I have got a tower which has a black wire and red fire at the front panel connector to the motherboard's front panel connector? So I was wondering which is the negative and positive one, for the power switch? I think that the red one is the positive and then black wire is the negative one, which is similar on a car battery charges? I have also found another front panel connectors as well and those each have 2 wires, like for example the reset switch, and they are blue and white, so again which one is positive and which is negative? The hard drive led also has one orange wire and other is white wire, which is positive and which negative? Then there is a micro sw., which has one black wire and one white wire, so which is positive and which negative? So can anyone tell me about this things?
