6-Pin Waterproof Tail Light & Sensor Connector – Type A / B / C Female OEM

This 6-pin waterproof female connector is used in tail light assemblies and rear sensor harnesses. Available in three body configurations (Type A, B, C) to match different OEM tail light harness designs. Each type has the same 6-pin layout but different housing shapes and locking tab positions. Available bare or with 15cm pre-wired leads.

Key Specifications

Tail Light Connector Pin Functions

A 6-pin tail light connector typically serves: stop light (brake), turn signal, reverse light, tail/position light, ground, and a sensor or module signal circuit (e.g., rear parking sensor, light module communication). Verify your vehicle’s wiring diagram for exact pin assignments.

Why Tail Light Connectors Fail

Tail light connectors are exposed to road spray, moisture, vibration, and thermal cycling from the light assembly. Terminal corrosion or housing damage causes intermittent brake light failures, turn signal faults, reverse light malfunctions, or rear sensor errors. Replacing the connector restores full tail light circuit integrity.

Variant Guide

• Type A Female / A Female 15CM – Type A housing configuration
• Type B Female / B Female 15CM – Type B housing configuration
• Type C Female / C Female 15CM – Type C housing configuration

Compare the housing shape and locking tab position of your existing tail light connector with the variant images to select the correct type.

Installation Steps

1. Disconnect the vehicle battery
2. Remove the tail light assembly to access the harness connector
3. Release the locking tab and unplug the original 6-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the tail light and verify all functions (brake, turn, reverse, position)

Frequently Asked Questions

Q: How do I identify which type (A, B, or C) I need?
