The 2013 Ford F-150 is a rugged and powerful pickup truck that’s designed to handle just about anything you throw at it. Whether you’re hauling equipment or towing an RV, having a reliable trailer wiring system is essential to ensuring that your vehicle and trailer stay connected and safe on the road.
What is trailer wiring and why is it important?
Trailer wiring is a system that allows your vehicle to communicate with your trailer’s electrical system. This allows the trailer to receive power from the vehicle’s battery, as well as use the vehicle’s brake and turn signal lights. Proper trailer wiring is important because it ensures that your trailer operates safely and legally on the road, while also preventing damage to your vehicle’s electrical system.
How does trailer wiring work?
Trailer wiring typically includes a 4-way flat or 7-way round connector that attaches to your vehicle’s hitch. The connector then runs to your trailer’s lighting and brake system. The specific wiring diagram for your vehicle will depend on the type of connector that you’re using and the specific make and model of your vehicle.
What is a 4-way flat connector?
A 4-way flat connector is an older style of trailer wiring connector that has four pins. These pins are used to communicate between the vehicle and the trailer’s tail lights, brake lights, and turn signals. This style of connector is commonly used on small trailers, such as utility trailers and boat trailers.
What is a 7-way round connector?
A 7-way round connector is a newer style of trailer wiring connector that has seven pins. These pins are used to communicate between the vehicle and the trailer’s tail lights, brake lights, turn signals, and electric brakes. This style of connector is commonly used on larger trailers, such as RVs and horse trailers.

How to install trailer wiring on a 2013 Ford F-150
If your F-150 does not come with factory-installed trailer wiring, you can install an aftermarket wiring kit to get your vehicle ready for towing. Here’s a step-by-step guide to installing trailer wiring on your 2013 Ford F-150:
Step 1: Gather the necessary tools and equipment
Before you begin, you’ll need the following tools and equipment:
- A trailer wiring kit
- A set of wire cutters and strippers
- A crimping tool
- A socket set
- An electric drill and drill bits
Step 2: Remove the tail lights
To access the wiring for your F-150’s tail lights, you’ll need to remove them from the vehicle. Use your socket set to remove the screws holding the tail lights in place, then gently pull the lights away from the vehicle.
Step 3: Locate the wiring harness
The wiring harness for your F-150’s tail lights should be located behind the tail lights. Use your wire cutters to carefully cut away the protective sheathing from the harness, exposing the wires inside.
Step 4: Install the trailer wiring harness
Connect the trailer wiring harness to the appropriate wires in the F-150’s wiring harness, following the diagram provided by the manufacturer. Use your crimping tool to secure the connections, then wrap each connection with electrical tape to protect it from moisture and debris.
Step 5: Test the wiring
Before re-installing the tail lights, plug in your trailer wiring harness and test the lights to ensure that they’re functioning properly. This will help you avoid any potential issues when you’re on the road.
Step 6: Re-install the tail lights
Once you’ve confirmed that the trailer wiring is working correctly, re-install the tail lights on your F-150. Use your socket set to tighten the screws that hold the tail lights in place, then use zip ties to secure any loose wiring to the vehicle’s frame or other secure points.
Conclusion
Proper trailer wiring is essential to towing safely and legally with your 2013 Ford F-150. Whether you’re using a 4-way flat or 7-way round connector, make sure that your wiring is installed correctly and that all lights and brakes are functioning properly before hitting the road. If you’re not comfortable installing trailer wiring yourself, contact a certified mechanic or trailer installation specialist to assist you.
