Not sure if this is linked in another thread about this topic or not, but this is the first thread that came up when I searched for this in Google, so I am adding it here. This guy did a great writeup on this......

I was not entirely sure how the connector came apart, but his pictures helped me know where to pull it apart. The one thing I would add is that you can use a little jewelers screw driver to lift up just a little where the little tab locks onto the hole where the connector comes apart. Otherwise it is really hard to pull apart. You will see the hole on the flat side of the connector and you will see the tiny little tab sticking in there.
