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.

I need to know the - 4214cb1.jpg
Pin one for JFP1 is shown in the manual. Pin 1 is positive & pin 3 is negitive for the HDD-LED, ECT.
