Abstract: A method for manufacturing a wiring harness of the type having a preformed cable containing a plurality of conductors and arranged in a predetermined path, and having breakouts for certain of the conductors which terminate in electrical contacts at one or more predetermined locations, includes the step of molding an integral frame from insulating mateial. The frame has groups of connector housings for receiving electrical contacts, and located at positions corresponding to the locations of the breakouts, and runners that integrally connect the housings. The method also includes laying the preformed cable in an operative position on the frame so that the cable breakouts are adjacent to the groups of connector housings. After the electrical contacts are inserted into the connector housings, the runners are removed.
