This allows for the user to connect the Keis male plug (with the short section of cable) to a power output source (portable battery, vehicle power loom, or a power output plug inside a heated vest, bodywarmer or jacket) and divert the power into and through two lengths of cable to two separate Keis 'female' power output sockets. The two long cables are of a slightly different length. This provides approximately 40 cm more cable to the garment furthest from the power source. *These two output plugs can only be connected to a pair of new (post-2020) heated gloves Keis Y Lead Male to Female for Gloves/Insoles
