The connection cable has two ends that are intended for the respective glove or underglove (left and right). The cable ends connect the gloves or the undergloves to the two appropriate connectors. These are attached to the vest in the armpit area.
If you buy a vest + a pair of undergloves, the cable is added for free. The connecting cable can also be purchased here as a spare part.
