Good chance they're for accessories your car isn't equipped with. When I took mine apart I took photos of every wire I disconnected as well as every terminal that wasn't connected to anything. Said photos came in very handy when I re-assembled the car. I browsed through the photos and didn't see anything resembling the ones you showed.
Remember where they are, put the car together, start it up. If everything works, good to go!
