Help with connecting case panel cables to MB

Im building a system with a Fractal Design R3 case and a Asus x79PRO MB.
Im not exactly a newbie, but it has been 10 years since I built a system.

I need help with sorting the cables from the front panel.
The case connectors for the power switch and reset buttons are not marked for polarity but the MB pin are marked for +/-. .
From what I remember from the old days, it the reset button has no polarity, but Im not sure about the pwr button.

Even more confusing, the pwr LED connector has both connectors marked at positive (+), am I missing something?

all three connectors (PWR, RST, LED) have wires that are color Red and White, can I assume that the red is +?

Thanks in advance,

A
P.S. the case has no MB speaker nor a HDD LED light.. hummm..

Red is positive, white is negative.

What would happen if I'm wrong and I connect in the wrong polarity?

Nothing other than your LEDs wouldn't light up.

I finally got an answer from the case manufacturer, apologizing for the wiring, saying that the color of the leads signify polarity (red =+)...

Yep, that is what I said way back at the beginning of your thread. Glad you got an "official answer". Have fun!
