How do I use a logic level converter?

I don't see any schematic. I see 2 blurry humongous pictures of boards & wires with no indication of what is connected to what, or what is what even.
Can you draw a few blocks on a piece of paper and clearly show what pins are connected to what pins? And scale it down to no more than 1000 pixels wide before you post it. You must have written something down so you could tell everything was connected when you were done, yes?
