Metra 70-1731 Wiring Harness
This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.
First, attach the color-coded wires on your Crutchfield-supplied harness to the wires from your new stereo. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here.
Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness makes installing your new stereo easier, and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease.
The harness also includes an adapter for Metra's ASWC-1, which allows you to keep your steering wheel controls. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Saved me a tone of time! Worked with both our 2017 and 2018 Civic Hatchbacks. All you need to do is wire up the HU to the harness and it's good to go. We also needed to purchase a USB port retention cable, Metra ax-cam6v, and the universal steering wheel control adapter to keep all functions.
