I need to know the sequence on how to connect my Power LED, Reset Switch, HDD LED, and M/B Switch up correctly. I have an MS-7142 VER:1 Can you help me?

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.
Need more information?
Post here.
Good luck carlmtclem!
Thank you for using fixya.
