2013 Silverado Trailer Wiring Diagram

If you own a 2013 Silverado and need to tow a trailer, it’s important to have the correct wiring diagram. This will ensure that your trailer’s lights and brakes work properly and that you stay safe on the road. In this article, we’ll provide you with a detailed wiring diagram and answer some frequently asked questions about towing with your Silverado.

Wiring Diagram

The wiring diagram for a 2013 Silverado trailer is fairly simple. Your truck should have a seven-pin connector on the rear bumper, which is where you’ll connect your trailer’s wiring. Each pin on the connector has a specific function, which we’ll explain in more detail below:

Pin Function
1 Left turn/stop
2 Reverse lights
3 Ground
4 Right turn/stop
5 Electric brake
6 12V power
7 Auxiliary

To connect your trailer to your Silverado, you’ll need to match up the corresponding pins on your trailer’s connector to the pins on your truck’s connector. This can be done using a wiring harness, which is often sold separately.

Pin 1 – Left turn/stop

This pin is responsible for sending power to your trailer’s left turn signal and brake lights. When you activate the left turn signal or step on the brakes, the corresponding lights on your trailer should also light up.

Pin 2 – Reverse lights

The reverse lights on your trailer are connected to this pin, which is controlled by your truck’s transmission. When you put your truck in reverse, the reverse lights on your trailer should also turn on.

Pin 3 – Ground

This pin provides a ground connection between your truck and your trailer, which is necessary for proper electrical function.

Pin 4 – Right turn/stop

This pin is similar to pin 1, but controls the right turn signal and brake lights on your trailer.

Pin 5 – Electric brake

If your trailer has electric brakes, they’ll be controlled by this pin. When you step on the brakes in your truck, the electrical signal will activate the brakes on your trailer.

Pin 6 – 12V power

This pin provides 12V power to your trailer’s battery, allowing it to charge while you’re driving. It can also be used to power accessories on your trailer, such as interior lights or a fridge.

Pin 7 – Auxiliary

This pin can be used for a variety of purposes, depending on your specific trailer setup. It’s often used to power backup cameras, interior lights, or other accessories.
