Understanding Your 2004 Dodge Ram 1500 7 Pin Trailer Wiring Diagram
The 7-pin trailer connector on your 2004 Dodge Ram 1500 is designed to provide a comprehensive set of electrical connections for a wide variety of trailer types. It's a standardized system, meaning that a properly wired trailer will function correctly with any vehicle equipped with a standard 7-pin receptacle.
