Diagram Ref No 9 

What This Product Does

This spacer is installed as part of the central electrical-system mounting arrangement. It establishes separation between the relevant assembly components and assists with retaining the intended factory positioning during installation.

Functions

  • Creates the required clearance between adjoining assembly parts
  • Helps locate the associated components in their designed positions
  • Reduces unintended contact within the mounting arrangement
  • Replaces an absent, worn or deformed original spacer

Symptoms of Fault

  • The original spacer is absent during dismantling or inspection
  • Cracking, distortion or other visible deterioration is present
  • Associated parts no longer align or seat as intended
  • Unwanted clearance, movement or contact is found around the mounting points

Why Replacement Matters

A serviceable spacer helps preserve the original physical layout of the central electrical assembly. Renewing a missing or damaged item supports accurate alignment and prevents adjoining pieces from being assembled with incorrect clearance. Confirm the required quantity before installation, as the exploded diagrams specify two for the 964 assembly and one for the 993 assembly.

FAQs

  • Is this an electrical component?
    No. It is a mechanical spacer used in the mounting arrangement for the central electrical system.
  • How many spacers are required?
    The supplied diagrams list two for the Porsche 964 assembly and one for the Porsche 993 assembly. Check what is required for the individual repair.
  • How can suitability be confirmed?
    Match part number 96461023200 to the existing component and verify the model, production year and vehicle details before fitting.

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.
