Looks like a dension kit in the glovebox.

For the tow bar, you're missing the polysterene basket thingy that goes around the screw for the spare wheel, which holds the towbar itself plus some other bits (have you got the key for it?)

Bit of a crap tracker installation as that cable is very obviously aftermarket.

The door sensors are probably failed, though you may be lucky.
