If you own a 2006 Dodge Ram and need to tow a trailer, you will need to connect your trailer’s electrical system to your truck’s electrical system using a trailer plug. The trailer plug wiring diagram can be confusing and overwhelming, but this article will guide you through the process step by step. We will cover everything you need to know, including what tools you will need, how to identify the wires, and how to connect them. So, let’s get started!
What is a Trailer Plug Wiring Diagram?
A trailer plug wiring diagram is a schematic that shows how the wires in the trailer plug are connected to the corresponding wires in the truck’s electrical system. It is important to use the correct wiring diagram for your specific make and model of truck and trailer to ensure that the electrical connection is safe and secure.
Why Do You Need a Trailer Plug Wiring Diagram?
If you are planning to tow a trailer, you will need to connect the trailer’s electrical system to your truck’s electrical system. Without a trailer plug wiring diagram, it can be difficult to know which wires to connect and where to connect them. Using the wrong wiring diagram can result in electrical shorts, blown fuses, and even a fire.
Where Can You Find a Trailer Plug Wiring Diagram?
You can find a trailer plug wiring diagram in your truck’s owner’s manual, at a dealership or auto parts store, or online. It is important to use the correct wiring diagram for your specific make and model of truck and trailer.

The wires in the truck’s electrical system are as follows:
| Wire Color | Function |
|---|---|
| White | Ground |
| Brown/Red | Right Turn Signal |
| Green/Red | Left Turn Signal |
| Black/Orange | Battery Charging |
| Blue/White | Electric Brake |
| Violet/Black | Backup Lamps |
| Red/Black | Auxiliary Power |
| Gray/Black | Right Trailer Brake Output |
Tools You Will Need
Before you start connecting wires, you will need a few tools:
- Wire Strippers
- Wire Crimpers
- Butt Connectors
- Heat Shrink Tubing
- Electrical Tape
- Multimeter
Connecting the Wires
Ground Connection
The first thing you need to do is connect the ground wire. The ground wire is always the white wire. Connect the white wire from the trailer plug to the white wire in the truck’s electrical system. Use a butt connector to join the two wires.
Tail Light Connection
Next, connect the brown wire from the trailer plug to the brown/red wire in the truck’s electrical system. Use a butt connector to join the two wires.
Left Turn Signal Connection
Connect the yellow wire from the trailer plug to the green/red wire in the truck’s electrical system. Use a butt connector to join the two wires.
Right Turn Signal Connection
Connect the green wire from the trailer plug to the brown/red wire in the truck’s electrical system. Use a butt connector to join the two wires.
Electric Brake Connection
Connect the blue wire from the trailer plug to the blue/white wire in the truck’s electrical system. Use a butt connector to join the two wires.
Auxiliary Power Connection
Connect the red wire from the trailer plug to the red/black wire in the truck’s electrical system. Use a butt connector to join the two wires. This wire is for supplying power to the trailer’s accessories, such as interior lights or electric brakes.
Battery Charging Connection
Connect the black wire from the trailer plug to the black/orange wire in the truck’s electrical system. Use a butt connector to join the two wires. This wire charges the trailer’s battery while it is being towed.
FAQ
What if the Colors Don’t Match?
If the colors of the wires in the trailer plug and the truck’s electrical system don’t match, you will need to use a multimeter to identify which wire is which. Use the continuity setting on the multimeter to test each wire and match it to the corresponding wire in the wiring diagram.
What if I Have a Different Make and Model of Truck or Trailer?
If you have a different make and model of truck or trailer, you will need to find the correct wiring diagram for your specific vehicle. The process of connecting the wires will be similar, but the wire colors and functions may be different.
Can I Connect Multiple Trailers to my Truck?
Yes, you can connect multiple trailers to your truck, but you will need to use a different wiring harness for each trailer. Each trailer will need its own trailer plug and wiring diagram.
What if I Don’t Feel Comfortable Doing the Wiring Myself?
If you don’t feel comfortable doing the wiring yourself, you can take your truck and trailer to a professional mechanic or auto body shop. They will be able to do the wiring for you and ensure that it is safe and secure.
What if I Have a Problem with My Trailer’s Electrical System?
If you have a problem with your trailer’s electrical system, you should first check to make sure that the wiring is connected correctly. If the wiring is correct, you may have a blown fuse or a problem with the trailer’s electrical components. You can take your trailer to a professional mechanic or auto body shop to have it diagnosed and repaired.
Conclusion
Connecting your trailer’s electrical system to your truck’s electrical system may seem overwhelming, but with the right tools and a good wiring diagram, it can be done safely and easily. Remember to use the correct wiring diagram for your specific make and model of truck and trailer, and always double-check your connections before towing. If you have any questions or concerns, don’t hesitate to consult a professional mechanic or auto body shop.
