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.

  FAQs

• Does poor charging prove that the harness needs replacing? No. Check the battery, alternator, regulator, earth connections and wiring, then replace the component shown to be faulty.
• Should I repair the existing loom or replace it? An isolated fault may be repairable. Widespread insulation damage, corroded connections or numerous unsuitable joins can justify replacing the harness.
