The flasher relay is responsible for interrupting and restoring electrical current at precise intervals, creating the flashing action required for turn signals and hazard lights. Reliable operation of this component is essential for vehicle safety, visibility and legal road compliance.
What This Product Does:
- Controls the flashing operation of the turn signal indicators.
- Operates the hazard warning light system.
- Maintains the correct indicator flash rate.
- Regulates electrical current flow to the signalling circuits.
- Helps ensure other road users are aware of driver intentions.
- Supports safe and legal vehicle operation.
- Provides reliable indicator and hazard light functionality.
Symptoms Of Wear Or Failure:
- Turn signals not operating.
- Hazard warning lights failing to function.
- Indicators flashing too quickly (hyperflashing).
- Indicators flashing too slowly.
- Intermittent indicator operation.
- Indicators remaining illuminated without flashing.
- Audible clicking noise absent or irregular.
- Complete failure of turn signal and hazard light systems.
Why Replacement Matters:
- Flasher relays are subjected to repeated electrical switching cycles, heat and vibration throughout their service life. Over time, internal contacts and electronic components can wear, causing inconsistent operation or complete failure.
- A faulty flasher relay can prevent turn signals and hazard lights from functioning correctly, reducing vehicle visibility and increasing the risk of accidents. In addition to creating a safety concern, defective indicators may also result in the vehicle failing roadworthiness inspections or not complying with legal requirements.
- Replacing a worn or malfunctioning flasher relay restores correct indicator and hazard light operation, ensuring safe communication with other road users. An OE Match replacement provides factory-style fitment, reliable performance and long-term durability, helping maintain the safety and functionality of your Porsche's electrical system.

Although small and often overlooked, the air conditioning relay plays a critical role in the operation of the vehicle's climate control system. A faulty relay can prevent the air conditioning system from functioning correctly, leading to intermittent cooling, compressor failure to engage or complete loss of A/C operation.
Manufactured to OE Match standards, this replacement relay provides dependable performance and factory-correct fitment for maintenance, fault diagnosis and restoration projects.
What Does the Air Conditioning Relay Do?
The air conditioning relay acts as an electrically controlled switch within the A/C system.
Its primary functions include:
- Controlling power to the air conditioning system
- Activating the compressor circuit
- Supporting blower motor operation
- Protecting electrical circuits
- Managing high-current loads safely
- Ensuring reliable A/C engagement
- Supporting climate control functionality
The relay allows low-current control circuits to safely operate higher-current air conditioning components.
Why Do Air Conditioning Relays Fail?
Like all electrical relays, air conditioning relays experience wear throughout their service life.
Common causes of failure include:
- Contact wear
- Heat-related deterioration
- Electrical arcing
- Internal corrosion
- Moisture ingress
- Age-related component fatigue
- Voltage fluctuations
- Extended periods of operation
Over time, relay contacts can become worn or contaminated, resulting in unreliable operation.
Symptoms of a Faulty Air Conditioning Relay
Common warning signs include:
- Air conditioning not switching on
- Compressor failing to engage
- Intermittent cooling performance
- Blower operation faults
- Clicking noises from the relay
- Unreliable climate control operation
- Electrical system fault diagnosis issues
- Complete A/C system inactivity
Because relay failures can mimic other air conditioning faults, they are often checked early during diagnosis.
When Should the Air Conditioning Relay Be Replaced?
Replacement is recommended when:
- Diagnosing air conditioning faults
- Compressor engagement becomes intermittent
- Air conditioning stops functioning
- Electrical testing identifies relay failure
- Restoring a Porsche 911
- Performing preventative maintenance
- Refurbishing the climate control system
Many specialists replace ageing relays during electrical restoration work to improve long-term reliability.
Why Replacement Matters
Replacing a failing relay can restore proper operation of the entire air conditioning system.
Benefits include:
- Reliable compressor engagement
- Consistent cooling performance
- Improved electrical reliability
- Reduced risk of intermittent faults
- Enhanced climate control operation
- Improved driving comfort
- Better diagnostic accuracy
- Long-term system dependability
For classic Porsche 911 models, maintaining reliable electrical components helps preserve both usability and originality.

Type: 6-pole electrical connector
Contents: Male and female connectors
What Does the Multi Plug Socket Do?
The 6-pole multi plug provides a detachable electrical connection between sections of the vehicle wiring.
Its six-pole design allows multiple electrical circuits to pass through a single connector while keeping the wiring organised and providing a connection that can be separated when servicing electrical components or the wiring loom.
Why Do Electrical Connectors Fail?
Electrical connectors on classic Porsche models can deteriorate after decades of heat, vibration and previous maintenance.
Common problems include:
- Brittle or cracked connector housings
- Broken retaining sections
- Corroded electrical terminals
- Loose connections
- Heat damage
- Previous wiring repairs
- Damaged or incorrectly fitted terminals
A deteriorated connector can cause intermittent electrical faults even when the surrounding wiring appears serviceable.
When Should It Be Replaced?
Replace the multi plug socket if the housing is cracked, melted, badly worn or no longer holds the electrical connections securely.
If diagnosing an intermittent electrical problem, also inspect the terminals and surrounding wiring for corrosion, heat damage or broken conductors before replacing the connector housing.
Checks Before Installation
Before fitting, check:
- Existing connector matches the 6-pole configuration
- Wiring terminals are clean and undamaged
- Wires are securely attached to their terminals
- No corrosion is present
- Connector orientation is correct
- Wiring is installed in the correct terminal positions
Record the original wire positions before dismantling the existing connector to avoid incorrect reconnection.

The red fuel pump relay is an replacement designed to control and protect the fuel pump circuit on classic Porsche 911 models from 1975–89. Built to the same electrical specifications as the original red relay (previously 91161510801), it ensures reliable activation of the fuel pump, stabilises current delivery, and prevents pump operation under unsafe conditions.
Fits:
Porsche 911 1975 - 1989
Porsche 911 Turbo 3.0/3.3L 1975 - 1989
* Please check and match the part number of your relay in your car before ordering.
This red fuel pump relay:
• Controls power supply to the fuel pump, ensuring it only runs when the engine is operating or cranking
• Provides essential electrical protection by preventing voltage spikes and reducing load on ignition components
• Ensures stable fuel delivery for smooth starting, reliable idle and consistent engine operation
• Replaces weak, intermittent or failed original relays that can cause no-start symptoms, stalling or fuel-pressure loss.
A failing red fuel pump relay can cause:
• Intermittent or complete no-start conditions
• Engine stalling, especially when warm Loss of fuel pressure leading to hesitation or uneven running
• Electrical overheating or relay chatter Fuel pump running continuously - a significant safety risk
Replacing the relay restores reliable fuel delivery and ensures the fuel pump operates exactly as Porsche intended.
