bottom head cover.

The Head-cable Interconnect must be facing up and the fans facing down.
CAUTION:
Be careful not to damage wiring during the next step.

that hold head cable assembly together. Cut the two wire ties that attach the head cable
assembly to the Color/Effect/Strobe module.

(4 cables).

bottom of the module to pass through the openings between the attachment points.
