Installation is about as simple as it gets. There are 3 wires, two of which come together to make the third. This third wire hooks into the EasyUSB and goes in only one way (thanks to a guide pin; actually lack of a pin for that matter). The other two wires go into the extra USB header on your motherboard. This is where Antec's model differs from the FrontX port: it actually uses the other header on your mobo instead of wiring all the way to the back of the case. Anyway, on each of the two sets of wires there is a red one with a sticker marked "power". This one goes into .. you guessed it .. the power pins of the motherboard header.
