Hello Randy, the terminals are located near the SATA ports. read your motherboard labels near it and you'll find the connectors, its very basic, you can figure it out. plus signs are green for the power led and orange for the HDD. read the wire connector of your PC casing.

I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

Cut and paste this link...select the DOWNLOAD tab, click on MANUAL.
Choose the 2.0 version of the manual. It supports 2.X versions of the motherboard. Page 2-14 has the infomration you need.

At the bottom right hand corner of the mobo you'll find there is a set of pins marked JFP 1 and the power switch pins are marked clearly so are the HDD Led, reset, Power Led etc. Plug in your wires which are also marked, corresponding to the marked pins.

Link to your manual, drivers and BIOS :

Hi carlmtclem, your not alone when it comes to hooking up the right led connector to the MSI MB. Firstly, you need to know what wire color is positive & which is negative. Most commonly the color white is ground/negative. Wire colors do vary from case to case. So look at your case led wires. Which ever color is common for each 2-pin connector, is negative. (Except the speaker wire).
All other colors are positive.
(The speaker wire color for negative is usually black & red is positive).
Your MSI board has two separate sets of pins.
JFP2 is used for the speaker only. Do not connect the power led there.


Pin one for JFP1 is shown in the manual. Pin 1 is positive & pin 3 is negitive for the HDD-LED, ECT.


Thats it.

Good luck carlmtclem!
Thank you for using fixya.
