What are these wires?

Good evening,
I'm trying to identify a few loose wires... do you recognise any of these?

The last one should be of the rear fog lamp. I do not remember my fuel tank wire running so loose under the car...

Thanks Andrea, I suspected it was that. That photo was taken a long time ago and the fuel tank wire is all safe now.

The other ones are the real mystery. Do they even belong there? Sometimes I can't tell what was installed by Renault and what was installed by previous owners.

Out of memory...
I definitely have cable #1 & cable #2 - both unused as well.

I've got the connection in your second photo hanging in mid air, but it's closer towards the headlight.

I'm so glad that I checked because I discovered that one of the wires to the starter motor was actually touching the manifold and the insulation tape was brittle and burnt.
