Can you be more specific? Not all motherboards have the connectors in the same position.
Hopefully, the connector on the end of the cable is unique-enough in shape that there is only one possible "matching" location for it to connect. Look very closely at the labeling on the motherboard, for some text such as "BT", or the unique icon for BlueTooth devices -- a stylized "B" icon.
Also, it is possible that the cable has a "memory" -- from being in the same position for a long time, it retains its curves after it is disconnected from the motherboard. Its "relaxed" position might give a hint as to roughly where it should be reconnected.
