15. A method for connecting power lines of a fifth wheel coupling arrangement and lines of a trailer, comprising:
providing the fifth wheel coupling arrangement, comprising;
a primary coupling device comprising a base body, a first drive and a connector element; and
a fifth wheel coupling plate having a semitrailer surface and an entry opening;
wherein the base body is configured to be fixed to the fifth wheel coupling arrangement and/or the trailer;
wherein the connector element is displaceable relative to the base body by the first drive in a displacement direction; and
wherein the displacement direction is oriented such that the displacement direction is parallel to a direction of extension of the entry opening of the fifth wheel coupling plate;
providing the semitrailer with a king pin and a secondary coupling device;
displacing the king pin from an uncoupled position to a coupled position relative to the fifth wheel coupling plate; and
connecting the primary coupling device to the secondary coupling device;
wherein 0.1 to 0.5 seconds before the king pin is placed in the coupled position, the drive is activated and/or the primary coupling device is connected to the secondary coupling device.
