Window motor wiring loom with connector left door. Porsche 911 (1969-1989)

Window motor wiring loom with connector - left door.
This harness assembly is designed as a direct-fit replacement for the factory wiring loom that serves the driver’s-side door switch and window-regulator system on Porsche 911 models. It reconnects the control switch, window motor/regulator and associated connectors with OEM-style routing, connectors and insulation for restored function and reliability.

Fits:

• Function: The harness carries the electrical connections for the power-window mechanism and associated door controls (switches, regulators) in the driver-side door module. Accurate harness fitment ensures consistent switch response, smooth window movement and prevents wiring stress or connector failure.

•  Application: Driver’s-door wiring harness for power window and switch functions

•  Over time, door harnesses are subject to moisture, wear from repeated window operation, hinge motion and vibration. Insulation may crack, connectors loosen or wires may become corroded - resulting in intermittent switch behaviour, non-functional windows or electrical faults. Replacing with a correct-spec harness restores reliable window/switch operation, prevents costly intermittent issues and supports long-term electrical integrity.
