The pin out of the touch panel on the CFAG320240CX-TFH-T-TS is

1 - Right (X-)
2 - Left (X+)
3 - Bottom (Y-)
4 - Top (Y+)

Pin 1 is the bottom line on the FFC of the touch panel when you have the module in front of you with the touch panel FFC to the LEFT of the display (see pin out / drawing on page 8 of the datasheet)
