The OE Match engine harness for Bosch alternator replaces the engine wiring on Porsche 911 1970–71 models with the 2 Pole connector arrangement. It is supplied with new connectors, housings, connector boots and an engine tin square grommet for engine wiring repairs and restoration. Manufactured to original specs.

Fits

• Porsche 911 1970–71 — for Bosch alternator with 2 Pole connector.
  
  Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm the alternator type and connector arrangement, particularly if the charging system has been changed previously.
  
  What Is This Part?

This is the engine wiring harness for the Bosch alternator installation, grouping the relevant electrical wiring into an organised loom. Its connectors and housings provide the connection points, while the boots cover the terminal areas and the square grommet protects the wiring where it passes through the engine tin. The harness is manufactured to original specifications and made in Canada. It provides a replacement option when the existing loom has deteriorated or accumulated repairs that make further local repairs impractical.

What Does This Part Do?

• Connects the engine wiring: Provides the wiring arrangement for the specified Bosch alternator application.
• Groups the circuits: Keeps the engine wiring together as a loom rather than separate, unsupported wires.
• Provides connection points: New connectors and housings replace the corresponding ageing connection components.
• Covers terminal areas: Connector boots provide covering around the electrical connections.
• Protects the engine tin passage: The square grommet separates the wiring from the edge of its opening.
  
  Why Replace This Part?

Engine wiring can deteriorate through age, heat, vibration and abrasion. Cracked insulation, fractured wires or corroded connections can interrupt a circuit or introduce resistance, potentially contributing to intermittent electrical faults or poor charging. Replacement is appropriate when inspection and testing identify damage within the harness, rather than simply because a charging fault is present.

A replacement loom may also be useful during restoration when the original wiring has widespread deterioration, unsuitable joins or damaged connector housings. Check the battery, earth connections, alternator and regulator as part of diagnosis so that a fault elsewhere is not mistaken for harness failure.

When to Replace This Part?

• Damaged insulation: Cracking, brittleness, chafing or exposed conductors are visible.
• Heat damage: Wiring, boots or connector housings show melting or scorching; investigate the cause before fitting a replacement.
• Deteriorated connections: Terminals are corroded, loose or no longer retained properly in their housings.
• Confirmed circuit faults: Electrical testing identifies a broken conductor or excessive resistance in the loom.
• Unsuitable previous repairs: Multiple damaged or poorly secured joins make dependable local repair impractical.
• Removal reveals damage: Engine or alternator work exposes worn wiring or a damaged engine tin grommet.
  
  Where Is This Part Fitted?

Location: In the rear engine compartment, forming part of the engine wiring arrangement for the Bosch alternator installation. The supplied square grommet fits at the wiring passage through the engine tin.

Fits

• Porsche 911 1970–71 — with Motorola alternator.
  
  These broader model classifications do not extend this harness's application beyond Porsche 911 1970–71 with a Motorola alternator. Confirm the alternator currently fitted, particularly if the charging system has previously been changed.
  
  Check fitment for your specific vehicle (model, year, engine) before ordering.
  
  Diagram ref no 20
  
  What Is This Part?

This is the engine wiring loom specified for the Motorola alternator installation. The harness forms the electrical connection between the engine and the engine-compartment fuse-panel wiring, grouping individual circuits into a routed assembly. Its conductors and connections carry electricity between the connected components and the vehicle wiring. During restoration or engine work, its condition should be assessed alongside the terminals, earth connections and surrounding wiring.

What Does This Part Do?

• Connects engine wiring: Links the engine electrical circuits to the engine-compartment wiring connection.
• Serves the Motorola installation: Provides the engine harness application specified for this alternator arrangement.
• Groups individual circuits: Keeps the engine wiring together as a loom for routing and connection.
• Replaces deteriorated wiring: Allows a damaged engine harness to be renewed as an assembly rather than retaining multiple unreliable repairs.
  
  Why Replace This Part?

Engine-bay heat, vibration and age can leave insulation brittle, damage conductors or loosen connections. Corroded or poorly secured terminals can introduce electrical resistance, causing voltage loss and intermittent charging faults. Replacement may be appropriate where inspection confirms widespread deterioration, damaged connections or previous repairs that cannot be put right satisfactorily.

A charging warning or flat battery does not establish that the harness is faulty. Check battery condition, earth straps, alternator connections and charging-system operation before deciding which component needs replacing. A sound harness does not need automatic replacement whenever the alternator is removed.

When to Replace This Part?

• Cracked insulation: Brittle, split or missing covering exposes the conductors.
• Heat damage: Melted insulation, discolouration or burnt connections require investigation.
• Damaged wiring: Chafed, cut or fractured conductors are found during inspection.
• Corroded terminals: Connections are damaged or no longer make secure electrical contact.
• Confirmed electrical loss: Continuity or voltage-drop testing identifies a fault within the harness.
• Unsatisfactory previous repairs: Multiple damaged joins or altered connections make reliable repair impractical.
  
  Where Is This Part Fitted?

Location: In the rear engine compartment, running between the engine electrical connections and the engine-compartment fuse-panel harness. During fitting, check routing and supports so the loom is not stretched, trapped or left rubbing against adjacent parts. Disconnect the battery before disturbing alternator electrical connections.

Technical Details

• Country of manufacture: Canada.
• Electrical application: Engine harness for Motorola alternator installation.
  
  FAQs

• Should I replace the harness for a charging fault alone? No. Inspect the wiring and connections, then test the charging system to establish the cause.
• Can an individual damaged wire be repaired? A localised defect may be repairable using suitable automotive wiring methods. Widespread insulation damage or corrosion may justify harness replacement.

Why Replacement Matters

Ageing insulation, fractured conductors and corroded connections can interrupt electrical circuits. Replacing a deteriorated loom addresses damaged wiring as an assembly rather than adding further joins to extensively repaired sections. Check battery connections, earth straps and adjoining connectors as part of the same diagnosis.

FAQs

• What should I check before choosing this harness?
  Confirm the vehicle year, K-jet application, existing wiring arrangement and part reference. Compare the connectors with those on the original loom.
• Does an intermittent fault prove the loom is defective?
  No. Test circuit continuity, supplies and earth connections, and inspect terminals before replacing parts.
• Can an existing loom be repaired instead?
  A localised defect may be repairable. Widespread insulation damage, corrosion or numerous unreliable joins can make replacement more appropriate.

These symptoms can have several causes. Inspect the battery connections, earth straps and individual circuits before attributing a fault to the harness.

Why Replacement Matters

Renewal may be appropriate where insulation has deteriorated extensively, conductors have fractured or earlier repairs have left unreliable connections. Replacing a confirmed faulty loom addresses the wiring itself rather than repeatedly changing connected components. OE Match focuses on Porsche replacement applications; matching the original reference and vehicle specification remains essential.

FAQs

Can a damaged connection resemble a component failure?
Yes. Poor terminal contact can interrupt an electrical supply or alter a signal, so the connected component may not be responsible.

Should a small damaged section be repaired instead?
A localised fault may be repairable, while extensive deterioration can make harness replacement more appropriate. Have the condition assessed before deciding.

What should be checked before installation?
Compare the original reference, model year, engine specification, connector arrangement and wiring route with the existing loom.
