Loose cables in the boot

Hi everybody
I am new to the forum and to the RR so I apologize for this if there is the same question or theme!
I have loose cable in my boot and I realy do not know what are they for. If you can help me I would very much appreciate it. I will ad pics.
And also I am trying to do the "WiFi" fuel burning heater, but can not find the 3 cable socet.
Thanks again
