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. All motherboard
components are outlined by a white rectangular box with a broad arrow at one
end. Pin 1 is always at the arrow end of the white outlined box.
