What might help you is to first start with drawing a proper schematic instead of the wiring diagram you posted. You can, for instance, use https://easyeda.com/editor (https://easyeda.com/editor) to draw it.
Use the correct symbol for the different components. Like for the LM339 which houses four comparators use the triangle symbol shown in the datasheet. https://www.ti.com/lit/ds/symlink/lm339-n.pdf (https://www.ti.com/lit/ds/symlink/lm339-n.pdf)
If you still don't understand how it works after doing that come back here and post the schematic in this thread.
