Name those engine connectors

So I bought a none running 91. Got the truck to fire now but can't figure out where these 2 connectors go.

The big flat one looks like the MAF connector, and I "think" the small one is the o2. which would mean the ECU is in "Limp" Mode

I was thinking maf also, but the maf sensor is attached to the left side of the engine bay correct? I tested the one i'm referring to, and it does connect to the maf. I will check when i get home to see if the o2 sensor is connected. Both of these pugs are within the same loom of wires that lead to water temp sensor and whatever else is over there.
