I work for a small engineering firm and have always built our computers from the best parts available, including Intel Motherboards. One thing I have never known is this: The front panel connecting wires are color coded and usually have a black or white wire also. Which wires are the PLUS and which wires are the MINUS? The + and - are clearly marked in the manuals but no one is saying whether the color wires are + or - . Usually I just hook them up and if they don't work I switch them. I am very tired of this and I am desperate for the answer to this question. Help!
