Understanding Ford Trailer Plug Wiring Diagrams for a Safer Trip

Travelling around with a trailer can be exciting and complicated at the same time. From the electrical wiring to having the right kind of hitch, there are many items to think of before setting off on your journey. But the wiring is an especially important factor to consider when hauling large loads in a trailer.

The wiring diagrams of Ford’s trailer plugs can provide you with the guidance you need to ensure that all of your equipment functions correctly and safely. Understanding what each color and type of wire represents and looks like will help you diagnose any issues or potentially dangerous malfunctions. Let's dive into the Ford trailer plug wiring diagram, as well as when and where to use it.

Identifying Your Ford's Trailer Plug Type

When it comes to Ford trailers, determining the type of connector plug the vehicle is equipped with should be the first step. Most Ford vehicles come with either a 6-pin or 7-pin connector at the back of the vehicle. It’s important to note that knowing how to use the correct plug is essential in proper wiring, otherwise you could place yourself and/or others in harm’s way.

If you know the specific type of Ford trailer plug you have, finding the corresponding wiring diagram is much easier. If you don't know your plug type, you’ll first need to determine which one you have:

A 6-pin connector typically has one extra brown wire than the 7-pin connectors.

The 7-pin connector, also called the “Round 7”, is designed for larger trailer loads and thus has more wires.

For either type, you’ll want to look for the small plastic cover piece or “cap” on the back of your Ford, which will allow you to see the pins.

Understanding the Ford Trailer Plug Wiring Diagram

Let's take a closer look at what each colored wire represents in the trailer plug wiring and how they are used:

Colour	Use
White	Ground Wire
Brown	Tail Lights
Yellow	Left Turn Signal & Brake Light
Green	Right Turn Signal & Brake Light
Red	Stop & Reverse Lights
Blue	Backup Lights
Black	Electric Brake

Using the Right Wiring Connections

It's always important to make sure you're using the right wiring connections for your Ford trailer plug wiring diagram. The most common type of connection is a four-wire flat plug. This type of plug is designed to connect one of the four wires in the car to the same type of wire in the trailer.

You may also need to make connections between two different types of wiring. For example, the yellow wire may need to be connected to both the left and right turn signal & brake light lines. In this case, an adapter is needed to bridge the two lines. Another option is a connecting block. This allows for conversion from one type of plug to another.

Following the Safety Guidelines

Trailer wiring is a delicate process that must be done according to the manufacturer guidelines and safety standards. In order to ensure your trailer is wired correctly and safely, it's important to read up on Ford's wiring diagrams and use specialized tools such as testers and voltage meters.

As mentioned previously, it's always beneficial to find the Ford trailer plug that corresponds to your vehicle and follow the safety tips:

Use approved components and materials

Check for any loose connections

Install the correct wiring for the correct voltage level

Ensure any wiring is effectively supported and protected from abrasion

Keep wiring away from any sources of heat

Conclusion

Ford trailer plug wiring diagrams can be invaluable when it comes to ensuring you have the correct wiring for your trailer and vehicle. Taking the time to refer to the wiring diagram and making the appropriate connections can be critical for the safety of both your vehicle and the load you are hauling. Make sure you understand your Ford's trailer plug type, use the right wiring connections and follow the safety guidelines to always stay safe on the road.
