Automatic wiring shifting facilities are provided to reduce working time by housing wire boxes for wiring of a vehicle automatically, shifting the wire boxes to a working line automatically, and drawing wirings from the wiring boxes and returning the wirings to the wire boxes automatically. Automatic wiring shifting facilities comprises an automatic ware-house unit(1), first and second supply facilities(10,20), wiring supply facilities(30), three sensors. The automatic ware-house unit includes wiring drawing and returning lines(2,3), upper and lower lifts(2a,3a), and a automatic ware-house rack(4). The lifts are mounted on the lines to lift and lower wire boxes. The automatic ware-house rack piles the wire boxes inside the ware-house, and draws an automatically selected wire box to a working line in need. The first and second supply facilities include first and second supply lines(11,21), first and second return lines(12,22), and upper and lower lifts(11a,12a,21a,22a). The first and second supply lines convey the wire boxes having wirings selected from the ware-house rack. The first and second return lines sends back empty wire boxes to the rack. The upper and lower lifts lift and lower the wire box in route change of supply and return lines. The wiring supply facilities includes a wiring moving line(31), a drawing robot(33), and a wiring return line(32). The wiring moving line receives the wire box from the first and second supply lines to convey. The drawing robot has a clamping device installed to the end of a robot arm to pick up wirings from the wire box. The wiring return line sends back the wire box in which wirings are picked out. The sensors senses the position of a vehicle body on a vehicle body convey line. A vehicle body entrance lift(41) shifts the vehicle body onto the working line.
