Utilize this module to eliminate error codes from and ensure proper functionality of your fancy new truck tailgate light. Simply plug the module into the 4-pin trailer plug, plug into the tailgate light, tap to power, and that’s it! Tuck it away and forget about it. Guaranteed to work on any truck with trailer detection, blindspot monitoring, factory LED taillights, and more. Of course we think it’d be best to use it with one of our Sequential Truck Tailgate Lights, but the module will work with any third party light as well. This is the end-all solution for your truck tailgate light!
