There are 3 small 1/4" gold tipped jack cables with right angle connectors to join pedals close together, and 3 larger ones for pedals either external to the board or placed in a loop in the case. All power is set up for you, just plug the power adapter included) into the dedicated power input and connect the daisy chain points into your pedals.
