Need Help 1990 RS 3.1L Emissions

I’m posting this in hopes that someone can answer a question I have and I’m having some difficulty in finding an answer for. I recently purchase a 1990 3.1L MPFI RS Camaro for my little gear head of a daughter that was someone’s project car. After we got it back together we realized that some of the stock emissions equipment or the AIR pump (smog pump) is missing. When facing the engine or the pulley side of the AIR pump. I see two fittings at the back of the AIR pump. The right one has some sort of switching valve then a check valve then terminates at the right (passenger side) exhaust manifold. The fitting on the left of the AIR pump is just open.

My question is, does anyone know what I’m missing (parts, tubing etc.) how this should be routed from the AIR pump to (air intake, catalytic converter, etc.) and were I might find the parts, valves tubing etc. for this?

Any information would be greatly appreciated.

Thanks
