A holding apparatus (15) for current and signal conductors of a traction battery of a motor vehicle has a plate-like base body with longitudinal sides (16), transverse ends (17) and a top (18) and bottom (19) extending between the longitudinal sides (16) and transverse ends (17). Elements (20) are arranged on the top (18) and the bottom (19) for guiding and fixing current conductors (12) of the traction battery, and elements (21) are arranged on the other of the top (18) and the bottom (19) for guiding and fixing at least one signal conductor (14) of the traction battery. The base body provides EMC shielding of the signal conductor (14) from the current conductors (12). The plate-like base body has on the opposite longitudinal sides (16) and/or on the opposite transverse sides (17) sections (22) for securing and grounding the holding apparatus on a frame of the motor vehicle.

A wiring module includes a first flexible printed circuit and a second flexible printed circuit that is separate from the first flexible printed circuit. The first flexible printed circuit and the second flexible printed circuit are arranged so as to be continuous in a first direction and are shaped as a band that extends in the first direction. A connector is mounted to each of the first flexible printed circuit and the second flexible printed circuit. The fitting direction in which the connector mounted to the first flexible printed circuit is fitted to a partner connector is different from the fitting direction in which the connector mounted to the second flexible printed circuit is fitted to a partner connector.
