grid is a style of electrical connector with a 24 mm wide flat plastic plug instead of the more familiar round coaxial or red square-end connectors. This results in a strong and jiggle-proof connection that is easy to remove and replace. the blue grid connector is visually very similar to but not interchangeable with the larger blue Anderson connector. Please refer to the specifications to determine whether your 12 volt Kid Trax ride-on uses this style connector.
