Metra 70-5520 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 saves installation time since you won't have to cut factory wires individually, and this also enables you to re-install the factory radio if needed. 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.

Connections:

  • 12V constant power
  • 12V switched power
  • chassis ground
  • dimmer
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-
  • right rear speaker +/-

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.

'07 Hyundai Sonata

Written By David, Maryland on Saturday, July 25, 2015

Crutchfield Customer Review (What's this?)

I wish I had read the review from the guy in Florida sooner and saved me the frustration. It is missing pin connection 24 for my '07 Hyundai Sonata; the infamous black/green wire. I did not know that and experienced poor to no AM radio reception. After struggling with this for a couple days, called Crutchfield and talked to tech support. Told to splice into the wire harness on the vehicle. After doing so, it worked like a charm. This is why I use Crutchfield!! The only thing that would have made this product better is to have a wire included with this harness that could be plugged into the missing port so one would not have to splice into the vehicle harness. Thanks Crutchfield tech support for the answer. Very happy it works!!

Pros: Other than the missing green/black wire issue, worked perfectly. Made rest of install easy.

Cons: Really think that a wire could be supplied with kit to address the antenna and green/black wire issue for Hyundai's.

Overall made quite well only problem did not include the wire for my steering wheel control so I still had to tap into the factory harness. Used on 2006 Mercury Monterey with Jvc kw-v50bt and steering wheel SWI Rc. Didn't even need the instructions all wires color coded and labeled well.

Pros: Well made easy to install.

Cons: No wire for retaining steering wheel controls.

Almost Perfect, But....

Written By David, Florida on Monday, June 08, 2015

Crutchfield Customer Review (What's this?)

Almost perfect but one glaring flaw - it is missing one wire in the harness, the infamous Hyundai "frog" wire. The pinout instructions sent by Crutchfield show it as missing and point to the EMPTY pin slot with the note, quote, "For all 2006-'08 Hyundai Sonatas: Connect the Power Antenna Wire on the new receiver to the factory Green/Black Wire matching this location (bottom of illustration) on the factory harness disconnected from the factory radio."

This is a REAL problem if you need this wire. The only solution is to cut into the car's wiring harness and rig your own wire or connector around this one.

Pros: Has MOST of the wires you need.

Cons: Missing one wire in the harness.

Crutchfield Customer Review (What's this?)

Plugs directly into factory harness. Has bare wires to be connected to aftermarket harness. Works good.

Pros: Works as designed Wires right length (long enough to allow movement of radio while placing, but not too long/cumbersome) Easy to use

Cons: No crimp connectors (not surprising, but would have made the product better)

Perfect in every way.

Written By Bill, Ohio on Monday, May 18, 2015

Crutchfield Customer Review (What's this?)

Just like Mary Poppins as "Practically Perfect In Every Way". Wiring instructions make this adapter kit painless and SO easy. This was my third adapter purchased from Crutchfield and all 3 for my other installs were equally as easy. A MUST HAVE for anyone's install project.

Pros: Great instructions.

Cons: Gray and gray-black wire colors were a bit difficult to differentiate.

All I can say is WOW!

Written By HeavyWalker, Lima, Ohio on Monday, April 06, 2015

Crutchfield Customer Review (What's this?)

All I can say is WOW! I had not installed a stereo in a car for over 20 years. The Metra harness adapter made my install on my wife's Focus go so smoothly it was almost unbelievable. No meters to read or making educated guesses about which wire is which. Just match color for color while following along with the instructions and the manual for the receiver. Again, so easy and full proof I can not say enough. But I can say this, MY CAR IS NEXT!! And you can beat the farm I will order these again for the receiver and the new speakers. And Crutchfield's "What Fits My Car" section of the website was dead on perfect and everything arrived in 2 days as promised in perfect condition. Best thing of all, my install of the Crutchfield stereo saved me $200 compared to the local stereo shop guys. THANKS CRUTCHFIELD, SEE YOU ON THE NEXT ORDER.

