Step 4

Use the point of a spudger to push on alternating sides of the fan connector to "walk" it out of its socket.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.
Don't push or pull on the cables themselves, or you may damage the connector.
