Depending which way you’ve installed the screen — horizontal or vertical —one “T-slot” will be located at either the left or the right side.
For a VERTICAL SCREEN: the T-slot should be on the LEFT. If it’s on the right, you’ve got the screen piece upside-down.
For a HORIZONTAL SCREEN: the T-slot should be on the RIGHT. If it’s on the left, the screen piece is upside-down.
Only one of the two speaker/screw holes is used, depending which way the screen is oriented.
If your wire bundle has only four wires, you can skip over the Sel pin; it’s not being used here.
First, feed the quick-connect wires through the corresponding slots on the joystick plate.
Loosely fit the button support over the joystick support. It’s okay if this flops around for the time being…everything will be held in place later.
Be super extra careful to get the headers correctly aligned. There’s enough wiggle room either direction for it to go one pin out of alignment!
