What is a Chevy Truck Trailer Plug Wiring Diagram?
A Chevy Truck Trailer Plug Wiring Diagram is a visual representation of the electrical connections found at the trailer connector on your Chevrolet truck. It details the function of each pin on the connector and how those pins are wired to the corresponding circuits within your truck.

This diagram is indispensable for ensuring that all trailer functions, from turn signals and brake lights to running lights and auxiliary power, operate correctly.
These diagrams are typically found in your truck's owner's manual or in service manuals. They are incredibly useful for a variety of tasks:
- Installation: When adding a trailer hitch and wiring harness to a truck that didn't come factory-equipped, the diagram is your blueprint for connecting the harness to your truck's existing electrical system.
