I have the case, your problem:
The 3 on left and three on right each go to one connector (so two connectors for all 6)
Both of these plug into a Y-Cable splitter that swtiches into a molex connector, which you pluf into PSU.
Obveously the side that has the 3 lights out has the connector undone (they actually come out quite easily), so just open it up and towards the front bottom you will see blu/white wires leading to a two-pined connector.
