Warning - Noob question

I am trying to follow the instructions provided by the vendor https://learn.adafruit.com/2-8-tft-touch-shield/touchscreen-paint-example to no avail. Specifically:

We connect the 4 pins as follows: Y+ is connected to Analog 1 Y- is connected to Digital 7 X+ is connected to Digital 6 X- is connected to Analog 2

My board looks like this

shield board

and I cannot see any X/Y/+/- labelled pins. I then found the schematic of the board

https://github.com/adafruit/Adafruit_2.8_Inch_TFT_Shield_PCB/blob/master/schem.png

where these pins are labeled but what is the representation of the schematic on the board?

Finally, once I do find the pins, how do I connect them if they are already used? Do I have to use a breadboard?

Edit: After the helpful comments of jsotola, I got a photo:

Are these the 4 "pins"? If so, how on earth do I connect these to the arduino?

  • I thought the touch panel and the LCD are essentially the same thing because they are embedded to each other.

  • I did try the example, the colored boxes showed up fine but no touch input registers.

  • @jsotola do you know if I can detach the TFT from the board to inspect the connection of the touch panel? I inherited this arduino / TFT and I do not know the history of its touchscreen. Yes I am using the tftpaint_shield sketch
