A vehicular cable assembly that is easy to install and allows high transmission rates. This vehicular cable assembly includes at least two unshielded conductive signal lines that are untwisted around each other in a connection region in which the unshielded conductive signal lines are adapted to be connected to an external element and twisted around each other in a region next to the connection region. This vehicular cable assembly also includes a shielding assembly having at least one canal-like receptacle shielding part extending at least along the entire connection region and within which the unshielded conductive signal lines are disposed.
