Door Mirror Wiring Harness, Front, LHD.

The Genuine Porsche Door Mirror Wiring Harness, Front, LHD (Part Number: 91161216403) is an original equipment electrical wiring component designed for selected left-hand-drive Porsche 911 and 911 Turbo (930) models equipped with electrically adjustable exterior mirrors.

Fits:

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984 3.2L
• Porsche 911 1978-1984 3.3L Turbo (930)  

Diagram Ref No 1

This wiring harness forms part of the vehicle's electric door mirror control system, providing the electrical connections between the front luggage compartment wiring, mirror adjustment controls and the relevant door mirror circuits.

Designed for left-hand-drive vehicles, the harness follows the original Porsche wiring arrangement across the front of the vehicle, providing electrical connections for the exterior mirrors on both sides.

The Porsche 911 electric mirror system allows the driver to adjust the exterior mirror positions electrically, helping maintain clear rearward visibility without manually repositioning the mirror glass.

The wiring harness is essential to this operation, carrying electrical signals and power through the appropriate circuits when the mirror adjustment switch is operated.

Over time, original wiring harnesses may deteriorate due to age, moisture exposure, corrosion, repeated movement, damaged insulation or previous electrical repairs.

A damaged harness can interrupt electrical continuity, resulting in intermittent or completely inoperative electric door mirrors.

Replacing a worn or defective wiring harness with a Genuine Porsche component helps restore the original electrical connections, maintain reliable mirror adjustment and preserve the factory wiring arrangement.

Ideal for classic Porsche electrical repairs, electric mirror restoration, front luggage compartment wiring refurbishment and vehicle restoration projects, this Genuine Porsche Door Mirror Wiring Harness provides a factory-specified replacement for compatible left-hand-drive models.

What This Product Does:
The door mirror wiring harness is part of the Porsche 911's electrically adjustable exterior mirror system.

Its primary function is to provide the electrical connections needed for the driver-operated mirror adjustment system.

When the driver operates the mirror adjustment switch, the electrical circuit directs power to the appropriate mirror adjustment motor, allowing the mirror glass to move in the selected direction.

On vehicles with electrically adjustable mirrors on both sides, the wiring arrangement also supports the relevant connections between the left-hand and right-hand mirror circuits.

The front wiring harness is distinct from the individual wiring harnesses located inside the doors.

Its main functions include:

• Providing electrical connectivity: Connects the relevant exterior mirror adjustment circuits.
• Supporting electric mirror adjustment: Carries the electrical signals and power needed to operate the mirror motors.
• Connecting both mirror circuits: Forms part of the original wiring arrangement serving the left and right exterior mirrors.
• Linking the front electrical system: Provides connections between the front fusebox area and the mirror control wiring.
• Supporting mirror selection: Works with the appropriate adjustment and selector switches to operate the selected mirror.
• Maintaining electrical continuity: Provides correctly routed conductors between components.
• Protecting electrical wiring: The harness insulation helps prevent unwanted contact between conductors and surrounding components.
• Maintaining correct wiring routes: Preserves the original cable routing through the front luggage compartment.
• Supporting driver visibility: Enables the electrical adjustment system to position the mirror glass correctly.
• Preserving factory functionality: Maintains the original Porsche electric mirror wiring arrangement.

The harness does not independently operate the mirror motors. It supplies the electrical connections required for the system's switches and motors to work.

Symptoms Of Wear Or Failure:
The original Porsche 911 mirror wiring harness can be affected by decades of temperature changes, moisture exposure, vibration and previous electrical work.

Electrical faults may develop gradually as wire insulation deteriorates or connector contacts become corroded.

Common symptoms of a worn or damaged door mirror wiring harness include:

• Electric mirrors not operating: One or both mirrors may stop responding to the adjustment switch.
• Intermittent mirror adjustment: The mirrors may operate occasionally but fail at other times.
• Mirror movement in only one direction: A damaged conductor or poor connection may interrupt part of the adjustment circuit.
• Both mirrors failing simultaneously: A fault in the shared wiring or power supply may affect both mirror circuits.
• Mirror adjustment working only when wiring is moved: Broken internal conductors or loose connections may create intermittent contact.
• Visible wiring damage: Cracked insulation, exposed conductors or damaged cable sections may indicate deterioration.
• Corroded electrical connectors: Moisture contamination may cause oxidation of electrical terminals.
• Loose connector fittings: Damaged terminals or connector housings may prevent reliable electrical contact.
• Blown fuses: Short circuits caused by damaged insulation or trapped wiring may interrupt the mirror power supply.
• Previous wiring repairs: Poorly joined wires, incorrect connectors or unsuitable replacement cable may contribute to electrical faults.
• Damaged harness routing: Wiring trapped by body panels or incorrectly positioned around the front compartment may become abraded.
• Discoloured or overheated terminals: Excessive electrical resistance or short-circuit damage may cause localised heating.
• Incorrect mirror operation: Wiring faults or previous incorrect repairs may cause adjustment functions to operate unpredictably.

Why Replacement Matters:
Replacing a deteriorated door mirror wiring harness is important for maintaining reliable operation of the Porsche 911's electrically adjustable exterior mirrors.

Damaged wiring can prevent the driver from adjusting the mirrors correctly, potentially affecting rearward visibility.

Loose connections and corroded terminals can also cause intermittent faults that become increasingly difficult to diagnose.

In more serious cases, damaged insulation may allow electrical short circuits, resulting in blown fuses or damage to associated components.

Installing a Genuine Porsche replacement Door Mirror Wiring Harness helps to:

• Restore electric mirror operation: Re-establish the electrical connections needed for mirror adjustment.
• Improve electrical reliability: Replace damaged conductors and deteriorated connections.
• Eliminate intermittent faults: Address broken wires or unreliable connections within a confirmed defective harness.
• Maintain correct mirror adjustment: Support operation of the original adjustment motors and switches.
• Restore the shared mirror circuit: Reinstate the front wiring arrangement serving the appropriate mirror controls.
• Reduce short-circuit risks: Replace damaged insulation that may expose live conductors.
• Maintain correct factory routing: Use the intended left-hand-drive harness arrangement.
• Reduce electrical troubleshooting problems: Replace compromised wiring with an original equipment component.
• Support electrical restoration: Restore wiring damaged through age or previous modifications.
• Preserve vehicle originality: Maintain the factory electrical system configuration.
• Improve long-term serviceability: Restore the original connections used by Porsche's electrical diagrams.
• Maintain Genuine Porsche quality: Use the specified replacement component for compatible applications.

Replacement is particularly recommended when the original harness contains damaged insulation, broken conductors, corroded terminals or previous unsuitable repairs.

Where only a connector or short section of wiring is damaged, a Porsche-approved wiring repair may also be possible. Complete harness replacement is appropriate when deterioration is extensive or a reliable repair cannot be achieved.
