This cable is meant to connect your heated gloves to a power supply, which can be a battery or a direct connection to the battery of your motorcycle.
The cable is needed if you don't (yet) have a MACNA® jacket that features our Electric Power Guide™.
This is a system of loops inside the jacket through which the cable can be guided, which keeps the cable in place and you comfortable.
If connecting gloves to bike battery, you will also need the Macna 12V Bike Battery Connection Cable
