What about the 6 pin connector? Does your control panel have the 4 pin connector plugged in? Can you get a better picture of the end of the connector, showing the locking tab? And a brighter picture of the 4 pin area on the control box?
If you hadn't guessed yet, the 4 pin connector goes to the touch panel. With that disconnected, nothing works. If you bought it that way, be prepared for the system to be badly broken.
