Are they gray?
EDIT - ok, see the photos now.
The lower (middle) one looks like the coding plug that should be attached to the side of bracket that holds the LH / EZK.
No clue on the other one, need a different angle.
Here is where the coding plug goes:

car doesn't have a fuse box. It does have a central electric panel, where the fuses are located, along with the relays and the harness plug connectors. As others have said, post pics of the stray wires. could be an unhooked O2 sensor. Could be an old after market alarm or stereo.

The factory looking one on the far right is for the O2 pot.
The other two do not look factory. Take the bottom board out and trace them to their origin. They will lead somewhere...namely to the answer to your question.

I'm stumped. Not sure what those large connectors would be for. They are very beefy. Do you have an after market amp somewhere in there, or an after market screen in the consol?

One is the coding plug. The other is the seldom-used and mostly-doesn't work diagnostic port (replaced in '89 with the 19-pin plug in the passenger "hump".) Both are usually fitted to the ECU bracket.
Other than not being fitted to the slots in the bracket there's nothing obviously wrong that I can see.
Oh. The three pin plug is for the CO pot for non-cat cars.
Still nothing wrong as long as he coding plug is plugged into the harness and it looks to be.
