Those wires just don't want to stay in their black connector housing! I went to look at the wire order on the MBP I just disassembled--and two of the wires came out of that one as well! So I just looked at the logic board of my other perfectly-working MBP, since I also need to know now. The order is: gray - thicker matte black - thinner shiny black (when viewed with connector attached to the board and all of the ports are to the left of the connector). I'm putting a small tab of black tape on the wires and connector to hold them all in place until they get reinstalled and taped to the logic board. Good luck!
