I am attempting to salvage an iMac G5 20" Model A1076. Upon reassembly the black cable with six wires that connects the Inverter to the logic board  disconnected from plastic six prong female plug where cable plugs into logic board. Is there a schematic that provides the proper pin-out for the six wires that attach to the logic board?

eli Lucas, you will have to post an image of your inverter and the cables with your question. The wiring on your connector from left to right is: 24V 24V Ground Ground Brightness 3.3V an image of where the cables are connected on the inverter should help to figure out which wire is what.
