This iDatalink ADS-HRN(SR)-FOR01 interface harness from iDatalink allows you to connect a new car stereo in select 2006-up Ford, Lincoln, Mercury, and Mazda vehicles, working in conjunction with iDatalink's Maestro ADS-MRR module. Once connected, you'll retain the use of your steering wheel audio controls and your factory amp, if present.
The package includes three connectors that plug in between the Maestro module, your Ford radio's wiring plugs, and your new car stereo. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness.
Installation note: The ADS-HRN(SR)-FOR01 harness must be used with the iDatalink Maestro ADS-MRR module to connect a new car stereo to your vehicle.
