The connectors you are showing are electrical connection to the Trunk.
#2 is the Fog light connection. If left in the condition as shown it may get crushed by the spring. I have replaced several connectors for people because of this problem. Had it happen to me
#3 Cable shown is the Air Pressure and Temperature Sensor (taped cable) and Fog Light.
There is an extra connector on each side in the picture which I added for my added lighting. All the cables and connectors you show should be pushed up and forward into the cavity at the top backside of the Trunk. It is a pian.
