14-pin plug connector with harness for engine loom. 
This 14-pin plug connector with harness is a high-quality OE Match replacement electrical connector used in the engine wiring loom of multiple Porsche models. It replicates the original factory connector in design, pin layout, and fitment, providing a reliable connection between the engine harness and vehicle electrical system.

Fits:
Porsche 911 - 1970 to 1989 
Porsche 911 turbo - 1975 to 1989
Porsche 914 -1970 to 1976
Porsche 924S - 1986 to1988
Porsche 928 - 1983 to 1995 
Porsche 944S2 - 1985 to 1991 
Porsche 964 - 1989 to 1994 
Porsche 968 - 1992 to 1995

The connector provides a central electrical interface between the engine wiring loom and the vehicle’s main electrical system. It ensures consistent signal and power transmission to critical engine components, sensors, and control systems.

Function:
•  Connects engine wiring loom to vehicle electrical system
•  Maintains reliable electrical continuity across multiple circuits
•  Prevents signal loss, voltage drop, and intermittent faults
•  Supports stable engine operation and diagnostics

Over time, original connectors can suffer from heat exposure, corrosion, brittle plastic, or wiring fatigue. This replacement restores proper electrical integrity within the engine loom, helping to prevent intermittent faults, sensor errors, and poor engine performance. It is ideal for engine rebuilds, wiring repairs, or full loom restorations where dependable OE-level quality is required.

A degraded or damaged engine loom connector can cause a wide range of electrical issues, from poor engine running to complete system failure. Replacing it with a quality OE Match connector restores electrical reliability, improves long-term durability, and helps protect the engine management system from unpredictable faults.

When to replace:
•  Cracked, brittle, or heat-damaged connector housing
•  Corrosion or looseness at pin terminals
•  Intermittent electrical faults or poor engine performance
•  During engine loom repair or restoration
•  When upgrading or refurbishing engine wiring

The air conditioner relay switches electrical power to the A/C system when requested by the climate control or air conditioning controls. A correctly working relay helps ensure the air conditioning system can engage and operate reliably.

Functions
• Replaces the air conditioner relay
• Helps control A/C system electrical switching
• Supports correct compressor or A/C circuit engagement
• Helps restore reliable air conditioning operation
• Suitable for fault diagnosis and A/C electrical repair
• OE Match replacement for Porsche climate control service

Why Replace This Part?
Air conditioner relays can fail due to age, heat, electrical load, corrosion, internal contact wear, or moisture exposure. A faulty relay may cause the A/C system to stop working, work intermittently, fail to engage, or show inconsistent cooling performance. Replacing the relay can help restore reliable electrical switching within the air conditioning system.

When to Replace This Part
•  Air conditioning does not switch on
•  A/C operation is intermittent
•  Compressor or A/C circuit is not receiving power
•  Climate control fault diagnosis points to relay failure
•  Existing relay is corroded, overheated, or damaged
•  A/C electrical repair or restoration is being carried out
•  Preventive replacement is required during climate system service.

Where it fits on the car
This relay fits within the vehicle electrical relay / fuse system for the air conditioning circuit. Location can vary depending on model and year.

Diagram Ref No 7

Depending on the model and relay position, 92861520301 is used for either the fanfare/horn circuit or the heated rear window / rear defroster circuit. Porsche parts cataloguing identifies the relay as the rear window heating relay on Porsche 928, 944 and 968 applications, while Porsche 964 electrical diagrams also list the same part number for the fanfare/horn relay position.

The relay allows the electrical system to supply the current required by the horn or heated rear window without routing the full operating current through the dashboard switch.

What This Product Does:

• Electrically switches a higher-current circuit using a lower-current control signal.
• Provides power to the relevant horn or rear-window-heating circuit.
• Helps protect switches and control wiring from carrying excessive electrical current.
• Allows reliable operation of the connected electrical component.
• Provides electrical isolation between the control circuit and load circuit.
• Replaces an original relay with burnt, worn or intermittent contacts.
• Helps restore factory electrical operation in classic Porsche models.

When used for rear window heating, the relay supplies electrical power to the heated rear glass when the system is activated. Porsche cataloguing specifically identifies 92861520301 as the rear-window-heating/defroster relay on several applications.

When used as the fanfare relay, the relay switches power to the horn circuit when the horn control is operated. The Porsche 964 central electrical diagram lists 92861520301 at relay position R23 as the fanfare relay.

Symptoms Of Wear Or Failure:
Because the same relay can perform different functions depending on the vehicle, symptoms vary according to where it is fitted.

Possible symptoms include:

• Horn failing to operate.
• Horn working only intermittently.
• Delayed horn operation.
• Horn operating only after repeated use of the switch.
• Rear window heater failing to operate.
• Rear window taking much longer than normal to clear.
• Heated rear window working intermittently.
• Rear window heating cutting in and out unexpectedly.
• Relay clicking without the connected circuit operating.
• No audible relay click when the relevant switch is operated.
• Electrical function returning temporarily after the relay is moved or tapped.
• Burnt or discoloured relay terminals.
• Corrosion on electrical contacts.
• Signs of overheating around the relay or socket.
• Intermittent operation that worsens as the relay heats up.

A failed relay is not the only possible cause of these symptoms. Fuses, wiring, switches, earth connections, horn units and rear window heating elements should also be checked during diagnosis.

Why Replacement Matters:
Electrical relays contain internal contacts that open and close every time the circuit is operated.

Over years of service, these contacts can become:

• Burnt.
• Pitted.
• Oxidised.
• Contaminated.
• Mechanically worn.

Age and repeated heating cycles can also weaken the internal coil or switching mechanism.

Once the relay becomes unreliable, electrical power may no longer reach the connected component consistently.

Replacing a defective relay helps restore:

• Reliable horn operation.
• Correct rear window heating where applicable.
• Consistent electrical switching.
• Proper current delivery.
• Reliable operation of the associated circuit.
• Factory-style electrical functionality.
