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.

Features

Compatibility: The Metra 70-1731 wiring harness is used for installing an aftermarket head unit in a 2016-up Honda Civic LX.

Notes:
  • This wiring harness prevents you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the Crutchfield wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the Crutchfield wiring harness into your vehicle's factory radio plug.
  • Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Retains Factory Backup Camera: The Metra 70-1731 wiring harness includes a male composite video jack which allows you to retain your vehicle's factory backup camera (requires 12V-to-6V adapter - sold separately).

Optional Steering Wheel Control Interface: The Metra 70-1731 wiring harness is pre-wired for the Axxess ASWC-1 steering wheel control interface (120ASWC1, sold separately). By connecting the ASWC-1, you are able to retain your vehicle's factory steering wheel controls when replacing the factory radio with an SWC-compatible aftermarket radio.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
