Hi Show,
Looks like our cars are the same color on the inside- mine is still brown on the outside as well!
Here’s a picture of the device- the huge hose still goes to the crankcase breather on the engine, the breather hose by the oil cap goes to one port of the black plastic 4 port piece. The two top ports go to the rain hats, the last port is where the vapor canister hose attaches. This is basically how the CIS airbox was “fed”. The only difference is the airbox had a small drain hose if the oil quantity got to be too much.
I have thought about drilling a hole in the 4 port piece and connecting the old CIS drain hose, but haven’t yet.
