When working on a vehicle, it is often necessary to move and/or disconnect a wiring harness to facilitate repairs. When reinstalling such a harness, it is absolutely necessary to properly route and fasten it. The routing and installation of wiring harnesses in Porsche vehicles is carefully designed to prevent any contact with other parts of the vehicle that have the potential to damage the harness; therefore, the reinstallation must duplicate the original installation. All wire ties and harness clips should be attached in their original location. All electrical plugs and connectors should be checked to ensure proper engagement. Any insulation pads, bushings, grommets, shields and/or covers removed during repairs must be reinstalled in their original location and in a manner that will not damage the harness or related components.
Failure to properly route and secure a wiring harness after repair can result in unwanted squeaks, rattles or damage to the harness and other parts of the vehicle electrical system. Damage to the harness, if undetected, may result in short circuits and under some cirumstances may result in an electrical fire.
