Front Header Pin Polarity

[angelars]

Using a Cooler Master Elite 130 case. The instructions don't tell you the polarity of the front header pins for the power switch, reset, LED, etc. On the pins there is a arrow on one side of the plug. Does anyone know if this arrow is positive or negative?

Power and Reset are not polarity dependent, connect them either way. The LED is seperated into 2 pins, usually with a space in between each pin, On the board, looking closely enough you should see the pinout written on the PCB below the front panel header on the motherboard.
It will be LED + or LED -
