Install 5" Display
Disconnect the display from the extension socket - we need to install it to the top enclosure part.
Insert the 5" TFT display into the top enclosure part at an angle and slide it in through the clips on the edge of the opening for the screen.
Carefully bend the enclosure back to allow the clips to open and hold the edges of the screen down into place. Try not to press the screen down to the clips as too much force will snap off the clips or damange the screen.
Install flat HDMI cable
The HDMI cable needs to arranged with the wire folded in order to properly close the enclosure.
Bend the wire at the end of the connector and arrange the excess so that it can be tucked into the battery opening near the back of the enclosure.
Install Buttons & Elastomers
Place the plastic buttons into the openings on the top enclosure part. The elastomer set for the action buttons can be held in place by inserting the corner hoop into the nub on the enclosure. The start/select elastomer has a hole in the center that can plug into the nub on the enclosure.
Install L+R Shoulder PCBs
Insert the L and R shoulder elastomer pieces into the holders with the tip facing the openings in the enclosure.
There are six screws that will hold the two enclosure parts secured together. Locate the posts that will join the enclosure parts and fasten #4-40 3/8 flat Phillips machine screws into the posts - this makes it easier to fasten the parts while holding them shut.
Start with the top corner and work your away all around the enclosure. The top of the enclosure has two stand-offs that can be secured using a machine screw and nut.
Secure enclosure shut
The HDMI cable will make it difficult to close the enclosure due to the excess wire. Press the two parts together with one hand and start fastening the screws on the bottom of the part to secure the enclosure shut.
