Hyundai Kia 12-Pin Headlight Wire Harness Connector – Male & Female OEM

This 12-pin headlight connector is designed for Hyundai and Kia vehicles with multi-function LED or adaptive headlight assemblies. The 12-pin configuration integrates low beam, high beam, DRL, turn signal, leveling motor, and AFS (Adaptive Front-lighting System) circuits in a single connector. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Key Specifications

Pin Function Overview

A 12-pin headlight connector on Hyundai/Kia platforms typically serves: low beam (2 pins), high beam (2 pins), DRL/position light (2 pins), turn signal (2 pins), headlight leveling motor (2 pins), and AFS/adaptive lighting control (2 pins). Verify your vehicle’s wiring diagram for exact pin assignments.

Why Headlight Connectors Fail

Multi-pin headlight connectors on Hyundai and Kia vehicles are exposed to road vibration, thermal cycling, and moisture from the headlight housing. Terminal oxidation or housing cracks cause intermittent headlight failures, AFS warning lights, or B-code fault codes. Replacing the connector restores full headlight circuit integrity.

Variant Guide

• Male – Bare male housing with terminals
• Male 15CM – Male connector with 15cm pre-wired leads
• Female – Bare female housing with terminals
• Female 15CM – Female connector with 15cm pre-wired leads

Installation Steps

1. Disconnect the vehicle battery
2. Remove the headlight assembly to access the harness connector
3. Release the locking tab and unplug the original 12-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, turn signal, AFS)
