Can anyone identify these?
First, a box behind the storage pouch on the passenger's side:

When I removed the lid, this is what's inside:

Second... I found this hose stopped up with a spark plug:

Last Photo is a part of AIR injection system. The air diverter valve should be connected to the AIR pump (aka SMOG pump). Smog pump should be on low passenger side.

Thank you for the reply, RFMaster. That would explain why I didn't recognize it. This car was built in California, and I live in Florida. I've never seen a smog emissions *anything* in a car before. Sad, isn't it? So, given that this is plugged, I'm willing to say that this car is *not* green.

Its cruise
The diverter valve splits the air injection into left/right banks (the tube things) and one to the cat. The one to the cat appears to be plugged, likely from exhaust work

So... does this car have a catalytic carburetor then? The only reason I ask is because I was told that a catalytic converter was only used with fuel injector systems. I'm not a mechanic, and this is my first project car, so I'm learning as I go.

Just look under your car - if there is a big can looking thing sitting straddling exhaust pipe next to transmission than you (most likely) have a catalytic converter. For sake of completeness - all new cars sold in USA starting 1975 model year were mandated to have catalytic converters. Carb or FI does not matter - all third gens sold in USA came equipped with CATS.
