    What Is This Part?

This is the wiring loom serving the dashboard instrument illumination. Its wires and bulb sockets form the local connections for the lamps that light the gauge faces. It sits within the instrument wiring arrangement and is relevant when repairing damaged illumination wiring or refurbishing the dashboard instruments. 

What Does This Part Do?

  • Supplies the illumination lamps: Provides the wiring connections used to power the gauge lighting.
  • Connects the bulb sockets: Brings the instrument illumination connections together in one harness.
  • Supports instrument lighting repairs: Provides a replacement assembly where the existing illumination loom has deteriorated.

The harness serves the gauge lighting circuit, so any lighting fault should be checked separately from the operation of the gauge itself. 

Why Replace This Part?

Replacement may be appropriate if inspection finds widespread brittle insulation, broken conductors, heat damage or deteriorated connections. Previous alterations can also leave wiring stretched, poorly joined or difficult to reconnect correctly. Whether a local repair or harness replacement is appropriate depends on the extent and position of the damage; the cause should also be addressed. 

A lighting fault alone does not establish that the harness needs replacing. Check the bulbs, supply, earth connections and individual socket contacts before deciding which component requires attention.

When to Replace This Part?

  • Cracked or missing insulation: Exposed conductors or widespread brittleness warrant assessment.
  • Damaged wiring: Replace or repair wiring with confirmed breaks, chafing or stretched connections.
  • Heat-damaged connections: Investigate discolouration or melted insulation and correct the underlying cause.
  • Extensive previous repairs: Consider replacement where multiple poor joints make a sound local repair impractical.
  • During instrument refurbishment: Inspect the loom while access is available; removal alone does not make replacement necessary.

    Base the repair decision on the condition of the wiring and connections rather than age alone. 

    Where Is This Part Fitted?

Location: Behind the dashboard instruments, with its bulb sockets serving the instrument illumination lamps.
