Clock has the 2 gray wires with bulbs, as they are 12 v live, since no circuit board on clock to feed them (just grounded on clock casing). The wire on left is simply put in an empty socket with circuit board behind guages, and yes it is a fiber optics which goes to ashtray. Other one I can't remember if it's anything special, as it seems to also have bracket to attach fiber optics cable.
