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.

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 & sold separately.

correct harness

Written By DH, ky on Tuesday, February 24, 2015

Fots with xorrect color match to a 2007 ford freestyle

Pros: Easy color match install to my jvc head unit

Cons: None. It works great

Easy instructions, worked perfect

Written By RickS, Skowhegan, ME on Thursday, February 19, 2015

Instructions were easy to go by, just wish they had the butt connectors supplied with the adaptor.

Pros: Great instructions

Cons: No butt connectors, but that is not that big an issue.

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.

Multiple fits

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

Plug and Play

Written By Bandit, Birmingham, AL on Saturday, January 03, 2015

Crutchfield Customer Review (What's this?)

Perfect for my 2004 F150. No cutting up the factory harness and the colors were spot on with the Pioneer aftermarket unit I installed. Made the install so much easier!

Pros: Quick and easy.

Cons: None.

Crutchfield Customer Review (What's this?)

Fits just like it should. Makes install of an aftermarket head unit easy.

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."

Great Harness

Its a harness

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.

Written By GeoffB, Bedford, MA on Friday, October 03, 2014

Crutchfield Customer Review (What's this?)

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.

Pros: Good quality and easy installation. Colors matched my radio perfectly.

Cons: none

Ford Freestar Radio Connector Adapter

Written By Stephen M, Cincinnati on Saturday, July 05, 2014

Crutchfield Customer Review (What's this?)

The adapter works well enough, but there were two wires that were green with black stripes. One was also marked with several gold dashes as were several other wires. The other wires were all Positive conductors, so I made the assumption that all wires with the gold dashes were Positive. I tested my theory by connecting the harness with wire nuts before soldering all connections. The temporary hookup worked perfectly. As always, I then soldered all of the connection and used heat-shrink tubing to insulate all of the conductors. With this and a few well-placed zip-ties and the final result is a professionally finished harness.

Pros: The adapter works just fine.

Cons: The instructions were a bit vague and not recommended for amateurs.

Always cleaner install with adaptor, no splicing required (for the most part; see cons below).

Pros: Greatly reduces installation time, no need to remove or modify factory wiring harness.

Cons: I'm not sure if this was just a fluke but the pins for aux 12vdc and power antenna on mine was in the incorrect place. No big deal really but did add a few minutes of troubleshooting time.
