What This Product Does
The harness groups the wiring serving the front lighting and horn connections into an organised assembly. It is intended for repairs to this section of the vehicle's electrical installation, rather than replacement of the complete vehicle loom.
Functions
- Connects the fuse box to the headlamp wiring.
- Provides wiring for the horn circuit.
- Groups associated conductors within the front luggage compartment.
Technical Details
- Part reference: 91161200301.
- Brand: OE Match.
- Installation area: front luggage compartment.
Symptoms of Fault
- Headlamps operating intermittently or flickering.
- Loss of operation in an affected circuit.
- Repeated fuse failure associated with damaged wiring.
- Cracked insulation, rubbed-through covering or exposed conductors.
- Corroded terminals or loose electrical connections.
- Faults that change when the loom moves.
Why Replacement Matters
Renewal may be appropriate when inspection identifies damaged insulation, broken conductors, heat deterioration or unsuitable previous alterations. Establish the cause before replacing the loom: bulbs, fuses, earth connections and adjoining terminals can produce similar symptoms. Supporting connections should also be inspected so that an unresolved fault does not remain after fitting.
FAQs
Can a wiring fault be intermittent?
Yes. Movement or temperature changes can interrupt contact at a damaged conductor or connection.
What should be checked before replacement?
Inspect the routing, insulation, terminals, earth points and fuse condition. Continuity and voltage-drop testing can help locate the affected section.
Is this a complete vehicle wiring harness?
No. The supplied information identifies the front section serving the fuse box, headlamps and horn.

This harness assembly is designed as a direct-fit replacement for the factory wiring loom that serves the driver’s-side door switch and window-regulator system on Porsche 911 models. It reconnects the control switch, window motor/regulator and associated connectors with OEM-style routing, connectors and insulation for restored function and reliability.
Fits:
Porsche 911 - 1969 to 1989

• Function: The harness carries the electrical connections for the power-window mechanism and associated door controls (switches, regulators) in the driver-side door module. Accurate harness fitment ensures consistent switch response, smooth window movement and prevents wiring stress or connector failure.
• Application: Driver’s-door wiring harness for power window and switch functions
• Over time, door harnesses are subject to moisture, wear from repeated window operation, hinge motion and vibration. Insulation may crack, connectors loosen or wires may become corroded - resulting in intermittent switch behaviour, non-functional windows or electrical faults. Replacing with a correct-spec harness restores reliable window/switch operation, prevents costly intermittent issues and supports long-term electrical integrity.
