PURPOSE: To easily deal with a design change and to eliminate the splice of a wire. CONSTITUTION: The wire harnesses for a vehicle respectively comprise a plurality of junction boxes 10A to 10E having internal circuits of an electric component unit or an electrical system unit, main lines 20A to 20E wired between the boxes, branch lines 30A to 30P wired between the boxes and the components. The internal circuits of the boxes have branch circuits for distributing all the powers and signals, and through circuits for connecting the internal circuits of the other boxes to each other and the internal circuits of the other boxes to the components. The wires of wire groups for forming the main and the branch lines are all formed of single wires without branching, the main and branch lines are respectively mounted at the ends of the groups with connectors, and connected all to the boxes by the connectors. |
