OE Match engine wiring loom for Porsche 911 K-jet applications from 1974–75. Manufactured in Canada for replacement or restoration work involving the engine wiring.

Fits

• Porsche 911 1974-75
  
  

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The loom groups the engine's electrical connections into an organised assembly. It carries electrical supplies and signals between connected components, providing the wiring paths needed for their operation. This is a wiring harness, not an alternator or generator.

Functions

• Connects engine electrical components through a grouped wiring assembly.
• Carries power and electrical signals through the connected circuits.
• Replaces an existing engine loom affected by deterioration or unsuitable previous repairs.
  
  

Technical Details

• Brand: OE Match.
• Part reference: 91161201731.
• Application type: K-jet engine wiring.
• Country of manufacture: Canada.
  
  

Symptoms of Fault

• Starting or running faults that occur intermittently.
• Electrical operation changing when wiring is moved.
• Cracked, hardened or melted insulation around the engine.
• Corroded terminals or damaged connector housings.
• Voltage loss across a damaged wire or connection.
• Repeated fuse failures requiring investigation.
  
  

These observations can also have other causes. Inspect the wiring and test the affected circuit before deciding that the harness needs 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.

Engine Wiring Harness.

Porsche 911 Engine Wiring Harness for 1972–1973 911 models. Replaces the full engine electrical loom, connecting alternator, ignition, and sensors. Ensures reliable current flow.

Fits:

• Porsche 911 1972-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  
  

Diagram Ref No 9

What This Product Does:

• It connects the engine’s electrical components — alternator, ignition, sensors, and other engine peripherals — back to the fuse panel / engine bay wiring.
  
  

Symptoms Of Failure / Damage:

• No or intermittent charging (alternator not powering battery)
  
• Ignition / spark issues, misfires, dead cylinders
  
• Shorts, blown fuses in engine circuits
• Corroded / broken connectors, brittle insulation, oil damage leading to open circuits
• Erratic sensor readings or no connection to sensors
  
  

Why Replacement Matters:

• Restores electrical integrity in the engine bay — correct connections, reliable voltage paths
• Prevents electrical gremlins, such as random faults, shorts, or voltage drops
• A new harness with fresh connectors, grommets, and insulation resists heat, oil, vibration better than aged wiring

OE Match engine wiring harness for the Porsche 911 SC 3.0L, covering the 1982–83 application. 

Fits

Porsche 911 1982-83

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The loom groups the engine's electrical wiring, providing connections through which the associated components receive power or transmit signals. It is a wiring assembly, not an alternator, voltage regulator or ignition unit.

Functions

• Connects the engine's electrical circuits.
• Carries electrical supplies and signals between connected components.
• Keeps related wiring together within an engine harness assembly.
  
  

Technical Details

• Brand: OE Match.
• Part reference: 91161201604.
• Application: Porsche 911 SC 3.0L, 1982–83.
• Internal diagram description: engine wiring harness; SC application, with an 82-onwards note.
  
  

Symptoms of Fault

• Electrical operation that changes when the wiring moves.
• Cracked, hardened or melted insulation around the engine.
• Corroded terminals or damaged connector housings.
• Starting or charging problems associated with excessive circuit resistance.
• Repeated fuse failures or intermittent engine electrical faults.
  
  

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.

Generator Wire Lead Rubber Boot.

The OE MATCH Generator Wire Lead Rubber Boot is a replacement protective cover designed for the generator electrical connections on classic Porsche 356 and 912 models. This rubber boot helps insulate and protect the generator wire terminals from moisture, dirt, oil contamination and accidental electrical contact.
Sold Each.
x Required Per Car.

Fits:

• Porsche 356 1950-65
• Porsche 912 1965-69

Diagram Ref No 4

Designed to provide an OE-style fit and appearance, it is ideal for routine maintenance, electrical system repairs and classic Porsche restoration projects.

What This Product Does:

• The generator wire lead rubber boot covers the electrical terminal connections on the generator, helping protect them from environmental exposure and reducing the risk of accidental short circuits.
• It also helps maintain the original appearance of the engine bay while providing an additional layer of protection against dirt, moisture and everyday engine vibration.

Symptoms Of Wear Or Failure:
Over time, exposure to engine heat, oil and age can cause the original rubber boots to deteriorate. Common signs include:

• Cracked or split rubber: Age-related deterioration leaves electrical terminals exposed.
• Hard or brittle material: Loss of flexibility prevents the boot from fitting securely.
• Loose or missing boots: Electrical connections become vulnerable to contamination and accidental contact.
• Oil and dirt contamination: Damaged protective boots allow contaminants to accumulate around the generator terminals.
• Visible electrical corrosion: Moisture exposure may contribute to corrosion around terminal connections.

Why Replacement Matters:

• Replacing worn or damaged generator wire lead rubber boots is a simple but important step in maintaining the reliability and safety of your classic Porsche's electrical system.
• A correctly fitted replacement boot helps protect exposed generator terminals, reduces the risk of accidental short circuits and limits contamination that could contribute to poor electrical connections.
• Replacement also helps preserve the original engine bay appearance, making it particularly beneficial during restoration and preventative maintenance.
