"vcc usb2-, usb2+, gnd, vcc usb1- usb1+" - all those will be labeled in the mobo manual. I had quite a time hooking all mine up (lights and front USB), but eventually you'll get it. It's just a matter of counting pins in the block of pins and being able to follow the + and - in the manual. If no manual, look on the internet- there will be a diagram somewhere.
