are used for the Power LED. I suspect what they're indicating, is an LED used to show Turbo Boost. In actuality I'm not sure. If your Power LED has a connector with three socket holes, it goes here. If your Power LED has two socket holes, it goes to the JFP1 header, and to Pins 2 and 4.

On most motherboards over the last 10 years, they have printed the pin out positions of the forward led and switch connectors. Sometimes it right next to the pins and at other times it is slightly away on the motherboard in an open area. The only thing you have to watch for is the leds because if you plug them in backwards they do not light. There is usually a little arrow on the wire plig to signify the + cable of the led. The motherboard is also marked with a plus or minus usually also. Good Luck, RAC
