Connectors with no connections

[dan360]

While investigating another problem, i found 3 or 4 connectors under the dash

(drivers side) in my 84 GL wagon that have nothing to plug into. I don't have power windows etc, were all the harnesses the same for this model?

It appears that another "black box" may be missing under there. I noticed what looked like part of a housing that used to be there just inboard of the fuel pump control unit.
