The 2017 Ford F350 pickup truck is one of the strongest vehicles in its category. If you own one, you understand how important it is to ensure that everything is working correctly, including the tail lights. In this article, we will go through the wiring diagram for the 2017 F350 tail lights, including some frequently asked questions.
What Are Tail Lights and Why Are They Important?
Tail lights are an essential component of any vehicle as they serve as a warning device for other drivers on the road. They indicate to other drivers that you are slowing down, stopping or turning, which helps prevent accidents. Additionally, tail lights are required by law, so it’s essential to ensure that they are working correctly at all times.
How Do Tail Lights Work?
Tail lights are powered by electricity from the truck’s battery, which flows through a series of wires and circuits to illuminate the bulbs. The switch that controls the tail lights is typically located on the dashboard of the vehicle, and when it is turned on, it sends a signal to the tail light relay. The relay then sends power to the tail lights, which causes them to illuminate.
When the brake pedal is pressed, a signal is sent to the brake light switch. This, in turn, triggers the brake light relay, which sends power to the brake lights, causing them to illuminate.

2017 F350 Tail Light Wiring Diagram Breakdown
Black Wire (Ground/Negative)
The black wire serves as the ground or negative wire in the tail light circuit. It connects to the metal frame of the truck and completes the circuit, allowing the tail lights to work correctly.
Green Wire (Tail Light)
The green wire is responsible for powering the tail lights. When the switch is turned on, power flows through the green wire to the tail light bulbs, illuminating them.
Yellow Wire (Left Turn Signal)
The yellow wire is responsible for powering the left turn signal when activated. When the turn signal is turned on, power flows through the yellow wire to the left turn signal bulbs, causing them to flash.
Dark Green Wire (Right Turn Signal)
The dark green wire is responsible for powering the right turn signal when activated. When the turn signal is turned on, power flows through the dark green wire to the right turn signal bulbs, causing them to flash.
Red Wire (Brake Lights)
The red wire is responsible for powering the brake lights when the brake pedal is pressed. When the brake is applied, power flows through the red wire, causing the brake lights to illuminate.
White Wire (Reverse Lights)
The white wire is responsible for powering the reverse lights when the vehicle is put in reverse. When the reverse gear is engaged, power flows through the white wire to the reverse light bulbs, causing them to illuminate.
2017 F350 Tail Light Wiring Diagram FAQs
What Should I Do If My Tail Lights Stop Working?
If your tail lights stop working, the first thing to do is check the bulbs. If the bulbs are not the issue, check the wiring to see if there are any broken or loose connections. Additionally, make sure that the fuses are not blown. If all these checks out fine and the tail lights still do not work, seek the help of a professional mechanic.
Can I Install LED Tail Lights in My 2017 F350?
Yes, you can install LED tail lights in your 2017 F350 as long as they comply with the local laws and regulations. LED tail lights are generally more efficient, brighter and longer-lasting compared to traditional bulbs.
Do I Need to Replace Both Tail Lights Even If Only One Is Not Working?
Yes, it’s recommended that you replace both tail lights even if only one of them is not working. This is because the other light might be close to failure, and replacing both ensures that the lights function correctly and have a uniform appearance.
How Can I Test My Tail Lights Before Driving?
To test your tail lights, turn on the headlights and walk around the back of the truck to see if they are working correctly. Additionally, have someone press the brake pedal and activate the turn signals while you check to see if they are functioning correctly.
