Simplifies the Installation
iDatalink’s iDatalink HRN-HRR-MA1 installation harness simplifies the installation of the Maestro ADS-MRR or ADS-MRR2 Car Radio Replacement Interface module (sold separately) in select Mazda vehicles when replacing your factory radio.The package includes a harness that plugs in between the Maestro module, your factory radio’s wiring plugs, and the serial port on your new car stereo.
in-line Head-unit Connector Harness
This harness features an in-line head-unit connector harness, which will plug into their new “Head-unit direct” harnesses for select radio brands. If you’re installing a radio that doesn’t work with a “Head-unit direct” harness, simply cut off the plug and connect the wires to the harness included with your new radio.
Retains Your Vehicle’s Steering Wheel Audio Controls
The HRN-HRR-MA1 harness and interface module retains your vehicle’s steering wheel audio controls, factory amplifier, and backup camera with any aftermarket receiver with a composite video camera input. The harness also supplies the outputs (parking brake, reverse, and VSS [Vehicle Speed Sense]) necessary for installation of a navigation receiver, plus illumination and accessory power outputs.
