In this article, we’ll guide you through a detailed 2020 Silverado trailer plug wiring diagram, answering all your questions about how to safely and effectively connect your trailer’s electrical systems to your truck.
What is a Trailer Plug Wiring System?
A trailer plug wiring system is a group of wires that connect your trailer’s electrical system to your truck’s electrical system. The wiring can differ depending on the type of trailer you’re towing and your truck’s make and model.
How Does a Trailer Plug Wiring System Work?
A trailer plug wiring system works by connecting the trailer’s electrical system to the truck’s electrical system. The electrical systems of the trailer and the truck are separate, so the trailer wires must be connected to the respective truck wires.
The trailer plug wiring system includes seven wires that are color-coded for easy identification. The wires consist of a ground wire, four power wires, and two auxiliary wires.
What are the Seven Wires in a Trailer Plug Wiring System?
The seven wires in a trailer plug wiring system are as follows:
| Wire Color | Function |
|---|---|
| White | Ground |
| Brown | Taillights |
| Yellow | Left Turn Signal & Brake Light |
| Green | Right Turn Signal & Brake Light |
| Blue | Electric Brakes |
| Black | Auxiliary Power |
| Red | Auxiliary Power |
How to Connect a Trailer Plug Wiring System to Your 2020 Silverado
Step 1: Install the Trailer Plug Wiring System
The first step is to install the trailer plug wiring system. This can be done either by a professional or by yourself using a wiring kit.
The wiring kit should come with instructions for installation, including a diagram that outlines the connections between the truck and the trailer. The wiring is typically installed near the bumper, and the wires should be routed through the back of the truck bed to connect to the trailer.
Step 2: Connect the Ground Wire
The ground wire (white) is the first wire that needs to be connected. This wire should be grounded to the truck’s frame.
Step 3: Connect the Taillights Wire
The taillights wire (brown) connects the taillights of your trailer to your truck. This wire should be connected to the brown wire in the trailer plug wiring system.
Step 4: Connect the Left Turn Signal & Brake Light Wire
The left turn signal and brake light wire (yellow) connects the left turn signal and brake light of your trailer to your truck. This wire should be connected to the yellow wire in the trailer plug wiring system.
Step 5: Connect the Right Turn Signal & Brake Light Wire
The right turn signal and brake light wire (green) connects the right turn signal and brake light of your trailer to your truck. This wire should be connected to the green wire in the trailer plug wiring system.
Step 6: Connect the Electric Brakes Wire
The electric brakes wire (blue) connects the electric brakes of your trailer to your truck. This wire should be connected to the blue wire in the trailer plug wiring system.
Step 7: Connect the Auxiliary Power Wires
The auxiliary power wires (black and red) are used to power any additional features on your trailer, such as interior lights or charging a battery. These wires should be connected to the black and red wires in the trailer plug wiring system.
