14-Pin Xenon / LED Front Headlight Wire Harness Connector – Male & Female OEM

Modern xenon (HID) and LED headlight assemblies are significantly more complex than halogen units – they contain ballasts, LED drivers, AFS (Adaptive Front-lighting System) motors, leveling actuators, and CAN bus nodes, all requiring a high-density connector to interface with the vehicle harness. This 14-pin connector serves the front headlight assembly harness for xenon and LED headlight systems, integrating all headlight circuits through a single high-density connection. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Key Specifications

Why 14-Pin Headlight Connectors Are Used

The shift from halogen to xenon and LED headlights dramatically increased the circuit count in the headlight harness. A halogen headlight needs only 3–4 circuits (low beam, high beam, position, ground). A xenon headlight adds a ballast power circuit, ballast control signal, and igniter circuit. An LED headlight with AFS adds LED driver power, LED driver CAN bus, AFS motor control (2 circuits), leveling motor, and a headlight module LIN bus node. The 14-pin connector accommodates all of these circuits in a single connection, eliminating the need for multiple smaller connectors in the headlight housing.

Variant Guide

• Male / Male 15CM – Plug-side connector for the headlight module
• Female / Female 15CM – Socket-side connector for the vehicle harness

Installation Steps

1. Disconnect the vehicle battery
2. Remove the front headlight assembly to access the harness connector
3. Release the locking tab and unplug the original 14-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the headlight and verify all functions: low/high beam, DRL, AFS, leveling
6. Perform AFS headlight calibration if required using a compatible scan tool

Frequently Asked Questions

Q: What fault codes indicate a failed 14-pin headlight connector?
A: Common codes include B-codes for headlight circuit faults, xenon ballast communication errors, AFS module faults, LED driver communication errors, and headlight leveling motor circuit faults on compatible diagnostic systems.

Q: Is AFS calibration required after replacing the connector?
A: If the headlight module was disconnected, an AFS headlight calibration (headlight aim calibration) is recommended using a compatible scan tool.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
