Air Cleaner hose clips and connections?

[kna4977]

Original air cleaner has a hose connector on top on the diaphragm at the front of the air cleaner which the stove pipe that comes up from the driver exhaust manifold connects to. Under the air cleaner are two ports and a hose holder. Nothing connected, but what is supposed to be here and where does it route and connect? Here are some pics. What hoses should be in place, how should they rout, where should they connect.
