4. Setup and Installation
Installation of the NuIth wiring harness involves connecting it between your new aftermarket radio and the vehicle's factory wiring. While the wires are pre-stripped and color-coded for convenience, professional installation is recommended for optimal results and to prevent damage to your vehicle's electrical system.
Installation Steps:
- Disconnect Vehicle Battery: Before beginning any electrical work, disconnect the negative terminal of your vehicle's battery to prevent short circuits.
- Remove Factory Radio: Carefully remove your vehicle's existing factory radio according to your vehicle's service manual.
- Identify Factory Wiring: Locate the factory wiring harness that was connected to your original radio.
- Match Wires: Connect the wires from the NuIth harness to the corresponding wires on your aftermarket radio's harness. The NuIth harness features standard color codes to simplify this process. Ensure all connections are secure, either by soldering and heat-shrinking or using appropriate crimp connectors.
- Connect RCA Plugs: If your vehicle has a factory subwoofer and your aftermarket radio has pre-amp outputs, connect the 8-pin plug's RCA inputs to the corresponding RCA outputs on your new radio.
- Connect Harness to Vehicle: Plug the NuIth harness into the vehicle's factory wiring harness.
- Install Aftermarket Radio: Mount your new aftermarket radio into the dashboard opening.
- Reconnect Battery: Reconnect the negative terminal of your vehicle's battery.
- Test System: Turn on the vehicle and test the new radio's functionality, including all speakers, subwoofer (if connected), and other features.
For detailed wire color code diagrams, refer to your aftermarket radio's instruction manual and your vehicle's service manual.

7. Troubleshooting
If you encounter issues after installing the wiring harness, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to aftermarket radio | Incorrect power wire connection, blown fuse, disconnected battery. | Check all power wire connections (constant 12V, accessory 12V, ground). Verify vehicle fuses and ensure battery is reconnected. |
| No sound from speakers | Incorrect speaker wire connections, speaker wires shorted, radio settings. | Double-check all speaker wire connections for correct polarity and secure contact. Ensure radio volume is up and mute is off. |
| Subwoofer not working | Incorrect RCA connection, incompatible factory system, radio settings. | Verify RCA plugs are securely connected to the aftermarket radio's pre-amp outputs. Confirm your factory system is amplified (this harness is not for non-amplified systems). Check radio's subwoofer output settings. |
| Intermittent audio | Loose connections, damaged wiring. | Inspect all wire connections for looseness. Check for any visible damage to the harness wires. |
If issues persist, consult a professional car audio installer or contact NuIth customer support.
