A trailer wiring diagram is a handy tool that will help you connect your trailer lights to your Ram 1500’s electrical system. This journal article will provide you with a detailed 2013 Ram 1500 trailer wiring diagram, along with some frequently asked questions about trailer wiring.
Trailer Wiring Diagram
The following diagram shows the standard 7-way trailer wiring diagram for a 2013 Ram 1500. This diagram is based on the standard wiring setup for most trailers in the United States. If your trailer has a different wiring setup, you may need to consult your trailer manufacturer’s wiring diagram.
| Pin | Wire Color | Function |
|---|---|---|
| 1 | White | Ground |
| 2 | Blue | Electric Brakes |
| 3 | Green | Tail/Marker Lights |
| 4 | Red | Left Turn/Brake Lights |
| 5 | Brown | Right Turn/Brake Lights |
| 6 | Yellow | Reverse Lights |
| 7 | Black | 12V Battery Charge |
The trailer wiring diagram above shows the color coding for each wire and its corresponding function. The diagram is read from left to right, with the ground wire (white) on the left and the battery charge wire (black) on the right.
Pin 1 – White Wire (Ground)
The white wire provides the ground connection for the trailer’s electrical system. This wire should be connected directly to the trailer’s frame using a grounding screw or other appropriate means.
It is important that the ground connection be secure and free of any corrosion or other damage. A poor ground connection can cause problems with the trailer’s electrical system, including dim or non-functioning lights.
Pin 2 – Blue Wire (Electric Brakes)
The blue wire provides the signal for the trailer’s electric brakes. If your trailer is equipped with electric brakes, this wire must be connected to the brake controller in your Ram 1500’s cab.
The electric brake controller is a device that provides power to the trailer’s brakes based on the amount of pressure you apply to the brake pedal in your Ram 1500. This helps to ensure that the trailer’s brakes are applied smoothly and evenly, providing maximum stopping power.
Pin 3 – Green Wire (Tail/Marker Lights)
The green wire provides power to the trailer’s tail lights and marker lights. These lights are used to provide visibility for the trailer when it is being towed.
It is important that these lights be working properly, especially at night or in low light conditions. If your trailer’s tail and marker lights are not functioning properly, you may be at risk of a collision.
Pin 4 – Red Wire (Left Turn/Brake Lights)
The red wire provides power to the trailer’s left turn signal and brake lights. When you activate the left turn signal or apply the brakes in your Ram 1500, this wire sends a signal to the trailer to activate the corresponding lights.
Pin 5 – Brown Wire (Right Turn/Brake Lights)
The brown wire provides power to the trailer’s right turn signal and brake lights. When you activate the right turn signal or apply the brakes in your Ram 1500, this wire sends a signal to the trailer to activate the corresponding lights.
Pin 6 – Yellow Wire (Reverse Lights)
The yellow wire provides power to the trailer’s reverse lights. When you put your Ram 1500 in reverse, this wire sends a signal to the trailer to activate the reverse lights.
The reverse lights are an important safety feature that help to indicate to other drivers that you are backing up.
Pin 7 – Black Wire (12V Battery Charge)
The black wire provides power to the trailer’s battery, which is used to power any accessories or electrical equipment on the trailer. This wire is typically used to maintain the battery’s charge while the trailer is being towed.
If you have a trailer that requires power for accessories or electrical equipment, you will need to connect this wire to the appropriate circuit in your Ram 1500’s electrical system.
