When you hook up a trailer, you'll typically encounter a connector on your Ram that needs to mate with a corresponding connector on the trailer. The diagram will show you the pinout of this connector. For instance, a common setup for 1999 Dodge Rams includes a 4-pin or 7-pin connector. The 4-pin is generally for basic lighting functions:
- White Wire Ground

- Yellow Wire Left Turn Signal/Brake Light
- Green Wire Right Turn Signal/Brake Light
A 7-pin connector offers more functionality, including:
- Blue Wire Electric Trailer Brakes

- Red Wire Auxiliary Function (often for reverse lights or other accessories)
- And the four basic lighting functions mentioned above.
Having the correct 1999 Dodge Ram trailer wiring diagram ensures you can troubleshoot any issues that arise. If a light isn't working, you can use the diagram to trace the wire and check for loose connections, broken wires, or blown fuses at either the truck or the trailer end.
