Hi IvanMuse007
consult your manual or download manual pdf from your motherboard manufacturers website and look at how to connect your front panel connectors
if they are not labled + or - , generally + is the red wire - the black wire

But i have white and purple on power sw., +p led orange, -p led green, hdd led red and white and blue and white on reset sw.
In manual it says + and -, but hdd led has two wires so it can be connected in two different ways

It really isn't that hard just look for little black arrows at the end of the cable that looks like this http://cdn.overclock.net/f/fb/350x700px-LL-fb7efa3a_diy39.jpeg some people just describe it to be harder than it actually is

The arrow is always positive

Look for a black arrow on the back of it. Look at the picture that I posted, where the black arrow is on the connector is always the positive

Download your manual here
http://au.msi.com/support/mb/H67MSE23_B3.html#down-manual
go to page 2-14 there you will find your front panel connector
your cables are labled , with the hdd led the red wire is +
the rest will be marked on your mobo beside the connector , if not refer to the manual

Ooh didt know that arrow trick good to know

They won't be in the front where the white labels are, they are bumped up on the back of the connector. Take a flashlight and look at the back of the connector

The common color is negative (usually white, sometimes yellow).

 

[IvanMuse007]

I know that arrows are on the back so everything should be positive
Sorry but i dont know much about this

 

[IvanMuse007]
