Gauge Cluster Printed Circuit Replacement.

The LutzAuto Gauge Cluster Printed Circuit Replacement Kit is a modern, high-quality solution designed to permanently resolve one of the most common electrical failures found in early Porsche 928 (1977–1978) instrument clusters.
From the factory, these vehicles were equipped with a flexible printed circuit foil mounted behind the gauge cluster. Over time, heat, age, and repeated removal cause this foil to become brittle, crack, or tear, leading to intermittent or complete failure of gauges, warning lights, and cluster illumination. Repairing the original foil is often unreliable or impossible.
This LutzAuto kit replaces the fragile factory flex circuit with a durable, modern printed circuit board (PCB) engineered to OEM dimensions for direct fitment. The redesigned PCB restores reliable electrical connections to all gauges and indicators while significantly improving long-term durability.
The kit also includes upgraded LED indicator and illumination lighting, reducing power draw while maintaining a period-correct appearance. Clear installation instructions are provided, making this an ideal solution for restorations, repairs, or preventative upgrades.
Designed and engineered by LutzAuto, this replacement circuit delivers improved reliability while preserving the original function and appearance of the Porsche 928 instrument cluster.

Fits:

  • Porsche 928 4.5L 1977-78


What This Product Does:
  • Replaces the factory flexible printed circuit board in the dashboard instrument cluster.
  • Restores proper electrical connectivity between the vehicle wiring harness and all gauges (speedometer, tachometer, oil pressure, coolant temperature, etc.).
  • Eliminates intermittent gauge failure, flickering needles, or dead indicators caused by old/failing circuit foil.
  • Provides a modern hard-board alternative to the original fragile flex foil, enhancing durability and service life. 

What Is Included In The Kit:
  • New Modern Circuit Boards 
  • New Indicator LED lights
  • New Illumination LED lights 
  • Plugin Wiring and Zipties

Key Features:
  • Direct fitment for 1977–1978 Porsche 928 gauge clusters.
  • Fully redesigned replacement circuit made using modern printed circuit board technology, not delicate flex foil.
  • Includes improved wiring and high-quality components that are less prone to failure than the original factory circuit.
  • Comes with white LED indicator and illumination lights that consume less power while preserving a warm look (instructions included).
  • Detailed installation instructions help ensure a successful upgrade with accurate gauge function and illumination.

Symptoms Of The Original Circuit Failing:
  • Flickering or dead gauge needles
  • Intermittent or non-workings warning lights
  • Speedometer/Tachometer that behaves erratically
  • Cluster backlighting that flickers or does not illuminate
  • Complete loss of multiple cluster functions due to torn flex board

Why Replacement Matters:
  • Restores full instrument functionality — essential for accurate vehicle monitoring and safe driving.
  • Prevents dreaded gauge cluster failures — a common and frustrating issue on early Porsche 928 dashboards.
  • Extends the life of irreplaceable vintage cluster components.
  • Improves illumination and power consumption with modern LEDs.
  • Preserves originality — maintains the classic look while bringing electronics up to a more reliable standard.

Gauge Cluster Printed Circuit Replacement.
The LutzAuto Instrument Cluster Printed Circuit Board Replacement is a precision-engineered solution designed to permanently resolve electrical failures in the Porsche 928 instrument cluster for model years 1979–1981.
Factory-installed flexible printed circuit foils in these vehicles are well known to deteriorate over time. Heat exposure, material fatigue, and repeated handling cause the original foil to crack or lose conductivity, resulting in unreliable gauge readings, warning light failures, and intermittent cluster operation. Attempting to repair the original foil is often ineffective and short-lived.
This LutzAuto replacement kit eliminates those issues by replacing the fragile flex foil with a robust, modern printed circuit board (PCB). Manufactured to exact OEM dimensions and electrical specifications, the PCB restores stable electrical connections to all gauges, indicators, and cluster lighting while significantly improving long-term durability.
Designed for direct installation, the board fits seamlessly into the original instrument cluster housing with no permanent modifications required. The result is a reliable, professional-grade repair that preserves the original appearance and functionality of the dashboard while delivering modern electrical reliability.
Ideal for restorations, daily drivers, and preventative maintenance, this ensures accurate instrumentation and dependable performance from your Porsche 928.

Fits:

  • Porsche 928 4.5L 1979-81

What This Product Does:
  • Replaces the original flex printed circuit foil that connects the vehicle wiring to all gauges and warning lights in the cluster
  • Restores electrical continuity and stability for speedometer, tachometer, oil pressure, coolant temperature, fuel gauge, warning lamps, and backlighting
  • Provides a hard-board PCB solution that is more durable than the factory flex foil
  • Includes wiring mounting provisions and improvements that reduce intermittent electrical faults
  • Retains full OEM appearance and functionality when installed

What Is Included In The Kit:
  • New Modern Circuit Boards
  • New Indicator LED lights
  • New Illumination LED lights
  • Plugin Wiring

Symptoms Of Failure:
  • Erratic gauge behavior (jumping, sticking, or unresponsive)
  • Warning LEDs that fail to illuminate or stay on constantly
  • Cluster illumination issues (dim, flickering, or no light)
  • Sudden loss of multiple gauge functions
  • Dash cluster resets or intermittent faults

Key Features:
  • Direct replacement for Porsche 928 (1979–1982) instrument cluster
  • Modern printed circuit board (PCB) — stronger and more reliable than original flex foil
  • Maintains full original functionality and fitment
  • Restores gauge accuracy and electrical consistency
  • Reduces intermittent faults and cluster electrical issues
  • Easy installation with provided instructions and connector fitment

Why Replacement Matters:
  • A properly functioning instrument cluster is crucial for monitoring engine status, vehicle speed, fuel level, and warning indicators. A faulty cluster can mask critical problems.
  • No more jittery or stuck needles — accurate instrument readings help you drive with confidence.
  • Replacing this known weak point helps maintain the long-term collectability and drivability of classic 928 models.
  • LutzAuto parts are engineered and manufactured for high reliability, making this a superior alternative to attempting fragile repairs of the original flex circuit.
