Understanding the Wiring Diagram
Before we get started on the wiring process, it’s important to understand the wiring diagram. The diagram will show you the different wires that connect to your radio and where they need to be connected.

It’s important to use the correct wiring diagram for your specific Nissan Murano model year, as the wiring can differ between years.
Power Supply
The power supply wires are responsible for providing power to your radio. There will typically be a few different wires labeled “power” or “battery” that you will need to connect.
Make sure to connect these wires to the correct terminals on your radio. Incorrect wiring of the power supply can cause damage to your radio or car.
Speakers
The speaker wires are responsible for connecting your radio to the speakers in your car. There will typically be eight wires labeled “speaker” that need to be connected.
Make sure to connect the correct wire to each speaker, as incorrect wiring can cause the speakers to not work or produce poor sound quality.

The antenna wire is responsible for receiving radio signals. You will typically only have one antenna wire to connect.
Make sure to connect this wire to the correct terminal on your radio, as incorrect wiring can cause poor signal quality.
