    I am looking into buying this product but need to know if I need to buy extra cables to install an extra battery or does it come with everything I need except the extra battery.

    Asked by: Anonymous
    Yes, additional battery cables will be needed such as 21207 or 21212.

    I have a single battery and am looking to add a second battery. Is this switch all I need to accomplish this or do I need other items?

    Asked by: Jeff B
    You will also need additional battery cables.
