iDatalink HRN-HRR-SU2
This HRN-HRR-SU2 interface harness from iDatalink allows you to connect a new iDatalink-ready car stereo in select 2012-21 Subaru, Scion, and Toyota vehicles, working in conjunction with iDatalink's Maestro ADS-MRR or ADS-MRR2 module. Once connected, you'll retain the use of your Subaru's steering wheel audio controls. You'll also keep your vehicle's's amp and subwoofer (if present) as well as the factory Starlink connection and secondary vehicle display (if equipped) and vehicle backup camera (front and side camera retention requires a second camera input on your aftermarket receiver). You'll also be able to display factory vehicle settings, engine performance data, and other vehicle info on your receiver's screen. The harness also provides accessory power and illumination outputs, and provides the outputs (parking brake, reverse light, and speed sense) you'll need to install a navigation receiver.
The package includes three connectors that plug in between the Maestro module, your vehicle radio's wiring plugs, and your new car stereo. You'll have to solder or splice together this harness's power/ground, illumination, and speaker output wires to the corresponding wires on your aftermarket receiver's wiring harness.
Plug directly into your new stereo
This harness also features an in-line head-unit connector harness, which will plug into their new "Head-unit direct" harnesses for select radio brands, which eliminate the need to splice any wires. If you're installing a radio that doesn't work with a "Head-unit direct" harness, you simply cut off the plug and connect the wires to the harness included with your new radio.
Installation Note: The HRN-HRR-SU2 adapter must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect any new car stereo to your Subaru, Scion, or Toyota vehicle.

Worked great to connect my 2015 Subaru Outback to the iDataLink Maestro RR and my new Alpine Head Unit! Only had a single wire (speed sensor) to connect outside of the harnesses that Crutchfield recommended to me.