Pros: EVERYTHING. These !@#$ing things rock. I wish I would have known about these 20 years ago.

Cons: NONE

Metra wiring harness

Written By Derek G, Chester, Virginia on Thursday, February 05, 2015

Crutchfield Customer Review (What's this?)

At first, I was upset because I had to connect the receiver harness to the Metra harness. I was under the impression that it all came set up ready to plug in. But the included wiring diagrams sent via e-mail from Crutchfield were very clear and precise. The Metra harness wire color codes matched those of the harness for the receiver. The color shades were a bit different, but green was green, green/black was green/black, etc. You will need to purchase the appropriated closed end crimp connectors and a crimping tool if you do not already have them. You will also need a small guage wire stripper as well to strip the ends of some of wires that are not prepped. All in all it was 12 connections that I had to make. Don't let this intimidate you though. This can be done inside on the kitchen table before you take it out to install. It is very easy since all the color codes matched up.

Pros: - You do not have to splice into your factory harness - Color codes all matched making wire pairing a snap

Cons: - You may need to buy tools and connectors

Does Not Fit '03 Grand Marquis

Written By CL.MA, Phila. PA on Thursday, January 29, 2015

I ordered this for an '03 Grand Marquis and it is not even close to a proper fit. This harness is about 2 inches wide and the connector on the car is very small, about 1 inch. Would not recommend anyone buy this.

Written By Timf, Crowley, Texas on Sunday, January 18, 2015

Crutchfield Customer Review (What's this?)

I have a Ford Focus, so it was confusing when the instructions talked about other brands of vehicles. In the end I just followed the color codes on the instructions and they matched exactly with the Sony Radio I was installing.

Pros: Fit my 2006 Ford Focus

Cons: No included wire nuts or crimp connects. I soldered my wires, so that was not really an issue with me.

Perfect Fit for 2009 Fusion

Written By JeffR, Michigan on Wednesday, January 07, 2015

Crutchfield Customer Review (What's this?)

This connector harness fit perfectly in our 2009 Ford Fusion. Be sure to keep the plastic bag that the harness comes in so you can reference the connection colors on the back of the bag. I couldn't imagine trying to splice directly into the factory harness of the car and not using this Metra harness. It is so much easier with the harness and worth the $10 to avoid working with the short factory harness in the car.

Pros: Easy to work with and good fit to factory connector.

Cons: None

Straight forward

Written By Ed S, Nebraska on Wednesday, December 03, 2014

Crutchfield Customer Review (What's this?)

Easy; complete. Makes hooking up the radio to the Hyundai a snap. My only problem, which was handled with a call to Crutchfield, was that the stock radio had two connectors but the instructions only referred to one. Turns out only one is needed and that these cars often have two, one of which is apparently not needed - which seems odd to me - but the new radio is working perfectly.

Pros: Matches the car's harness as it should.

Cons: Instructions didn't mention the extra connector from the stock radio. Seems like they could add a line saying "ignore the orange plug from your stock radio."

Written By TheBurns, Moscow, PA on Tuesday, November 04, 2014

Crutchfield Customer Review (What's this?)

There isn't much that I can say about this harness. I have a 2004 F150 XLT with a factory single disc, AM/FM, Cassette stereo without premium sound and without factory sub. This harness plugged right into my factory wiring. I soldered the ends of this and the head units harness for the best possible connection then finished off with some high quality shrink tubing. This is highly recommended no matter the installation. All the wires work and connect up as they should and are color coded to match aftermarket head unit wiring. I know some have issues in other makes but I can only speak for my own install. It works as it should.

As I'm new at this radio installation stuff I was a little nervous about doing my own wiring. The instructions that Crutchfield were pretty good but I did end up needing to call a couple times for help. Crutchfield really knows what they are doing and were very helpful with installation questions. The wiring harness is of good quality, the wire ends are pre-stripped (makes life easier) The colors matched my new radio perfectly so I can't complain.
