Cable Connector Ends
When connecting chassis connectors to the motherboard, make sure to
connect the correct connector end. Most connector wires are color-coded.
Match the color of the wires leaving the switch or LED to the same pin on the
connector end. There may be more than one connector with the same color-
coded wires. If so, follow the wire to the switch or LED. Pin 1 is indicated for
all motherboard components by a white line. Pin 1 is always nearest to the
white line.
