An electrical wiring system is described for providing required and other electrical signals and functions between a truck tractor and a trailer coupled for towing to the tractor. The tractor has an operator cab and may include a sleeper compartment (box) behind the cab. The wiring system provides efficiencies in manufacture of the tractor, particularly when it includes a sleeper box which the tractor manufacturer may offer in a range of lengths. The wiring system includes a cable module for the cab and a standard-length cable module for the sleeper box. The cab cable module terminates at its rear end in a connector to which can be connected either a socket assembly for a removable tractor-to-trailer cable unit having end connectors conforming to an applicable Standard, or a connector at the forward end of the sleeper box cable module, or a tractor-to-trailer cable unit which is more permanently connected to the tractor. The rear end of the sleeper box cable module terminates in a connector which can be a duplicate of the connector of the cab cable module.

1. In a truck tractor having an operator cab mounted on a forward position of a tractor chassis and a sleeper box mounted on the chassis at the rear of the cab, an electrical wiring arrangement providing required electrical connections for a trailer which may be coupled to the tractor at the rear of the chassis behind the sleeper box, the wiring arrangement comprising a first multi-conductor cable connectible to an electrical connection panel in the cab and terminating at a rear end thereof in a first connector of generally female type which includes a terminal for each respective cable conductor and which is fixed to and opens rearwardly from the cab, and a second multiconductor cable of standard length terminating at one end in a second connector of generally male type connectible to the aforesaid first connector and terminating at its other end in a third connector of generally female type which is similar to the aforesaid female first connector, and which is mounted in a rear portion of the sleeper box to open rearwardly therefrom.
