If you know the coordinates, width and height of each square, you can use the X and Y coordinates to get the top left corner of each square.
Now that you have the left corner, you add an "offset" to it, which would be half the height and width of the square to get the middle.
Then you can draw a line like this
% frame is something like you get from imread or getsnapshot
frame = insertShape(frame, 'Line', ...
[x1 y1 x2 y2], 'Color', "blue", "LineWidth", 4);
% X1 & y1 is the first square
% x2 & y2 is the second one
% by doing so you can connect them

You have an image, therefore you have coordinates. An image is nothing more than a list of intensity values layed out in a grid. You need to determine the location of the red pixels. Do you have any idea where to start with that?
