Vehicle-specific harness for Mazda upgrades

This iDatalink HRN-HRR-MA2 installation harness connects aftermarket head units to select Mazda vehicles built between 2014 and 2020. It works with the Maestro ADS-MRR or ADS-MRR2 module to integrate the new radio with the factory electrical system. Optional head unit adapters are available for Alpine, JVC, Kenwood, Sony, and Pioneer receivers.

Replaces the factory radio plug while keeping

The harness retains steering wheel audio controls and factory amplifier functionality after the original head unit is removed. It also preserves the use of the existing rear-view camera. The jump is worth it when you want a modern receiver without losing these integrated vehicle functions.

Supports front, side, and 360 camera views

Engine performance data can be displayed on the touchscreen when paired with select aftermarket receivers. The harness handles camera integration and data display for supported Mazda models, but it requires the separate Maestro ADS-MRR or ADS-MRR2 module to function. It does not support vehicles outside the 2014 to 2020 Mazda range.

Questions about this item

Does the HRN-HRR-MA2 harness plug directly into the Mazda's factory wiring without cutting?

Yes, the harness is designed for select Mazda vehicles from 2014 to 2020 and provides a direct connection to the vehicle's electrical system for aftermarket head unit installation.

Which module must be connected to the harness before programming the steering wheel controls?

The Maestro ADS-MRR or ADS-MRR2 module is required and must be connected to the harness to retain steering wheel audio controls and factory amplifier functionality.

Will the rear-view camera input on this harness need a separate adapter when the vehicle has a 360-degree camera system?

Front, side, and 360 cameras are supported with compatible aftermarket radios, and the harness preserves the rear-view camera without an additional adapter for those functions.
