Dash Removal for Radio Access

Ensure the ignition is off and disconnect the negative battery terminal before starting. Remove trim panels around the radio using a trim removal tool to avoid damage. Gently pull out the dashboard bezel, releasing clips carefully; no force is needed due to the simple clip system.

Radio Installation Wiring Steps

Disconnect the old radio harness and connect the new radio using a vehicle-specific wiring harness adapter to avoid cutting wires. Key connections include:

  • Constant 12V wire (red): Connect to battery power source.
  • Switched 12V wire (yellow): Link to ignition switch for on/off control.
  • Ground wire (black): Secure to chassis ground point.
  • Speaker wires: Match positive and negative terminals for each channel.
  • Antenna plug: Attach directly to the antenna adapter.

Reassemble the dash after testing the radio for proper functionality.
