USB Motherboard Cable Assembly Information

Although, the following was written using a Belkin brand motherboard cable assembly, the information generally applies to all USB motherboard cable assemblies.  I personally use and recommend the Belkin Pro Series Motherboard Cable Assembly Model #F3U001.

USBMan WARNING!  Read This First!

Improperly wiring a USB port can result in permanent and fatal damage to the motherboard, the USB port and ANY peripheral connected to the motherboard.

It is imperative that the specific USB pin out assignment for your motherboard make and model is obtained from the maker before any attempt is made to connect the cable to the motherboard.  Simply knowing which pin is #1 is not enough information to properly wire a USB port.  Trial and error will surely result in the destruction of the USB host controller, the computer system and/or any attached peripheral.  YOU MUST obtain the exact USB pin out assignment from either the motherboard manual or the manufacturers web site.

Adjust the Harness to Match

The wires of the cable assembly can be easily moved to match the pin out assignment.  

Press on the side of the wiring harness at the indentation next to the wire that you want to move.  This will release the wire from the harness.  A straightened paper clip, straight pin or precision screw driver works well for this purpose.  When you have positioned the wires correctly, secure them in the harness by depressing the harness tab again.  Take care to lift the tab only enough to release the wire.  If you lift the tab too high the plastic tab will not reset and the wire connection will not be secure.
