Abstract: An improved apparatus and method for securing a wire harness to a vehicle trim panel includes the use of an inventive holding clip. The clip has a secured portion which is fixed to the underlying trim panel. A retaining portion is biased against the trim panel, and wires are received in a holding portion between the secured portion and the retaining portion. The clip also includes an entry portion spaced away from the retaining portion which facilitates the movement of the wire under the entry portion to bias the retaining portion away from the trim panel and allows movement of a wire into the holding portion. In a first preferred method, the wires are assembled by first attaching the clips to the trim panel and then routing the wires into the holding portion. In a second preferred method, the wires are routed into the clips prior to the clips being secured to the trim panel. The clips are then secured to the trim panel and at the same time the wires are captured on the trim panel.
