May be the ground pin you are looking for is the pin No 10 black square in the figure (right bottom on the connector view shown)

This is a 2 rows (2x5) connector. Just all the unused pins were grounded.You need not to use them. Use only the one in black if you want.

As rightly pointed out by pauloynski, you can use one ground. If you see the connector, may be all grounds are not wired. Use the one that is wired and the balck one is.
