Go to nemiga.com and look up the portions of the electrical harness that install in the front of the car. Should also give you an idea to what the connector is for.
Use WIS schematics and the wire color codes on the real world connectors to determine to what they should attach. I would help out but I just got my car back together and I don't intend to take it apart again for awhile...
Connector in first photo looks like a low-power circuit (small connectors, small diameter wire). e.g sensor of some kind
Connectors in second photo look like higher-power circuits (larger connectors, large diameter wire). e.g. motor driven circuit or heating element.

Looks like ac kompressor for the smaller one. The bigger one is front center bottom next to where the radiator fan plugs in(bottom of ac condenser)?
