A wire harness device for instrument panels in which when a wire harness for an instrument panel and electrical element units are mounted to the instrument panel, a complicated construction for junction units of the harness like the conventional movable connector is unnecessary; little shift exist in position against the element units; and it is easily fixed to improve its maintainability. A wire harness device comprises a plurality of mounting spouts formed on an instrument panel and having electrical element unit inserted from a front surface side of the mounting spout for mounting on the instrument panel; a plurality of junction units on the instrument panel with connecting portion of the electrical element unit connected to the junction unit; and a wire harness for the instrument panel comprising a plurality of junction units and resilient circuit bodies.
