The 2014 Nissan Altima is a popular mid-size sedan that offers advanced technology features including Bluetooth connectivity and a sophisticated audio system. However, if you need to install a new radio or replace the old one, you will need to know the correct wiring diagram.
Why You Need a Wiring Diagram
Before you start installing a new radio, it’s important to get the correct wiring diagram for your car. A wiring diagram shows the electrical connections between different components and how they are connected. With this information, you can understand how the radio is connected to the car’s electrical system and avoid damaging any of the components.
Additionally, a wiring diagram can help you identify the color codes of the wires, which will make it easier to connect the new radio correctly. Without a wiring diagram, you may end up guessing which wire goes where and causing unnecessary damage to your car.
Where to Find the Wiring Diagram
The wiring diagram for a 2014 Nissan Altima can be found in the owner’s manual or on the Nissan website. You can also find it in aftermarket service manuals or by searching online.
It’s important to make sure you get the correct wiring diagram for your specific model and trim level, as different models may have different options and features that impact the wiring.

Section 1: Power Supply and Ground
This section shows the power supply and ground connections for the radio. The radio requires two types of power: constant power that keeps the memory and clock settings intact, and switched power that turns the radio on and off with the ignition.

The 2014 Nissan Altima can be equipped with steering wheel controls that allow you to adjust the volume, change the radio station, and skip tracks without taking your hands off the wheel.
