Setup and Installation

Installation of this wiring harness requires basic automotive electrical knowledge. If you are unsure about any steps, it is recommended to seek professional installation.

1. Wiring Harness Connection

The radio wiring harness connects your aftermarket stereo to the vehicle's factory wiring. Each wire on the harness is color-coded to match standard aftermarket radio wiring. The wires are pre-stripped for ease of connection.

• Match the color-coded wires from the NuIth harness to the corresponding wires on your aftermarket radio's harness.
• For best results, use solder connections and heat shrink tubing to secure all wire connections.
• Ensure all connections are insulated to prevent short circuits.

2. Red Ignition Wire (ACC)

Some vehicle OEM radio harnesses may not include an ignition (ACC) wire. The provided red ignition wire is for these specific cases.

• Connect one end of the red ignition wire to the ACC wire of your aftermarket radio.
• Connect the other end to a reliable 12V accessory power source that is active when the ignition is on. This source is typically found behind the vehicle's ignition switch or in the fuse box.
• Caution: Incorrect connection of the ignition wire can lead to battery drain or improper radio operation. Verify the power source with a multimeter before making the final connection.

3. Antenna Adapter Connection

The antenna adapter ensures your aftermarket radio receives a clear signal from the vehicle's factory antenna.

• Connect the male end of the antenna adapter to the antenna input on your aftermarket radio.
• Connect the female end of the antenna adapter to the vehicle's factory antenna cable.
• Ensure a snug fit for optimal signal reception.

Operating the Aftermarket Radio

Once the NuIth wiring harness and antenna adapter are correctly installed, your aftermarket radio should power on and receive radio signals. Refer to your aftermarket radio's specific instruction manual for details on its operation, features, and settings.

Maintenance

The NuIth Radio Wiring Harness and Antenna Adapter are designed for long-term durability and require minimal maintenance. Ensure all connections remain secure and free from moisture or corrosion. Periodically inspect visible wiring for any signs of wear or damage.

Troubleshooting

• No Power to Radio:
  • Check the vehicle's fuse box for any blown fuses related to the radio or accessory power.
  • Verify the connection of the red ignition wire to a constant 12V accessory source. Use a multimeter to confirm voltage.
  • Ensure the yellow constant power wire is correctly connected and receiving 12V.
• No Sound from Radio:
  • Confirm that the product is not being used with a factory amplified system (e.g., Bose, Infinity, On-Star), as this harness is not compatible.
  • Check all speaker wire connections between the harness and the aftermarket radio.
  • Ensure the aftermarket radio's volume is turned up and not muted.
• Poor Radio Reception:
  • Verify that the antenna adapter is securely connected to both the aftermarket radio and the vehicle's factory antenna.
  • Inspect the antenna cable for any damage or kinks.
• Steering Wheel Controls Not Working:
  • This harness does not retain Steering Wheel Control (SWC) functionality. A separate SWC interface kit is required for this feature.
