About the Metra 70-1731 Wiring Harness

Metra 70-1731 Wiring Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

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.

It works!

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.

Metra 70-1731 Wiring Harness

Crutchfield customer from NH on 12/31/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

harness works for 2017 civic sport, but you will NOT retain factory usb and mic. you will need an adapter for usb to retain factory usb inputs in your vehicle. I had issues with the back up camera installation, the 12v to 6v power adapter did not work and i ended up with black screen. not enough voltage to run the camera. apparently the backup camera i have is an 8v camera, so i had to wire its power to a acc power source (head unit.) The camera works perfectly for now with 12v supplied power, but stays on constantly while the head unit is on. It is still to be determined on how long it will last. You will not retain the factory 3 different camera views in 2017 civic sport once you get the factory camera working other then those issues i had, everything else works fine.

Pros: adapter for steering wheel controls

Cons: mic and usb connections

Fit my 17 civic no problems. Everything is clearly labeled. Connect a few wires and your in business. I couldn't imagine not having this.

Pros: Wires easy to splice. Plenty of wire lead length. Makes adding stereo steering wheel controls so much easier.

Cons: None

Features

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

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.
