Pairing the Backup Camera
1. Make sure the trailer marker lights are turned on. The camera is powered through the marker lights.
2. There is a pairing button in the wiring to to camera. It is located behind the cloth panel at the back of the bed in the center. You would need to reach down behind the cloth paneling. There will be a small bundle of wires. Pull them up gently. In that bundle will be the pairing button. Make sure the screen is in pairing mode. Press the button to pair. I have included a picture of the button.
