Single cable for additional brake light, Black
The Genuine Porsche Third Brake Light Wire is an original equipment electrical connection component designed for Porsche 911 (993) Coupé models equipped with the centre high-mounted stop lamp (Option Code: M602). This connecting wire, identified by its black connector, forms part of the third brake light wiring assembly, providing an electrical connection between the vehicle's brake light circuit and the centrally mounted rear stop lamp.

Fits:
Coupe models only, with M602 - Centre high-mounted stop lamp
Porsche 993 (911) Carrera 2 (1994 - 1998)
Porsche 993 (911) Carrera 4 (1995 - 1998)
Porsche 993 (911) RS (1996 - 1997)
Porsche 993 (911) Turbo (1995 - 1998)

Manufactured to Porsche's original specifications, this genuine replacement wire provides precise fitment and reliable electrical connectivity, helping maintain the correct operation of the high-mounted brake light.

Ideal for replacing damaged, corroded or faulty original wiring during brake light repairs, electrical maintenance or classic Porsche restoration.

What Is This Part?
This is a single wiring lead within the third brake light electrical connection. It connects into the lamp circuit rather than forming a complete vehicle wiring harness. The additional brake light assembly uses separate electrical leads, so identifying the correct lead matters when repairing a damaged connection. This component is relevant when inspection shows that the individual wire or its terminal needs replacement.

What Does This Part Do?

• Provides an electrical connection: Forms part of the circuit serving the additional brake light.
• Links the lamp to its wiring: Provides the individual lead used at the brake light connection.
• Allows a localised repair: Replaces the affected lead where the surrounding wiring remains serviceable.

Why Replace This Part?
Ageing insulation, broken strands or deterioration at a terminal can interrupt the electrical connection to the third brake light. Damage may also occur if wiring is pulled, trapped or disturbed during work around the lamp. Replace the lead if inspection confirms damage that prevents a sound connection.

A non-working or intermittent brake light does not by itself identify this wire as the cause. Check the lamp, electrical supply and associated connections before deciding which component needs renewal.

When to Replace This Part?

• Damaged insulation: Cracking, cuts or chafing expose the conductor.
• Broken wiring: The lead is severed, stretched or has damaged strands.
• Deteriorated terminal: Corrosion or physical damage prevents a secure electrical connection.
• Confirmed intermittent connection: Testing identifies a fault within this lead rather than elsewhere in the circuit.
• Damage found during lamp work: Inspection during removal or refitting reveals that the lead cannot be reused.

Where Is This Part Fitted?
Location: At the electrical connection for the additional third brake light on the applicable Porsche 993 Coupe, as part of the lamp wiring.
