2024-2025 GM vehicles with Factory Integrated Trailer Brake Controllers may encounter a compatibility issue when towing trailers with electric brakes or Electric Over Hydraulic Brake (EOHB) systems.

This issue can result in a fault message, indicating disabled trailer brakes or a service requirement for the trailer brake wiring, appearing on the in-dash display

We have developed a module that will eliminate this issue.

Note: Installing the Module to your trailer will not effect other Brand of tow vehicles.

2-Wire Module Easy to install, simply hardwires in between your Brake Controller Wire “BLUE” wire connection. Wires are labeled to ensure proper installation. One wire has to be pointed towards the tow vehicle and the other is wired in the direction of your trailer.
