BRAKERITE OEM BRAKE CONTROL ADAPT.

The purpose of this device is to allow the signals sent by your trucks brake controller to properly communicate with your Titan Brake Rite system. If your vehicle requires this Converter Box, and you do not use it, your trucks brake controller will not be able to work in harmony with your trailers brake system. The simply reason why this is needed, is because Factory Installed In Dash Brake Controllers are designed for use with Electric Brakes only, not Electric Over Hydraulic.
