Features and Benefits: * Saves memory settings from under the hood * Takes the place of traditional memory savers that use the power outlet, which no longer provides protection on newer vehicles since the outlet is switched * Unique wire piercing tip on clamp connects to battery cable * Clamps can also be used on the back of the battery terminals * Cord is 3’ long Without a battery attached, use the unique wire insulation-piercing tip on the red (positive clamp) to connect the memory saver to the main positive battery cable. Connect the black clamp to a ground source. The light will illuminate to indicate proper connection. Connect a fully charged 9V battery (not included) and the vehicle is protected.
