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:
Porsche 911 - 1969 to 1989

• 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.

The Genuine Porsche Wiring Harness for Front Turn Signal 90161204700 is a replacement electrical wiring harness for the right-hand front turn signal/indicator on compatible Porsche vehicles.
(2 Pieces Required For 69 Model For Left/Right)
Fits:
- Porsche 911 2.0L 09/68-08/69 - left/right, 2 pcs. req.
- Porsche 911 2.0-2.7L 08/69-07/73 - right, 1 pcs. req.

Diagram Ref No 10
The harness provides the electrical connection required for the front indicator lamp to operate correctly. It carries electrical power and the necessary circuit connection between the vehicle wiring system and the right front turn signal assembly.
Age, corrosion, heat, moisture, previous repairs and damaged connectors can all cause an older wiring harness to become unreliable. Replacing a deteriorated harness helps restore dependable indicator operation and avoids intermittent electrical faults caused by damaged wiring or poor connections.
What This Product Does:
The wiring harness forms the electrical connection between the vehicle and the right front indicator assembly.
Its functions include:
- Supplying the electrical circuit to the front turn signal
- Connecting the indicator lamp to the vehicle wiring system
- Maintaining reliable electrical continuity
- Providing secure connections at the lamp assembly
- Supporting consistent indicator operation
- Keeping the original exterior lighting circuit correctly connected
When the turn signal is activated, the electrical circuit allows the right front indicator to flash and signal the driver's intended direction to other road users.
Symptoms Of Wear Or Failure:
Common signs of wiring or connector deterioration include:
The indicator bulb, lamp assembly and other parts of the circuit should also be checked before concluding that the harness itself has failed.
Why Replacement Matters:
Turn signals are essential safety and communication devices.
Replacing a damaged right-front indicator wiring harness helps:
- Restore reliable indicator operation
- Maintain consistent electrical continuity
- Correct intermittent electrical faults
- Replace damaged or corroded terminals
- Eliminate brittle or unsafe wiring
- Reduce the risk of short circuits
- Maintain correct exterior lighting operation
- Restore original-style electrical connections
- Improve reliability compared with deteriorated temporary repairs
A turn signal that operates only intermittently cannot provide a dependable indication to other road users.

Wiring Harnesses – Precision Electrical Connectivity for Porsche Vehicles
Wiring harnesses are the backbone of your Porsche’s electrical system. They connect and deliver power between critical components - from lighting and sensors to engine management and infotainment systems - ensuring everything functions as designed. A properly fitted harness guarantees reliable electrical performance, signal integrity, and safety throughout the vehicle.
At Design911, we supply a wide range of genuine and high-quality wiring harnesses for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each harness is meticulously engineered offering precision, reliability, and durability as intended
What Do Wiring Harnesses Do?
A wiring harness is a complex assembly of wires, connectors,
and terminals designed to:
- Transmit
power and data between electrical systems.
- Protect
electrical circuits with insulated, organised routing.
- Simplify
installation and maintenance by combining multiple wires into one
unified assembly.
- Ensure correct communication between sensors, ECUs, lights, and other modules.
In modern Porsches, wiring harnesses play a vital role in enabling advanced technologies — from adaptive lighting and traction control to comfort and entertainment systems.
Why Do Wiring Harnesses Fail?
Even though designed for longevity, wiring harnesses can
degrade or fail due to:
- Heat
exposure or engine vibration causing insulation wear.
- Moisture
ingress or corrosion in connectors and terminals.
- Rodent
damage or physical abrasion from engine movement.
- Electrical
overloads or short circuits damaging internal wiring.
- Previous repairs or poor modifications affecting performance.
Signs of a failing wiring harness include flickering lights, intermittent electrical faults, dashboard warnings, or complete system failure.
Why Replace Faulty Wiring Harnesses?
Replacing a damaged wiring harness restores proper electrical performance, eliminates intermittent issues, and prevents costly damage to control modules or sensors.
Benefits of replacement include:
- Restored power delivery and communication across systems.
- Improved reliability and protection against shorts or fires.
- Elimination of diagnostic faults and warning lights.
- Precision-fit installation with manufacturer-standard components.
Each harness in this range is built using high-grade materials and connectors, ensuring accurate fitment, corrosion resistance, and long-term dependability.
