Dimension of Component
X dimension (normally left to right): -

The centre of the connector to a hole on the far left is 10.2 mm (bottom picture). That hole to the hole a bit right of it is 1.4 mm (middle picture) hence, the centre of the connector to the hole dimension you want is 8.8 mm.

And this ties in with the dimension of 17.6mm (gap between the two symmetrical holes) i.e. 8.8 mm x 2 = 17.6 mm.

Y dimension (normally vertical): -

The middle picture shows 0.7 mm vertical to the little hole on the left and the top picture shows 2 mm vertical between that little hole and the two symmetrical holes. Hence the vertical dimension is 1.3 mm.
