Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
Leave the gray flexible cables, the wire harnesses, and the ribbon cables
connected where possible. Any that are removed should be labeled for
reconnection later.
When removing a cable, also remove the plastic cable clamp, if present. It
is normal for some of the cable clamp’s adhesive to remain.
