I haven't gotten around to tracing it, but behind a rusted-out cover panel in the passenger side rear wheel well, it looks like at least two cables or hoses or something running up toward the fuel filler door area.
Part of the central locking system (I thought I heard something about it locking the fuel filler door too?)....part of the fuel system (though can't think of what it would be)?
