Fits

• Porsche 914 (1970–1976)
  
  The engine application is the 914/6; check the control-board connection and existing wiring arrangement rather than relying on the broader 914 model listing alone. Check fitment for your specific vehicle (model, year, engine) before ordering.
  
  Diagram ref no 2
  
  What Is This Part?

This is the engine wiring loom that links the engine electrical connections with the control board. It groups the relevant wires into a routed assembly, with colour identification to help distinguish circuits during installation and fault-finding. Taping keeps the wiring together, while rubber sleeves cover the associated terminal connections. It is a replacement option for repairing deteriorated engine wiring or renewing an aged loom during restoration or engine work.

What Does This Part Do?

• Connects the engine and control board: Provides the wiring link to the existing 14-pole male connector.
• Carries electrical circuits: Provides conductive paths between the connected engine equipment and the control board.
• Organises the wiring: Groups the wires into a loom so they can be routed together around the engine.
• Identifies individual wires: Correct wiring colours assist connection checks against the appropriate wiring information.
• Covers terminal connections: Rubber sleeves provide insulation around the associated connections.
  
  Why Replace This Part?

Engine wiring can deteriorate through age, heat, vibration, moisture or abrasion. Insulation may become brittle or split, terminals can corrode, and conductors can fracture where wiring has repeatedly flexed. Previous alterations or poorly made joins can also leave connections that are difficult to inspect and unreliable in use.

Replacement may be appropriate when damage affects several branches or the existing loom can no longer be repaired reliably. An isolated wiring fault may be repairable without replacing the complete harness. Before ordering, check the battery, earth connections, control-board connector and affected electrical components so that a fault elsewhere is not mistaken for harness damage.

When to Replace This Part?

• Cracked insulation: Brittle, split or missing insulation exposes the conductors.
• Heat damage: Melted covering, discoloured terminals or hardened sleeves require investigation.
• Corroded connections: Green deposits, damaged terminals or moisture inside connections warrant inspection.
• Broken or chafed wiring: Damaged branches or exposed strands need repair or replacement.
• Confirmed intermittent faults: Testing identifies a wiring interruption or excessive resistance associated with starting or running problems.
• Extensive previous repairs: Multiple unsuitable joins or altered connections make dependable repair impractical.
  
  Where Is This Part Fitted?

Location: At the engine, linking its electrical connections to the control board through the 14-pole male connector. During fitting, check the existing supports and routing so the loom is not stretched, trapped or left against hot or moving components.

Technical Details

• Connection: Connects to a 14-pole male control-board connector.
• Wiring: Correct wiring colours and taping.
• Connection covering: Rubber sleeves.
• Country of manufacture: Canada.
  
  FAQs

• Can wiring faults appear only when the engine is hot?
  Yes. Heat and vibration can affect damaged wires or marginal connections, so testing may need to reproduce the conditions in which the fault occurs.
• Should every intermittent starting fault lead to harness replacement?
  No. Check the battery, earths, connectors and relevant components first, then confirm whether the harness has a fault.
• Can the existing harness be repaired instead?
  A localised defect may be repairable. Widespread insulation damage, corrosion or unsuitable previous repairs can make replacement more appropriate.

The OE Match complete wiring harness for Porsche 914/6 provides the interconnected wiring assembly used when renewing a deteriorated or extensively modified loom. It features correct wiring colours, connectors, tape and rubber sleeving for the application.

Fits

• Porsche 914 (1970–1976)
  
  This harness is specified for the 914/6 within the 914 model family. Check fitment for your specific vehicle (model, year, engine) before ordering.
  
  Diagram ref no 1
  
  What Is This Part?

A wiring harness, also called a wiring loom, brings multiple electrical circuits together into an organised assembly. Its wires and connectors provide electrical paths between the components connected to it, while the insulation, tape and sleeving keep the wiring separated and bundled. Correct wire colours help identify circuits when comparing connections with the vehicle's wiring information. For a restoration or extensive electrical repair, replacing a deteriorated loom can address damage spread across several branches rather than leaving numerous separate repairs.

