Question Need help identifying these connectors!

Ok, I'm doing the standard Replace-The-Crumbly-Wiring-Harness job on my 1994 e320 wagon. Since I acquired the new harness used online, (says Delphi Werk Bochum, MB 124 440 5632 on it) I figured best to lay it all out and make sure I can verify I know where everything goes before I start anything.

It all seems fine until I reach the very last 4 little barrel connectors (2 pairs). I figure one pair probably goes to the leads from the air pump, since those leads are wrapped around a hose on said pump instead of being connected to anything (the issue with the car is idle emissions and sometime erratic idle). But I have no idea WHICH pair would go to that or what the others would plug into; it appears the harness currently installed was cut. See attached pics. Any ideas? Please?

Can somebody maybe take a good picture or three of that spot on the front of the engine where this thing terminates so I can see what those wires are plugged into? Need to get this car back into action real soon now so I can go to the beach Thursday night... (must leave at least one running car here, and alas this family has only 2 cars!)

Gently pull back the block covering and identify the colors of each wire and which they are paired with. Include the secondary colors if any. That will go a log way in figuring out that they are for.
