Cigarette lighter not working.

[Justachick]

Hi all
My cigarette lighter isn't working, and hasn't done since I purchased the car (second hand) some time ago. I assumed, like most people, that it would just be the fuse, however after finally getting around to replacing the fuse, its still not working. So being the handyman (woman) that I am, I pulled out the console and had a look around. First thing i noticed is that there is an extra cable and plug, and be effed if i know what its for or where it came from. Everything else seems to be in order. I have added a couple of pics that hopefully will give you an idea of what I'm talking about.
Any help would be much appreciated.