What Does This Part Do?

• Connects electrical circuits: Provides wiring paths between the electrical components served by the harness.
• Organises the wiring: Groups individual wires into branches that can be routed through their intended installation positions.
• Supports circuit identification: Correct wiring colours help with tracing connections during installation and fault-finding.
• Insulates and covers wiring: Tape and rubber sleeving form part of the harness covering and terminal protection.
  
  Why Replace This Part?

Replacement may be appropriate when insulation has become brittle, conductors are damaged, or corrosion has spread beyond an isolated connection. Heat damage, abrasion and repeated alterations can leave several areas of an old loom needing attention. Extensive undocumented joins can also make it difficult to establish whether each circuit is connected correctly.

A complete harness should not be the automatic response to an intermittent electrical fault. First establish whether the problem lies in the loom, a connector, an earth connection or the component itself. An isolated defect may be repairable; widespread deterioration provides a stronger reason to renew the assembly.

When to Replace This Part?

• Cracked insulation: Wiring coverings split or expose conductors during inspection.
• Heat damage: Sections of the loom or connector housings show melting, scorching or distortion.
• Physical damage: Wires are chafed, cut, crushed or damaged by rodents.
• Extensive corrosion: Deterioration affects terminals or extends beneath the wire insulation.
• Unreliable previous repairs: Numerous altered connections or poorly secured joins require assessment.
• Confirmed wiring faults: Testing traces intermittent operation, excessive voltage drop or repeated short circuits to the harness.
  
  Technical Details

• Correct wiring colours for the application.
• Application-specific connectors.
• Tape and rubber sleeving.
  
  FAQs

• Should an old harness always be replaced during restoration?
  No. Inspect its insulation, conductors, terminals and previous repairs, then assess whether local repair or replacement is appropriate.
• What should be checked before installation?
  Compare the connections with the vehicle's wiring information and inspect the routing points, clips and grommets. Resolve any cause of previous overheating or abrasion before fitting.

This fuel injection wiring harness from OE Match provides a replacement option when the existing injection loom has deteriorated or suffered damage.

Fits

• Porsche 914 2.0L
• Model listing: 914 (1970-1976)
  
  

Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm the injection-system specification and connector arrangement against the original harness; the model listing alone does not establish compatibility with every engine version.

What This Product Does

The harness groups the wiring serving the fuel-injection system, providing electrical connections between its associated components. Sound wiring and secure terminal contact allow those circuits to carry their intended electrical signals. This is a wiring component rather than a fuel-delivery hose or injector.

Functions

• Connects associated fuel-injection electrical components.
• Carries electrical signals through the injection wiring circuits.
• Groups individual wires into a harness assembly.
  
  

Technical Details

• Brand: OE Match.
• Product reference: 039791761.
• Component type: fuel-injection wiring harness.
  
  

Symptoms of Fault

• Starting difficulties that occur intermittently.

• Running faults that change when wiring moves.
• Cracked insulation or exposed conductors.
• Corroded terminals or damaged connector housings.
• Recurring electrical problems despite replacement of connected components.
  
  

These signs are not conclusive evidence of harness failure. Check the battery, earth connections, terminals and relevant circuits before deciding which component requires replacement.

Why Replacement Matters

Age, engine-bay heat and vibration can leave insulation brittle, damage conductors or weaken connections. Renewing a confirmed faulty harness addresses deteriorated wiring rather than repeatedly replacing components affected by an unreliable connection. Replacement may also be appropriate during restoration where extensive corrosion or numerous previous repairs make local repairs unsuitable.

FAQs

Can wiring problems resemble a failed injection component?
Yes. A damaged wire or poor terminal connection can interrupt a circuit and produce similar running symptoms. Test the wiring as well as the connected component.

Should a damaged section be repaired or the harness replaced?
An isolated defect may be repairable using suitable methods. Widespread insulation damage, corrosion or unreliable joins can justify harness replacement after inspection.

What should be checked before fitting?
Compare the original loom, connector layout and vehicle specification. Inspect adjoining connections and earth points so that existing faults are not left unresolved.
