Lift the blue hard drive mounting bracket out of the iPod.
Carefully disconnect the white battery connector from the logic board. Be sure to pull only on the connector itself and not on the cables.
Like the hard drive connector, for the following step, you only need to move the connector about 2 mm. Pushing too hard or too far will damage the connector.
Loosen the touch wheel connector by pulling the brown locking bar toward the side of the iPod using the tips of your fingers.
