I have no idea, what these are for.... Anyone?

 

Heated windshield

 

These seem to be 2 different connectors, they don't look like they could plug into one another I don't think, and neither one of them is connected to anything... Not to mention, that on driver's side there are also connectors, as well.

 

The purple/white and black wire attached to the firewall is for your heated windshield. There's a matching connector on the other side. Two cables (one on each corner of the windshield) are attached to the windshield and plug into them, but it looks like the wrong connector is installed on yours. The windshield was replaced at some point and somehow (?) came with incorrect connectors? If you wanted a heater windshield, you could find pigtails from a junkyard disco or eBay and splice them on.
