OE Match alternator wiring loom for Porsche 901 / 911 models from 1969–73 equipped with Bosch alternators. This replacement harness serves the wiring connection between the alternator and voltage regulator.
Fits
- Porsche 911 1969-73
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The loom groups the electrical connections associated with the alternator and regulator. It is a wiring component, rather than a replacement alternator or voltage regulator, and is intended for repairs involving damaged or deteriorated charging-system wiring.
Functions
- Connects the Bosch alternator and regulator wiring.
- Groups the associated conductors into a harness.
- Provides a replacement for deteriorated wiring during electrical repairs or restoration.
Technical Details
- Part number: 90161203720.
- Brand: OE Match.
- Application: Bosch alternator wiring.
- Internal diagram description: wiring harness NR. 2 0, regulator/generator, Bosch.
Symptoms of Fault
- Charging that becomes intermittent or insufficient.
- Battery warning lamp illumination or flickering lights.
- Cracked, brittle or melted wire insulation.
- Corrosion at terminals or connectors.
- Electrical behaviour that changes when the wiring moves.
Why Replacement Matters
Renewal may be appropriate when conductors are damaged, insulation has deteriorated, connections have corroded or earlier repairs have left unreliable joins. Confirm the source of the fault first: battery condition, earth connections, alternator and regulator faults can produce similar symptoms. Replacing the loom will not correct a defective charging unit.
FAQs
- Is this the alternator itself?
No. The product is the wiring loom for a Bosch alternator application. - What should be checked before replacement?
Inspect the existing harness, terminals, battery connections and earth straps. Electrical testing should establish whether the wiring is responsible for the charging fault. - Does the model year alone confirm compatibility?
No. Compare the installed alternator, regulator connections and existing loom with the required application, particularly if the charging system has previously been changed. - Can the original wiring be repaired instead?
A localised defect may be repairable, while widespread insulation damage or corrosion can justify replacing the harness.

OEMatch Standard Alternator / Genarator — Fit, Function, Confidence
Standard output alternators convert mechanical energy into electrical power to run vehicle systems and maintain battery charge for Porsche models. Many owners search for genuine or OEM alternators; these are direct-fit alternatives designed to match the original form, fit and function.
Available Types
- Standard output alternators for road use
Understanding OEMatch Standard Alternator / Genarator
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original alternators. OE (Original Equipment) refers to parts matching original specifications for the alternators and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM alternators engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Alternators generate the electricity required to power ignition, lighting, infotainment and charging circuits. They must regulate voltage and deliver steady current under heat and vibration. Symptoms of reduced alternator performance include dimming lights, warning indicators, slow cranking or a failing battery; early detection helps prevent secondary electrical faults.
Benefits Include
- Restores consistent battery charging and voltage regulation
- Maintains correct operation of lights, ignition and accessories
- Prevents battery drain and related starting issues
Why Standard Alternator / Genarator Wear and Fail
- Worn bearings or brushes reducing mechanical and electrical efficiency
- Faulty voltage regulators causing under- or overcharging
- Corrosion or contamination of internal connections and cooling passages
The Importance of Replacing with OEMatch Standard Alternator / Genarator
A functioning alternator keeps your Porsche’s electrical system working and helps avoid a drained battery or roadside immobilisation. Replacing a weak or damaged alternator restores reliable charging and reduces the risk of further electrical damage to vehicle systems, supporting day-to-day drivability and longer-term component life.
Advantages
- Compatible replacements that restore charging function
- Designed to interface with Porsche electrical systems and mounting points
- Built from materials chosen for durability and balance
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
