This 6' short cord with a special screw-type sealed connector at one end fits the powerpack's output and a jack plug at the other end to fit the Super Feeder's side input jack.  It can be handy for out-of-weather installation and particularly to adjust the feeder's portion adjustment indoors before any final outdoor installation using outdoor wiring recommendations.  IMPORTANT NOTE:  Only fits ACAC-ODR 12VAC Outdoor Powerpack
