Introduction
This manual provides instructions for installing and using the ASC Audio 16-Pin Aftermarket Backup Camera Harness. This harness is designed to integrate an aftermarket backup camera with specific Toyota and Scion factory OEM display or navigation radios. It allows the video signal from an aftermarket camera to be displayed on the factory screen, provided the radio has a dedicated backup camera input feature.
Product Overview

Image of the ASC Audio 16-Pin Aftermarket Backup Camera Harness. The harness features two white 16-pin connectors, a yellow RCA video input jack, and exposed red and black wires for power and ground connections. The main wiring is wrapped in black electrical tape.
The harness consists of a 16-pin connector designed to interface with the factory radio, a yellow RCA input for the aftermarket camera's video signal, and additional wires for power and ground connections. It facilitates the connection without modifying the vehicle's original wiring.
Setup and Installation
Important: Installation should be performed by a qualified professional or individuals with experience in automotive electrical systems. Disconnect the vehicle's battery before beginning installation to prevent electrical shorts or damage.
- Access the Factory Radio: Carefully remove the necessary trim panels and components to gain access to the rear of your vehicle's factory OEM display or navigation radio. Refer to your vehicle's service manual for specific instructions on radio removal.
- Locate the 16-Pin Connector: Identify the corresponding 16-pin connector on the back of your factory radio. This harness is designed to plug directly into this port.
- Connect the Harness: Plug the ASC Audio 16-Pin Aftermarket Backup Camera Harness into the designated 16-pin port on the factory radio. Ensure a secure connection.
- Connect Aftermarket Camera Video: Connect the yellow RCA video output cable from your aftermarket backup camera to the yellow RCA input jack on the ASC Audio harness.
- Connect Aftermarket Camera Power: This harness does not provide a 12-volt power wire for the aftermarket camera. You must source 12-volt power and ground for your aftermarket camera from an appropriate location in the vehicle's electrical system. Common sources include the reverse light circuit (for activation when in reverse) or a switched 12V accessory wire. Consult your camera's instruction manual for its specific power requirements.
- Secure Wiring: Route and secure all wiring to prevent pinching, chafing, or interference with moving parts.
- Reconnect Battery and Test: Reconnect the vehicle's battery. Turn on the vehicle and shift into reverse to test the camera functionality. The aftermarket camera's image should appear on the factory radio display.

Operating Instructions

Maintenance
The ASC Audio 16-Pin Aftermarket Backup Camera Harness requires minimal maintenance. Periodically inspect the connections to ensure they remain secure and free from corrosion or damage. Ensure all wiring is properly secured and not exposed to excessive heat, moisture, or physical stress.
Troubleshooting
- No Image on Screen:
- Verify all harness connections to the factory radio are secure.
- Confirm the aftermarket camera is receiving proper 12-volt power and ground.
- Check the RCA video connection between the camera and the harness.
- Ensure your factory radio is a display or navigation model with a backup camera input feature.
- Distorted or Flickering Image:
- Inspect the RCA video cable for damage or loose connections.
- Ensure the camera's power supply is stable and free from electrical interference.
- Test with a different aftermarket camera if possible to rule out camera malfunction.
- Camera Not Activating in Reverse:
