I'm in the process of building my new computer right now, and I don't know which way to connect the the system power led, hdd led, system speaker, reset and power switch connectors to the motherboard. My motherboard and case manuals (p5b-e and lian-li pc7b plus) don't say. Do the negative and/or ground pins connect to the white wires? The speaker cable has one black and one red wire...does the black connect to the +5v pin or to the speaker pin?
