The four wires on the connector should be all you need to get it working with a composite video source.  The red wire and the black one next to it are for power.  I tested mine using a 9V battery (red is +, black is -).  The yellow wire is the center pin on your composite video cable, and the black wire next to it is the ground of the video cable.

Hope that helps.
