Nice display. So tiny :) No labels on wires at all, but I found some help online: Red: + Black: - Yellow: n/a Green or blue: connected momentarily to ground changes the brightness up or down. White: Video ground Orange: Video signal Worked ok with 5V. Must be kept really close to eye in order to see the whole screen.
Great product, easy to use (red is +5V, black is GND and the last 2 wires are composite)
