Volkswagen Touran 6-Pin Wire Harness Connector – OEM 1J0973726 / 1J0 973 726

The OEM 1J0973726 is a 6-pin automotive connector used across Volkswagen PQ25/PQ35 platform vehicles including the Touran, Golf IV, Bora, and Passat. This connector appears in body control, HVAC, door module, and instrument cluster wiring harnesses. Available in Male/Female and with or without 15cm pre-wired leads.

Key Specifications

Why This Connector Fails

VW PQ-platform connectors in door modules and BCM circuits are prone to terminal oxidation and housing stress cracks from repeated door cycling and temperature swings. Symptoms include intermittent central locking failures, window regulator faults, interior lighting issues, or U-code CAN bus errors. Replacing the connector restores clean contact resistance and eliminates ghost faults.

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. Locate the 1J0973726 connector in the door module, BCM, or HVAC harness
3. Press the locking tab and unplug the original connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reconnect battery and clear fault codes with a VAG-compatible scanner
