3. Setup and Installation

Follow these steps for proper installation of your NuIth Radio Wiring Adapter. Professional installation is recommended if you are unfamiliar with car audio wiring.

3.1 Preparation

1. Disconnect the vehicle's battery to prevent electrical shorts.
2. Carefully remove the factory radio from the dashboard. Refer to your vehicle's service manual for specific removal instructions.
3. Identify the factory wiring harness connected to the back of your original radio.

3.2 Connecting the Adapter

The NuIth adapter features pre-stripped wires for easy connection to your aftermarket radio's harness. Match the wire colors from the NuIth adapter to the corresponding wires on your aftermarket radio's harness. Use appropriate crimp connectors or solder for secure connections.

3.3 12V Red Ignition Wire Connection

If your vehicle's OEM radio harness lacks an ignition wire, the included 12V red ignition wire can be used. Connect one end of this wire to the ACC (Accessory) wire of your aftermarket radio. The other end should be connected to the ACC harness position located behind the vehicle's ignition switch or to a switched 12V power source in the fuse box.

2. Connect the aftermarket radio to the NuIth adapter.
3. Secure all connections and ensure no bare wires are exposed.
4. Carefully reinstall the aftermarket radio into the dashboard.
5. Reconnect the vehicle's battery.

4. Operating Instructions

Once the NuIth Radio Wiring Adapter is correctly installed, your aftermarket radio should function as intended. Refer to your aftermarket radio's user manual for specific operating instructions.

5. Maintenance

The NuIth Radio Wiring Adapter requires minimal maintenance. Periodically check all connections to ensure they remain secure and free from corrosion. Ensure the wiring is not pinched or exposed to excessive heat or moisture.

6. Troubleshooting

If you encounter issues after installation, consider the following troubleshooting steps:

• No Power to Radio:
  • Check the vehicle's fuse box for any blown fuses.
  • Verify the 12V constant power wire (typically yellow) and the 12V switched ignition wire (typically red) are correctly connected and receiving power.
• No Sound or Distorted Sound:
  • Ensure all speaker wires are correctly connected to the corresponding positive and negative terminals. Incorrect polarity can cause distorted sound.
  • Confirm that your vehicle does not have a factory amplified system. This adapter is for non-amplified systems only. If your vehicle has an amplified system, a different adapter or bypass may be required.
  • Check for loose connections at both the aftermarket radio and the vehicle's factory harness.
• Incorrect Wire Functionality:
  • Refer to the detailed wiring diagrams (Image 8 and 9) and your aftermarket radio's manual to cross-reference wire colors and functions. Some vehicle models or aftermarket radios may have variations.
  • If a specific wire function (e.g., dimmer, steering wheel controls) is not working, ensure it is correctly identified and connected according to the diagrams.
• Radio Not Turning Off with Ignition:
  • Verify the 12V switched ignition wire (red) is connected to a source that turns off with the vehicle's ignition.
