Metra 70-2105 Receiver 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. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Features

Crutchfield Wiring Harness: Crutchfield wiring harnesses prevent 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.

Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Wiring Notes: If the Crutchfield wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicle's may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required and sold separately.

Marginal

Crutchfield Customer Review (What's this?)
 
Plain harness. It doesn't allow you to interface for the steering wheel adapter, and requires a separate wire to connect to power. This not what I expect from a Crutchfield supplied harness. It could have power built in.
Pros:
Limited functionality
Cons:
Many

They know nothing

Written By Photog, Englewood, FL on Thursday, April 03, 2014
Crutchfield Customer Review (What's this?)
 
Perfect for what I needed , I went looking for same harness at the local big box store in Port Charlotte FL , and the sales man told me i needed a $150 harness or I would never get the radio to work , I told him that he must be wrong and thats outrageous but he insisted , needless to say , He was wrong.
Pros:
Fits perfect , match wire for wire.
Cons:
Non , The only con with this CAR is that you have to pull your own acc. wire from fuse box but thats the cars wiring not the conversion harness. The harness even comes with the acc. wire needed.

Aveo Wiring Harness

Written By TechyinIdaho, Boise, ID on Sunday, January 05, 2014
Crutchfield Customer Review (What's this?)
 
This wiring harness made installation super easy. I installed the Deck and four speakers in just about 2 hours start to finish. The hardest part was removing dash and door pieces carefully as not to break anything.
Pros:
Perfect fit, easy because of color coding matched car.
Cons:
Wire ends aren't stripped, so you have to strip them back yourself.

Upgrade from factory stereo

Written By JustinH, Oliver springs, TN on Tuesday, November 12, 2013
Crutchfield Customer Review (What's this?)
 
I installed this unit into my wife's Chevy Aveo. It replaced the factory CD receiver and greatly improved the sound quality with the OEM speakers. The Pro EQ feature offers the flexibility to tweak the sound to your preference( especially handy when dealing with original speakers). Just added a 400 watt 2 channel amplifier (also a JVC product) for driving an Alpine type E 12" subwoofer. I am 100% satisfied with this product! Its relatively easy to use, comes with a remote and offers plenty of functions to customize your vehicle's sound system.
Pros:
Price, sound quality, features and remote
Cons:
none for this price range

Reciever wire harness

Written By Edg, Lv nv on Thursday, July 18, 2013
Crutchfield Customer Review (What's this?)
 
Exactly what was needed for 2011 Chevy Aveo. Easy install, just match the colors and connect! Hardest part was taking dash apart. Power wire not compatible with certain models. But separate power wire comes with harness.
Pros:
Easy install. Very simple to follow colors of wires.
Cons:
Separate power wire (comes with kit). You must connect to audio fuse in fuse block to get power, but spade needs to be filed down to fit into wire connector. Easy to do though.

It took me a long time to find a wire harness for my 2011 Chevy Aveo5 LT, and when I found this one I was afraid that it would not work. However, the harness works perfectly and even powers all 6 speakers in my car!
Pros:
Works on all 6 speakers. Clear directions.
Cons:
None.

Metra 70-2105 Receiver Wiring Harness

Written By Anonymous, Washougal, WA on Friday, May 18, 2012
Crutchfield Customer Review (What's this?)
 
I like this harness adapter but the fuse splice you have to use is a larger spade than the supplied female on the harness!
Pros:
Better than hacking apart your factory harness!
Cons:
Did not come with correct connection for fuse!
