Electrical connectors are critical to the reliable operation of various door-mounted systems including central locking, speakers, mirror circuits, window mechanisms and auxiliary electrical equipment. Over time, connector housings can become damaged, brittle or corroded, resulting in poor electrical connections and intermittent faults.

Manufactured to OE Match standards, this connector housing provides the correct fit, terminal retention and durability required to restore factory-quality electrical performance.

What Does the Wiring Connector Housing Do?

The connector housing serves as a protective and locating interface for electrical terminals within the wiring loom.

Its primary functions include:

• Securing electrical terminals
• Connecting door wiring circuits
• Protecting electrical contacts
• Maintaining terminal alignment
• Preventing wiring separation
• Supporting reliable signal transmission
• Protecting against vibration-related electrical faults

Without a correctly functioning connector housing, electrical circuits may become unreliable or fail altogether.

Why Do Wiring Connector Housings Fail?

Electrical connectors are subjected to years of environmental exposure and repeated vibration.

Common causes of failure include:

• Age-related plastic deterioration
• Heat cycling
• Moisture ingress
• Corrosion
• Broken locking tabs
• Damage during electrical repairs
• Terminal overheating
• Wiring loom stress

As the housing deteriorates, terminals may loosen or become misaligned, causing poor electrical continuity.

Symptoms of a Failing Connector Housing

Common warning signs include:

• Intermittent electrical faults
• Loss of power to door-mounted components
• Loose wiring connections
• Visible cracks in the housing
• Broken retaining clips
• Corrosion around the connector
• Electrical components operating intermittently
• Wiring movement within the connector body

These faults can often be traced back to damaged connector housings rather than the electrical components themselves.

When Should the Connector Housing Be Replaced?

Replacement is recommended when:

• The housing is cracked or damaged
• Locking tabs are broken
• Electrical faults are traced to the connector
• Corrosion is present
• Wiring repairs are being carried out
• Restoring a door wiring loom
• Replacing damaged terminals
• Completing a vehicle restoration

Many Porsche specialists replace damaged connector housings during electrical repairs to prevent future reliability issues.

Why Replacement Matters

A damaged connector housing can lead to recurring electrical problems and unreliable component operation.

Benefits of replacement include:

• Improved electrical reliability
• Secure terminal retention
• Reduced risk of intermittent faults
• Improved wiring loom integrity
• Professional repair quality
• Enhanced durability
• Factory-style fitment
• Long-term reliability

Replacing worn connectors is often a simple and cost-effective solution to persistent electrical issues.

5-Pin Wiring Connector Housing - Door Mirror Switch

Restore a secure and reliable electrical connection to your Porsche door mirror switch with this OE Match 5-Pin Wiring Connector Housing. Designed for Porsche 964 and Porsche 993 models, this connector housing fits directly onto the door wiring loom and connects the vehicle wiring to the electric door mirror adjustment switch.

Fits:

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 964 (911) TURBO 3.3L 1991-93
• Porsche 964 (911) TURBO 3.6L 1991-93
• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97
• Porsche 993 (911) C2S 1994-97

• Porsche 993 (911) TURBO 1994-96
• Porsche 993 (911) TURBO S 1994-97

Although small and often overlooked, this connector plays a critical role in the operation of the electric mirror system. It ensures that electrical signals are transferred reliably between the vehicle wiring harness and the mirror control switch, allowing precise adjustment of the door mirrors.

Over time, connector housings can become brittle, damaged or corroded, resulting in poor electrical connections, intermittent mirror operation or complete loss of functionality. Replacing a damaged connector housing helps restore reliable electrical performance while maintaining the integrity of the factory wiring loom.

What Does the Door Mirror Switch Connector Housing Do?

The connector housing serves as the interface between the door wiring loom and the mirror adjustment switch.

Its primary functions include:

• Securing electrical terminals
• Connecting the door loom to the mirror switch
• Protecting electrical contacts
• Maintaining correct terminal alignment
• Ensuring reliable electrical communication
• Supporting electric mirror adjustment functions
• Preventing loose wiring connections

Without a secure connector, the mirror switch cannot reliably control the door mirror motors.

Why Do Connector Housings Fail?

Electrical connector housings are exposed to heat, vibration and environmental conditions throughout their service life.

Common causes of failure include:

• Age-related plastic deterioration
• Heat cycling
• Moisture ingress
• Corrosion of terminals
• Broken locking tabs
• Damage during switch removal
• Wiring repairs
• General wear and tear

As the housing deteriorates, terminals can become loose or poorly aligned, affecting electrical performance.

Symptoms of a Failing Connector Housing

Common warning signs include:

• Electric mirrors not operating correctly
• Intermittent mirror adjustment
• Loose switch connections
• Broken connector locking tabs
• Visible damage to the housing
• Corroded terminal area
• Wiring movement within the connector
• Mirror adjustment working only in certain directions

These issues often indicate a poor electrical connection rather than a fault with the mirror switch itself.

When Should the Connector Housing Be Replaced?

Replacement is recommended when:

• The housing is cracked or broken
• Locking tabs are damaged
• Electrical connections become unreliable
• Restoring a damaged wiring loom
• Replacing the mirror adjustment switch
• Corrosion is present
• Carrying out electrical repairs
• Completing a vehicle restoration

Many Porsche restorers replace damaged connectors to ensure long-term electrical reliability.

Why Replacement Matters

A damaged connector housing can cause frustrating electrical faults and intermittent system operation.

Benefits of replacement include:

• Improved electrical reliability
• Secure switch connection
• Correct terminal positioning
• Reduced risk of electrical faults
• Improved mirror operation
• Preservation of the original wiring loom
• Professional repair quality
• Long-term durability

Replacing worn electrical connectors is often one of the simplest ways to eliminate recurring electrical issues.

ECU and Ignition system conversion kit.

Fits
Porsche 964 C2 - 1989 to 1994
Porsche 964 C4 - 1989 to 1994

This kit is a modern update to the 964 (911) ignition system. This system takes the management of the car into the digital age and allows greater control over ignition and fueling.

The kit will replace your restrictive old fashioned air flow meter (barn door) with a modern MAP sensor managed by intake pressures.

The kit is delivered ready to use with a PPT ignition map. We have maps for 3.6 and 3.8 conversions, and either can be pre-installed for you.

Our latest kit now comes with an upgraded ECU and can run a wide band sensor (oxygen sensor).
Our kits include this capability but the sensor needs to be ordered separately.

While developing the upgraded ECU we also changed our intake pipe; this now works with the factory airbox, gives a stock appearance in the engine bay and houses the map sensor and air temp sensor out of sight.

Kit includes:
• Delta 700 ECU
• Direct plug in wiring loom
• Map Sensor and air temp sensor
• Air intake pipe
• 6 Bosch injectors
• Vacuum pipe and T connector
• Support and service by PIE Performance
• Can Bus data connection tool

All our kits are 100% reversible, with no need to drill or alter components, we utilise what already exists
