Ensure full CAN-bus integration and safe electrical operation when towing with this Genuine OEM Vauxhall / Opel Trailer Towbar Control Module (Part Number: 13505411). This original factory ECU unit manages trailer lighting signals, brake/indicator output, and communicates directly with your vehicle's Body Control Module (BCM).
Aftermarket trailer relay bypass kits often trigger dash error warnings, compromise vehicle Trailer Stability Assist (TSA) functions, or overload the factory wiring harness. Fitting an authentic General Motors towing control module ensures proper integration with vehicle safety systems, automatic rear parking sensor deactivation when hitched, and reliable signal handling.
- Factory CAN-Bus Integration: Seamlessly manages tail lights, brake lights, indicators, and fog lamps on attached trailers or caravans.
- Vehicle System Coordination: Enables factory Trailer Stability Assist (TSA) and automatically disables rear parking sensors when a trailer plug is connected.
- Direct Plug-and-Play Installation: Plugs directly into the factory rear electrical center (REC) / pre-wired towbar harness connectors.
- Genuine GM Electronic Reliability: Built to stringent OEM standards to protect delicate vehicle electronics against circuit overload and voltage spikes.
