The wires that connect to the motherboard jumper for the front pannel how can you tell which is (+) and/or (-)

The wire that should go to positive (+) is usually red, while the one that goes to negative (-) is usually black or blue.

Only the power and HDD LED's have polarity, the others work either way. Red on HDD and Green on power LED are positive.
