One of the worst things about factory car radios is their wiring color schemes.

Unlike aftermarket car radios, they don’t have any standardized color coding. The same car manufacturer will have different color codes depending on the vehicle series and year.

The same is the case with Nissan, which uses different color coding for various series, such as Almera, Navara, Sentra, etc.

This non-uniformity makes it difficult for car enthusiasts to identify potential radio issues. Before anything else, they must review the owner’s manual to check wiring diagrams and determine which color represents which wire.

Therefore, we have listed radio colors for different Nissan vehicles series/years to simplify this task.

Conclusion

These were the radio wiring color codes for different Nissan models. You must remember that the primary purpose for listing these color codes is to help you diagnose Nissan car radio problems.

However, you should never directly connect with the factory harness in radio installation. That’s because the direct wiring connections will complicate future upgrades (as you’ll have to cut the previous connections before making new ones).

Instead, use an aftermarket wiring harness made specifically for your vehicle.
