Trailer Brake Wiring Diagram 2007 Ram 3500. I have been having the issue where my trailer brake controller will flash the SC and on the dash say "check trailer brake wiring" and "trailer brake disconnected" and the worst part about it is everything about it is random. some days it will. Dodge Wiring Diagrams / Schematics - YouTube. you have to get under truck look for access hole at backing plate you need brake adjusting tool to turn adjusting star wheel until drum brakes away from brake drum so you can.
I had all connectors which allowed me to install it. Typical trailer wiring: Green - right rear turn signal Yellow - left rear turn signal Brown - Tail lights/marker lights White - ground. For wiring diagrams and such, grab the factory service manual from here.
Or where can I get one?
Hope this will help you to set you trailer brake on your RAM truck.
