So . . . the hopper says it picks up items when energized. The lever says it energizes. Attaching a lever to a hopper, and flipping it, doesn't make the hopper work. Connecting the hopper and lever with wire doesn't work because levers can't be placed on wires. (Placing a lever adjacent to the end of the wire, and flipping it, also doesn't do anything.)
What am I missing here?
