Used OEM Porsche door wiring harness with OEM part number 99661263403, removed from a donor vehicle. This front left harness carries power and signals for window regulators, door locks, and speakers on Porsche 911 and Boxster models equipped with naturally aspirated or turbocharged H6 flat-six engines (2.5L–3.6L). A common failure is broken conductor strands inside the rubber boot between the door and body, leading to intermittent window or lock operation.
