Power Source
The power source is the first component in the wiring diagram. It is the source of power for all the lights and signals on your trailer. On the 2002 Chevy 1500, the power source is connected to the battery. This ensures that you have a steady flow of power to your trailer lights, even if your truck’s battery is not fully charged.

Trailer Connector
The trailer connector is the component that connects your truck’s wiring system to your trailer’s wiring system. This allows you to transfer power and signals from your truck to your trailer. On the 2002 Chevy 1500, the trailer connector is a 7-pin connector.
Wiring the Trailer Connector
To wire the trailer connector, start by removing the cover on the connector. Then, use a wire stripper to remove about 1 inch of insulation from each of the wires. Next, match the colors of the wires on your truck to the corresponding colors on the trailer connector. Connect each wire securely, making sure there are no loose connections.
