The 2013 GMC Sierra is a fantastic truck, but it’s not without its quirks. One common issue that many owners face is with the backup camera system. If you’re having trouble with your backup camera or need to install a new one, then you’re in the right place.
What Is a Backup Camera?
A backup camera is a system that helps drivers see behind their vehicle when backing up. It’s particularly helpful in larger vehicles like trucks and SUVs where the rear view may be obstructed. The camera is mounted on the rear of the vehicle and sends a video feed to a monitor in the cab.
Why Do I Need a Backup Camera?
Backup cameras are not just a luxury, they’re a safety feature. According to the National Highway Traffic Safety Administration, backup cameras are expected to prevent an estimated 58 to 69 deaths per year.
Do All Vehicles Have Backup Cameras?
No, not all vehicles come with backup cameras. However, they have become much more common in recent years, and they will soon be required on all new vehicles.
The GMC Sierra Backup Camera System
The backup camera system on the 2013 GMC Sierra is fairly straightforward. The camera is mounted on the tailgate handle, and the video feed is sent to the radio head unit. The system is activated when the vehicle is put into reverse.
Common Issues
Despite its simplicity, the backup camera system on the GMC Sierra can experience a few common issues. Some owners have reported a blurry or distorted image, while others have had problems with the camera not working at all. In some cases, the issue may be with the wiring.

How to Use the Wiring Diagram
If you’re not familiar with automotive wiring, then this diagram may look a bit daunting at first. However, it’s actually quite simple once you understand the basics.
The first thing you’ll want to do is locate the wiring harness that connects the backup camera to the radio head unit. You may need to remove some panels or trim pieces to access it.
