1st-build confusion: Antec LED wiring doesn't match Asus Mobo. Help!

[dstrain]

I'm stumbling through my very first build and after a good 4 hours I'm stuck on trying to match the LED wiring from Antec Lifestyle Sonata II case to the correct spots on the ASUS A8N5X mobo.

The colors don't match up exactly and the orientation is different. Antec says make sure labeled sides of the wiring face towards the front of the case - which means they'd be facing horizontally and in a row, one behind the other. However, the Asus instruction have the wiring-plugs facing vertically, and grouped parallel to each other. I also don't have any clue which wires are ground wires, which ones are positive, and which are negative on the Antec.

Is there a standard color or symbol or anything to determine ground, + & - when color schemes don't match?

Red wire is +, black is ground. The positive pin should be labelled on the motherboard, so connect the wires using that.

You won't hurt anything if you put a LED connector on backwards - the power LED just won't light up, and the HDD LED will simply always be on. If either happens, just reverse it, no harm done. The power and reset button leads are not polarity sensitive. However, front panel USB and Firewire connectors *are* critical - you can cause damage here.
