The 2014 Chevy Silverado is a powerful pickup truck that can tow heavy loads. However, to tow a trailer, you need to have a functioning trailer wiring system. In this article, we will cover the basics of the 2014 Chevy Silverado trailer wiring diagram, including the different types of connectors, wiring colors, and installation tips.
Types of Connectors
There are four types of connectors used in the 2014 Chevy Silverado trailer wiring system:
- 4-pin flat connector
- 5-pin flat connector
- 6-pin round connector
- 7-pin round connector
4-pin Flat Connector
The 4-pin flat connector is the most basic and common type of trailer connector. It has four pins, which correspond to the following wires:
- Ground wire (white)
- Left turn/brake light wire (yellow)
- Right turn/brake light wire (green)
- Taillight wire (brown)
This type of connector is suitable for small trailers with basic lighting systems that don’t have brakes or a reverse light.
5-pin Flat Connector
The 5-pin flat connector is similar to the 4-pin flat connector, but it adds a blue wire for the electric brake controller. The pin configuration is as follows:
- Ground wire (white)
- Left turn/brake light wire (yellow)
- Right turn/brake light wire (green)
- Taillight wire (brown)
- Electric brake wire (blue)
This type of connector is suitable for small trailers with electric brakes.
6-pin Round Connector
The 6-pin round connector is a less common type of connector that is used for larger trailers that have electric brakes. The pin configuration is as follows:
- Ground wire (white)
- Left turn/brake light wire (yellow)
- Right turn/brake light wire (green)

- Electric brake wire (blue)
- 12V power wire (black)
The 12V power wire is used to charge the trailer’s battery while driving.
7-pin Round Connector
The 7-pin round connector is the most advanced type of trailer connector, and it is used for large trailers that have multiple lighting systems, electric brakes, and other features. The pin configuration is as follows:
