Product Information
Product Information

Turn signal flasher relay. 12 VOLT
Genuine Porsche 12-volt indicator flasher relay for the specified classic 911, 912 and 356 applications. It controls the switching cycle that makes the direction indicator lamps flash.

Fits

  • Porsche 356 B/C M/CARRERA 2000GT 1960 - 1965
  • Porsche 911 >>1968

What This Product Does

The flasher relay repeatedly switches the indicator circuit on and off while a direction signal is selected. This component serves the indicator lighting system; it is not the horn relay, despite appearing within the horn relay assembly diagram.


Functions

  • Cycles the electrical supply to the direction indicator lamps.
  • Provides the flashing action used when signalling a turn.


Technical Details

  • Brand: Genuine Porsche.
  • Electrical specification: 12 VOLT.
  • Supplied part references: 64461334210 and 64461334211.
  • 911 diagram entry: 64461334210, direction indicator flasher relay, with a note specifying use up to 1968.
  • 356 B/C diagram entry: 64461334211, 12-volt flasher relay, application M/CARRERA2000 GT.


Symptoms of Fault

  • Intermittent indicator operation.
  • Relay activity without the expected lighting function.
  • Corrosion, loose connections or heat damage around the relay socket.


Why Replacement Matters

Renewing a relay confirmed to be faulty can restore the indicator circuit's switching function. Inspect the fuse, terminals, wiring and earth connections first, as faults elsewhere in the circuit can produce similar symptoms. Replacing the relay alone will not resolve damaged wiring or poor socket contact.


FAQs

What should be checked before replacing the relay?
Inspect the fuse condition and specified rating, relay seating, connector condition and earth connections.

Can an intermittent fault come from a connection?
Yes. Loose or corroded terminals can interrupt the circuit, so the surrounding connections should be checked during diagnosis.

Does the 356 listing cover every electrical specification?
No. The supplied application identifies a 12-volt relay for M/CARRERA 2000GT models. Confirm the vehicle's voltage and existing relay specification rather than relying on the model name alone.

Product Information

Turn signal flasher relay. 12 VOLT
OE Match supplies this 12-volt direction-indicator flasher relay for selected classic Porsche 911, 912 and 356 B/C applications. It is a replacement component for the indicator flashing circuit.

Fits

  • Porsche 356 B/C M/CARRERA 2000GT 1960-65
  • Porsche 911 >>1968

What This Product Does

The relay controls the repeated switching of the direction-indicator lamps, producing their flashing operation when the indicator circuit is activated.


Functions

  • Controls flashing within the direction-indicator circuit.
  • Replaces the existing flasher relay on a compatible vehicle.


Technical Details

  • Brand: OE Match.
  • Electrical specification: 12 VOLT.
  • Supplied references: 64461334210 and 64461334211.
  • The 911 diagram identifies 64461334210 as the direction-indicator flasher relay, with an application note through 1968.
  • The 356B / 356C diagram identifies 64461334211 as a 12-volt flasher relay for M/CARRERA2000 GT.


Symptoms of Fault

Intermittent indicator operation or a loss of circuit output can warrant investigation. Corroded connections, loose terminals and heat damage around the relay socket may also contribute to electrical faults, so these signs do not establish that the relay itself has failed.


Why Replacement Matters

Renewing a relay confirmed to be defective addresses the switching fault within the indicator circuit. Check the associated wiring and connections before fitting a replacement, as unresolved electrical faults may remain after the relay is changed.


FAQs

What should be checked before replacement?
Inspect the fuse, relay seating, terminal condition and earth connections, then confirm the original reference and vehicle specification.

Does this suit every 356 B/C?
The supplied application specifies M/CARRERA 2000GT and a 12-volt system. Do not assume compatibility from the model designation alone.

Check fitment for your specific vehicle (model, year, engine) before ordering.

About Relays / Fuses

Relays and Fuses – Electrical Protection and Performance for Porsche Vehicles

Relays and fuses are critical components in your Porsche’s electrical system, ensuring that power is delivered safely and reliably to every circuit. From the ignition and lighting systems to the fuel pump and cooling fans, these components protect wiring and electrical modules from overload, short circuits, and potential failure.

At Design911, we stock a comprehensive selection of genuine and high quality relays and fuses for all Porsche models - including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is built to the highest standards to ensure dependable performance and precise compatibility with your vehicle’s electrical system.

What Do Relays and Fuses Do?

Fuses act as the first line of defence in your vehicle’s electrical circuits. They break the circuit when current exceeds safe levels, preventing damage to components or wiring.

Relays
act as electronic switches that control high-current devices using low-current signals. They allow systems like headlights, fuel pumps, fans, and wipers to operate efficiently without overloading the control switches.

Together, they form a vital network that maintains safety, functionality, and reliability across your Porsche’s electrical system.

Why Do Relays and Fuses Fail?

Over time, electrical components are subject to wear, heat, and environmental factors that can lead to failure. Common causes include:

  • Overheating or overcurrent loads blowing the fuse.
  • Aging or corroded relay contacts leading to intermittent operation.
  • Moisture ingress or corrosion within the fuse box or relay socket.
  • Vibration or mechanical stress loosening connections.
  • Electrical short circuits caused by wiring faults or damaged insulation.

Symptoms of faulty relays or fuses can include malfunctioning lights, non-start conditions, intermittent accessory operation, or completely dead electrical systems.

Why Replace Faulty Relays and Fuses?

Replacing worn or damaged relays and fuses is essential to maintain your Porsche’s electrical integrity and prevent more serious system failures. Using quality replacements ensures proper current flow, system protection, and long-term reliability.

Benefits of replacement include:
Restored function of electrical systems and accessories.
Protection from wiring damage or electrical fires.
Enhanced safety and dependability.
High-level quality and fitment for lasting performance.

Every relay and fuse in this range is precision-tested and manufactured to match factory specifications, ensuring seamless compatibility and peace of mind on the road.
