Locate the orange cable to the right of the battery tray.

To detach it from the connector, use a tweezer to gently rotate the black piece on the connector 90 degrees so it is pointing up.

There may be a yellow mylar sticker on top of the white connector. Peel off the sticker and continue.

Once the black piece is pointing up the orange wires can be removed from the connectors. Using a tweezer pull the orange wire horizontally outwards from the white connector.
