Product Information
Fuse Box 10-Pole.
The OE Match Fuse Box 10-Pole is a premium-quality replacement electrical distribution component designed to securely house and connect ten fuse circuits on compatible Porsche models. Manufactured to OE specifications for fit, functionality and durability, this fuse box ensures reliable electrical power distribution while protecting individual circuits from overloads and short circuits.  

Fits:
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Constructed from high-quality heat-resistant insulating materials with corrosion-resistant electrical terminals, the fuse box is engineered to withstand vibration, temperature fluctuations and continuous electrical loads. Precision-manufactured for direct OE-style installation, it restores dependable electrical connections and reliable fuse retention, making it ideal for replacing cracked, corroded or damaged original fuse boxes during restoration or electrical system repairs.  

What This Product Does:
  • Houses and secures ten individual fuse circuits.
  • Distributes electrical power throughout the vehicle.
  • Protects electrical circuits from overloads and short circuits.
  • Provides secure mounting for ceramic fuses.
  • Maintains reliable electrical connections.
  • Supports the correct operation of multiple vehicle electrical systems.
  • Restores factory-style electrical distribution.
  • Forms an essential part of the vehicle's electrical system.

Symptoms Of Wear Or Failure:
  • Intermittent electrical faults.
  • Loss of power to one or more electrical systems.
  • Corroded or burnt fuse terminals.
  • Loose-fitting ceramic fuses.
  • Cracked or damaged fuse box housing.
  • Overheated electrical connections.
  • Difficulty maintaining reliable fuse contact.
  • Flickering lights or intermittent accessory operation.
  • Signs of corrosion caused by moisture.
  • Electrical faults despite serviceable fuses.

Why Replacement Matters:

  • The fuse box is a vital component of the vehicle's electrical system and is continually exposed to heat, vibration, moisture and long-term electrical loading. Over time, the electrical terminals can corrode, connections may loosen and the housing can deteriorate, resulting in increased electrical resistance and unreliable circuit operation.
  • A worn fuse box can cause intermittent electrical faults affecting lighting, ignition, instrumentation, heating and other essential systems. Damaged or corroded terminals may also generate excessive heat, potentially leading to further wiring damage and difficult-to-diagnose electrical problems.
  • Replacing a worn or damaged fuse box restores reliable electrical distribution and proper circuit protection. The OE Match replacement provides factory-style fitment, durable heat-resistant construction and corrosion-resistant terminals, helping ensure dependable electrical performance, improved system reliability and the preservation of your Porsche's original electrical system.

  • Cracked or damaged ceramic housing.
  • Evidence of arcing or burnt connections.
  • Repeated fuse-related electrical issues.

Why Replacement Matters:

  • Fuse racks in classic vehicles are exposed to decades of vibration, heat cycles, moisture and electrical load. Over time, terminals can corrode, contact tension may weaken and the ceramic housing can crack or deteriorate. These issues can increase electrical resistance, create intermittent faults and reduce the reliability of protected circuits.
  • A damaged fuse rack can cause a wide range of electrical problems, from unreliable lighting and accessory operation to increased risk of overheating at electrical connections. Poor contact between the fuse and terminal can also generate excessive heat, potentially damaging wiring and related components.
  • Replacing a worn or damaged fuse rack restores reliable electrical connections and proper circuit protection. An OE Match replacement provides factory-style fitment, authentic appearance and dependable long-term performance, making it an ideal solution for electrical system repairs, restorations and preventative maintenance on your classic Porsche.

Ignition cut-out relay.
This OE Match relay controls ignition cut-off on Porsche 930 Turbo models built between 1975 and 1989. 

Fits
Porsche 930 Turbo 1975 - 1989 

 * Please check and match the part number of your relay in your car before ordering.


What This Product Does

The relay provides electrical switching for the ignition cut-off circuit. It is a separate component from the ignition key switch and lock barrel.



Symptoms of Fault

Possible signs include inconsistent circuit operation, a relay that clicks without producing an output, or heat damage around its connections. These symptoms do not identify the relay alone; wiring and terminal faults should also be investigated.


Why Replacement Matters

Renewal is appropriate when testing confirms worn relay contacts or an internal switching fault. Inspect the socket and associated connections as well, rather than replacing the relay without establishing the cause.


FAQs

What should be checked before replacement?
Confirm the existing relay number, then inspect its seating, connector condition, relevant fuses and earth connections.

Does a clicking relay prove it works?
No. The operating mechanism may respond while damaged contacts fail to pass current correctly.

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

Inline fuses for Footwell heater blower motors.
Sold as a set of 2, with an easy plug-and-play installation. 

Fits:
Porsche 911 - 1984 to 1986
Porsche 911 Turbo 3.3ltr - 1983 to 1986

Diagram ref no 1

This harness set is designed to protect the footwell blowers of the 911 Carrera 3.2 with an inline fuse.

Models from 1984 until April 1986 lacked fusing for the footwell blowers. The fan motors, often prone to failure due to bearing issues, could seize and potentially overheat, leading to damage.

Our inline fuse set offers a direct solution, featuring a 10A inline LED fuse. In the event of a motor short, the fuse will blow and the LED will illuminate, safeguarding your valuable trunk harness.

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.
