The cable here looks like the power cable hookup, so this is a good start. You will need at least three wires from this harness. The red, black, and yellow. If you are only using this as a display and nothing else, you will still need the "Hideaway Unit" to connect up any RCA video. Do you have that piece too? It has a special cable that fits into the large connector on the back of the deck on the left. Without that, I think you may be in trouble.
