Pre-Production MR-B3RB LIDAR cable drawing

Note that the LIDAR does not come with a cable from the factory. In Pre-production the adapter cable has been hand made. Some images may show a variety of colors for the LIDAR cable. The drawing should be the final cable colors, but will be validated upon receiving them. (Yellow may have changed to White)
