A wiring system is provided where at least one device connector and at least one device connector are interconnected. The wiring system has at least one main harness with at least one group of wires aligned in a substantially parallel direction, and at least one sub harness with at least one group of wires forming at least one wire crossover. A coupling structure is further provided to couple the main and sub harnesses together to form a complete wiring harness that extends between the first and second device connectors. The wire crossover is provided only in the sub harness, so that the main harness is free of any wire crossovers.

A ground joint connector is provided including at least one connector housing configured to receive and hold at least one terminal of at least one electric wire, and a holder formed from a high-conductivity resin. The holder has a plurality of connector holding portions, each configured to receive and hold the at least one connector housing. The ground joint connector further includes a ground terminal provided on an outer surface of the holder. Each terminal of each electric wire received and held by each connector housing contacts the holder so as to be grounded via the holder and the ground terminal.

A clip for a flat harness is provided that includes an upper plate, a stem portion extending from a vicinity of an end in a longitudinal direction of the upper plate, and at least one projecting portion provided on an outer peripheral surface of the stem portion. The clip further includes a lower plate defining a stem portion insertion hole at a position corresponding to the stem portion, a cylindrical portion extending downwardly from the lower plate at a margin of the stem portion insertion hole. The stem portion is insertable into the cylindrical portion. At least one recessed portion is provided in an inner peripheral surface of the cylindrical portion. The at least one recessed portion is engageable with the at least one projecting portion. A wing-shaped engaging portion extends upwardly from an end of the cylindrical portion, and is engageable with the automobile body.

A grommet is provided that can be engaged in a through hole of the vehicle body panel by a single motion of pushing the grommet in only one direction. The grommet has a small diameter tubular part to tightly engage a wire harness inserted therein, an enlarged diameter part that continues from an end of the small diameter tubular part into the conical tubular shape, and a generally annular vehicle body engaging recess on the outer peripheral face of the enlarged diameter tubular part. The wall thickness of the enlarged diameter tubular part is approximately the same from the position of continuation with the small diameter tubular part to a bottom end of a first side wall of the vehicle body engaging recess. The first side wall is formed to have a turned-back portion from a tip of an inclined part that continues from the conical tubular shape to the bottom end to provide a space at the back face of the first side wall and an inclined part having an inclination is formed from a bottom face of the recess extending toward a second side wall of the recess. A thick wall forms a second side wall portion and a front end face of the enlarged diameter tubular part, and a lip projects from the second side wall toward the first side wall.
