5. Setup and Installation
This wiring harness simplifies aftermarket stereo installation by connecting to your vehicle's factory wiring without modification. Follow these steps for a successful setup:
General Wiring Principles:
The harness features pre-stripped wires with standardized color codes. Match the wires from the RED WOLF harness to the corresponding wires on your new aftermarket stereo's harness. Common connections include:
- Yellow: 12V Constant Power
- Red: 12V Accessory Power
- Black: Ground
- Orange/White: Dash Light/Illumination
- Blue: Power Antenna/Amplifier Turn-On (connect to 12V power if using an amplified antenna adapter)
- Speaker Wires (e.g., White, Gray, Green, Purple with solid and striped variants): Connect to corresponding speaker outputs.
For best results, solder connections and use heat shrink tubing for durability and proper insulation.

- Remove Factory Radio: Carefully remove your vehicle's existing factory radio and any surrounding trim panels to access the wiring.
- Connect Harness to Aftermarket Stereo: Match the colored wires of the RED WOLF harness to the corresponding wires on your new aftermarket stereo's harness. Crimp or solder these connections securely.
- Connect Harness to Vehicle: Plug the RED WOLF harness into the factory wiring connector in your vehicle's dashboard.
- Connect Antenna (if applicable): Connect any necessary antenna adapters.
- Test Connections: Before fully reassembling, reconnect the battery and briefly turn on the stereo to ensure all functions (power, audio, balance, fade) are working correctly.
- Reassemble: Once confirmed, secure the new stereo in place and reattach all trim panels.
