If you are looking for a reliable and efficient wiring diagram for your 2019 F350 trailer plug, then you have come to the right place. This article will provide you with everything you need to know about wiring your trailer plug, including the different types of plugs available, the wiring configurations, and step-by-step instructions on how to wire your trailer plug.
Types of Trailer Plugs
There are three main types of trailer plugs available for the 2019 F350: the 7-pin, 6-pin, and 4-pin connectors. The 7-pin connector is the most common and it provides the most functionality, while the 6-pin and 4-pin connectors are more basic and provide fewer functions.
The 7-Pin Connector
The 7-pin trailer plug is the most common type of connector used on trailers. It provides power to all the trailer’s lights, brakes, and other auxiliary functions. The 7-pin connector has seven pins, each of which serves a different function.
Pin 1 – Left Turn Signal and Brake Light
Pin 2 – Auxiliary and Reverse Lights
Pin 3 – Ground
Pin 4 – Right Turn Signal and Brake Light
Pin 5 – Electric Brakes
Pin 6 – 12 Volt Battery Charge
Pin 7 – Backup Lights
The 6-Pin Connector
The 6-pin trailer plug is similar to the 7-pin connector, but it has one less pin. It is typically used on trailers that do not require electric brakes. The 6-pin connector has six pins, each of which serves a different function.
Pin 1 – Left Turn Signal and Brake Light
Pin 2 – Auxiliary and Reverse Lights
Pin 3 – Ground
Pin 4 – Right Turn Signal and Brake Light
Pin 5 – Electric Brakes (if present)
Pin 6 – 12 Volt Battery Charge
The 4-Pin Connector
The 4-pin trailer plug is the most basic type of connector used on trailers. It is typically used on small trailers that do not require electric brakes. The 4-pin connector has four pins, each of which serves a different function.
Pin 1 – Left Turn Signal and Brake Light
Pin 2 – Right Turn Signal and Brake Light
Pin 3 – Tail and Marker Lights
Pin 4 – Ground
Wiring Configurations
The wiring configuration for your trailer plug will depend on the type of plug you are using and the functions you want to provide. Below are some common wiring configurations for each type of trailer plug.
7-Pin Connector Wiring Configuration
| Pin | Function | Wire Color |
|---|---|---|
| 1 | Left Turn Signal and Brake Light | Brown |
| 2 | Auxiliary and Reverse Lights | Yellow |
| 3 | Ground | White |
| 4 | Right Turn Signal and Brake Light | Green |
| 5 | Electric Brakes | Blue |
| 6 | 12 Volt Battery Charge | Red |
| 7 | Backup Lights | Black |
When wiring your 7-pin connector, make sure to follow the wiring configuration carefully. Incorrect wiring can cause your trailer’s lights not to function properly, or even cause damage to your trailer’s electrical system.
6-Pin Connector Wiring Configuration
| Pin | Function | Wire Color |
|---|---|---|
| 1 | Left Turn Signal and Brake Light | Brown |
| 2 | Auxiliary and Reverse Lights | Yellow |
| 3 | Ground | White |
| 4 | Right Turn Signal and Brake Light | Green |
| 5 | Electric Brakes | Blue |
| 6 | 12 Volt Battery Charge | Red |
When wiring your 6-pin connector, follow the same wiring configuration as the 7-pin connector, but do not connect the blue wire. The blue wire is used for electric brakes, which are not present on trailers using a 6-pin connector.
4-Pin Connector Wiring Configuration
| Pin | Function | Wire Color |
|---|---|---|
| 1 | Left Turn Signal and Brake Light | Brown |
| 2 | Right Turn Signal and Brake Light | Green |
| 3 | Tail and Marker Lights | Yellow |
| 4 | Ground | White |
Wiring your 4-pin connector is the simplest of the three configurations. Simply connect each wire to the corresponding pin according to the wiring configuration above.
Step-by-Step Instructions
Wiring your trailer plug can seem daunting at first, but it is actually a fairly simple process. Follow these step-by-step instructions to wire your trailer plug correctly.
Step 1: Gather Your Materials
You will need a few basic tools to complete this task:
- Wire cutters/strippers
- Crimping tool
- Electrical tape
- Trailer plug
- Wiring harness
Step 2: Trim the Wires
Trim the ends of the wires that will be connected to the trailer plug. Use wire cutters to remove any excess wire, and strip the ends of the wires using wire strippers so that about half an inch of bare wire is exposed.
Step 3: Connect the Wires to the Plug
Follow the wiring configuration for your trailer plug to connect each wire to its corresponding pin. Use a crimping tool to secure each wire to its pin. Once all the wires are connected, wrap each wire in electrical tape to protect the connections.
Step 4: Test the Connections
After wiring your trailer plug, test the connections to make sure everything is working properly. Connect your trailer to your F350 and turn on your vehicle’s lights, brakes, and other auxiliary functions. Check that all the lights on your trailer are functioning correctly.
FAQs
What is the difference between a 6-pin and 7-pin trailer plug?
The main difference between a 6-pin and 7-pin trailer plug is the presence of electric brakes. The 7-pin connector has an additional pin for electric brakes, while the 6-pin connector does not.
What are electric brakes and why do I need them?
Electric brakes are brakes that are activated by an electric signal from your vehicle’s braking system. They provide additional stopping power and make towing heavier trailers safer. If your trailer is over 3,000 pounds, it is required to have electric brakes in most states.
Can I wire my trailer plug myself?
Yes, wiring your trailer plug is a fairly simple task that can be done by most DIY enthusiasts. However, if you are not comfortable working with electrical systems, it is recommended that you have your trailer plug installed by a professional.
What if my trailer plug is not working?
If your trailer plug is not working, the first thing you should do is check the wiring connections. Make sure that all the wires are connected to their corresponding pins and that they are properly secured. If the connections are secure and the plug is still not working, you may have a problem with your trailer’s electrical system or a blown fuse.
Where can I buy a trailer plug?
You can purchase trailer plugs at most auto parts stores or online retailers that specialize in trailer parts and accessories.
