This harness provides a complete OEM-style solution for converting North American MK8 vehicles to European-spec IQ tail lights. It goes beyond simple plug-and-play harnesses by integrating directly into the Central Electronics Control Module (CECM), unlocking the full functionality and behavior of true European IQ lighting systems.
Features
Direct CECM integration for full European IQ light functionality
Enables rear fog light operation and independent brake and turn signal channels
Supports advanced IQ tail light animations and sequencing (where applicable)
Approximately 90% pre-configured, requiring only a few key CECM connections
Built using OEM-grade connectors and pre-labeled wiring for clean installation
Factory-Level Functionality
This harness replicates the exact configuration used on European models equipped with IQ tail lights. It activates rear fog, independent left/right signal channels, and dynamic lighting effects, providing enhanced safety and the authentic Euro lighting experience.
Dataset Update Required
To enable all IQ light features and ensure error-free operation, a Dataset update to the CECM is required. This service can be performed by Antony from ACM Technik LLC and aligns your vehicle’s control module with European lighting data for proper communication and performance.
Fitment
Designed for North American MK8 vehicles upgrading to European-spec IQ tail lights
Works with both OEM IQ tail lights and aftermarket Euro-style IQ-compatible lights
Not suitable for basic plug-and-play conversions without CECM integration
Why Use This Harness
Plug-and-play kits can only partially mimic IQ tail light behavior. This harness delivers full OEM-level integration, enabling every channel and light animation exactly as intended on European vehicles. It’s the most complete and accurate IQ lighting retrofit solution available.
Installation Notes
Not plug-and-play — requires CECM wiring connections

Reviews
Harness works perfectly, combined with the datasets and it’s like the car came with the euro taillights from factory. This is the only OEM grade solution as the car will even show it has the euro taillights installed on the vehicle preview screen once it has the datasets installed.
