A tailgate assembly for a vehicle includes, among other things, a tailgate configured to pivot relative to a vehicle body between a closed position, a fully open position, and a secondary position that is between the closed position and the fully open position. The assembly further includes a cable device having a tailgate connector and a vehicle connector. The tailgate connector is coupled to the tailgate. The vehicle connector couples to a sidewall of the vehicle in first position to support the tailgate in the fully open position. The vehicle connector couples to the sidewall of the vehicle in a second position to support the tailgate in a secondary position. The first position is vertically below the second position. The assembly still further includes a bracket that blocks removal of the tailgate from the vehicle body when the tailgate is in the fully open position and when the tailgate is in the secondary position.
