connecting power switch, led's and front USB headers to mobo

[The Dancing Peacock]

So I have the motherboard in the tray, I have the chip in, the heatsink installed, got the cliip down no problem. Now I'm looking at the motherboard book, and it shows me where to attach the power cables for the fron LEDs, the power and reset buttons, and the front USB ports. What it doesn't show me is which side is the positive side, and which is the negative. It just says, attach HD LED to header pins 1 and 3. I'm trying to err on the side of caution, so I don't want to plug it in any which way. Am I dumb, and not seeing something painfully obvious, that you all are gonna laugh at me for? Or is the book not telling me everything I need to know?

About the USB ports, theres a USB1 header on the motherboard. The motherboard book calls it the extended USB module, and only points out pin 1. Will this support the front 2 usb ports, there are 9 total pins, but there are are only 4 each from the 2 front ports. Each port has 4 seperate wires :

Ground
-D
+D
+5V

Any help would be appreciated. I have an ECS K75SA and an XP1600+.

I am not familiar with that board but as far as the LED's you wont hurt anything if plugged in backwards they just wont light, if this happens just turn it around. Dont know about the usb ports.

what about the power and reset buttons?

it shouldnt hurt if u have them in backwards. just make sure you have the labels facing one direction. if it dont work, reverse them all.

as for the usb, dunno. im having a slight prob too.

on my old Asus CUBX, it was fool proof because there was one pin on the connector that was blocked out. it fit like a perfect puzzle onto the board. now the MSI i have now is a bit tricky.

power and reset buttons don't matter if they're reversed, they'll still work correctly. the LED connectors, if they're reversed you'll get the exact opposite (in almost every case) than what you'd normally get if they were connected the right way, so you'll know.

The darn power LED takes up 3 pins, Green wire, empty hole, then the white wire. The mobo only allots 2 header pins for the power LED. I guess I need to sniip it and attach a new one.

Are the white wires the negative ones?

 

[tornadobox]

if you look at the plastic piece of the connector, there should be a little triangle (this denotes either positive or negative...heheh i don't remember which!)

in any case, for the power led you can either cut the connector in half and shave the extra plastic so that it'll fit, or you can push the wire you want to move in (towards where you'd plug it into the board), lift up the TINY little flap in that wire's socket (plastic piece) and then while that flap is up, you can pull the wire out and plug it into the middle socket so that it'll connect to your motherboard.

hope that all made sense!
