ARC Audio IDATA-OEM-Digital Adapter Harness


The ARC Audio IDATA-OEM-Digital adapter harness is a required accessory when integrating an ARC Audio Pro-Series DSP with any iDatalink Maestro Amplifier Replacement Module—including the AR, AR2, and A2B modules (each sold separately), along with the corresponding vehicle-specific iDatalink Maestro T-harness (sold separately by iDatalink).


This harness is specifically designed for vehicle applications where the factory audio signal is transmitted via a digital carrier, rather than analog. Unlike the standard IDATA-OEM adapter, the IDATA-OEM-Digital is essential in these digital signal path environments to ensure proper communication and signal integrity between components.


Installation is seamless: the harness connects in-line between the Maestro T-harness and any compatible ARC Audio Pro-Series DSP. When combined with an iDatalink Maestro module, this trio creates a powerful integration solution—maintaining full OEM interface functionality and system control, while enabling full customization of your vehicle's audio experience.


The iDatalink Maestro Amplifier Replacement system is a universal integration solution, compatible with over 1,500 vehicles (model years 2005 and newer). These modules interface with ARC Audio DSP-equipped products to significantly enhance audio performance—particularly in vehicles with premium factory infotainment systems or where traditional radio replacement isn’t feasible.


Note: Vehicle-specific T-harness and Maestro Amplifier Replacement Module are both required and sold separately by iDatalink.
