[PsYcHe]

Did this with reverse sensors in my D2.. if you peel back the carpet a bit in the corner of the boot, on the back of the seat should be some round (and very sharp!) holes, push the cables through one of those in the bottom corner, and you should be able to get to them from the inside, initially by pushing your hand between the seat cushions, then pull it through and position under carpets, etc.
