The SP370-L comes with 1 m (3.28 ft) of cable pre-attached that terminates with MC4 connectors. When ordering the solar panel, specify a cable length in feet that is in addition to the 1 m (3.28 ft) length of pre-attached cable. If you do not desire a longer cable, select "0" (zero) for the cable length, and a set of mating MC4 connectors will be included for you to make your own cable.
