1) You don't have to disconnect the keyboard cable to replace the WiFi card.

2) You may have three wires connected to the wifi card, disconnect all three

3) If your new wifi card has three sockets the grey lead heading off towards the front of the machine is for the middle socket; it has a plastic wrapper that can be slid off.
