An electrical junction box for an automotive vehicle. The junction box includes an upper cover and a lower cover. The lower cover may be constructed as a unitary one-piece molded body that defines a plurality of separate terminal cavities. Each of the separate terminal cavities is adapted to receive a single wire terminal without a housing connector that has multiple wire-terminal receptacles. In addition, the junction box may include an electrical circuit board and a busbar between the upper cover and the lower cover.
