Diagram ref no 2

Number 996-631-436-02 replaces earlier wiring harness versions 996-631-436-00 and 996-631-436-01.

It carries electrical signals to/from the rear lights (tail, brake, number plate, indicators / third brake light etc.). Proper wiring is essential for safety (brake lights, indicators) and legal compliance (rear lamps and number plate lights).

When to Replace:
•  If lights are intermittent, flickering, or failing (one or more rear lights stop working), suspect a wiring issue
• If there's visible damage: frayed wires, broken connectors, corrosion, melted insulation, or water ingress
• After accident damage to rear panels / light assemblies where the harness may have been crushed, stretched, or damaged
•  When doing restoration or refurbishment of the rear light area to bring it back to OEM condition
•  If earlier harness versions (-00 or -01) are failing, upgrading to the newer -02 version ensures better reliability.
