Metra 70-5701 Receiver Wiring Harness

Installation Note: This harness uses your factory amplifier; your new stereo must have one pair of preamp outputs to connect this 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. You can also call an Advisor for more information.

Fit & Worked Perfectly

Written By Ed P., New Hampshire on Tuesday, November 24, 2015

Crutchfield Customer Review (What's this?)

Used to install Alpine head unit with subwoofer out into an Explorer Limited with the Mach audio system. Factory amp & subwoofer worked perfectly. No turn-on thump. All fit nicely, and wire colors matched the Alpine output.

Pros: Perfect fit with factory Mach audio system, including subwoofer. Very easy install.

Cons: none, nada, zilch.

Crutchfield Customer Review (What's this?)

I bought this for a 2003 Mustang with the Mach stereo and replaced with a JVC unit. The wiring was ok , the instructions were not as detailed as I would have thought and had to call Crutchfield for help on some of the wiring which if the instructions were clear for my vehicle I wouldn't had called them, I have installed several radios and this is the 1st I have had an issue with the harness.

Pros: Quality connectors

Cons: All instructions not clear.

2002 Mustang GT mach 460 system

Written By Scarfinger, Toledo, OH on Wednesday, October 01, 2014

Crutchfield Customer Review (What's this?)

-1 star for the Amp Turn-On/Sub Harness plastic connector was too tight. I couldn't get it to snap in. I broke the release tab off. I used channel locks (use at your own risk) to get some extra pressure in the connector to get it to seat as far as it would go. I still didn't get it to snap in but it seemed pretty tight. *Everything else was great. I tried chat for some advice and they gave me the installers phone number which I used 3 times. It was my first car stereo install. Everything sounds great.

Pros: Customer service was great. Wire harness matched up good. My first time installing a car stereo and Crutchfield got me through it.

Cons: Amp Turn-On/Sub Harness plastic connector was too tight.

Wiring harness worked fine on my 2003 Ford Windstar. As always Crutchfield delivered a quality product at a reasonable cost and fast shipping! Just another thought. Crutchfield is the only company that I order from that I have not had to return anything because it wouldn't fit. That means a lot to me. Thank you Crutchfield!

I decided to follow what the other reviewers were saying, and I'm glad I did. This harness fit my 2001 Mustang GT with the Mach 460 audio system. No problems at all. Tie ALL the black grounds together, and hook the two blue wires for the rear amps to your head unit's remote wire. This was my first Crutchfield purchase and I'm happy.

2002 Ford Mustang GT Amp Wiring Harness

Written By Mike, Maryville, TN on Friday, March 29, 2013

Crutchfield Customer Review (What's this?)

Finally after trying other manufactured wiring harness's I found one that works. Everyone else selling a 2002 Mustang harness had the wrong size plug for the amp connection. It looked close but the pins would not line up. I admit I was skeptical about this fitting but others said it would. Worked great!

Pros: Finally found the right connector that works with the Mach 460 amps in my 2002 Mustang GT.

Cons: Not a thing

This worked great with my 02 mustang gt mach 460 system, though there wasnt a need for the baby blue and brown wire harness. With this i added splitters to a seperate amp and sub which sounds great.

Pros: Good product, makes for an easy install

Cons: No need for bby blue and brown wire and one harness needed a bit of push to sit correctly

Just what I needed

Written By Bobby, Fairview, TN on Tuesday, August 07, 2012

Crutchfield Customer Review (What's this?)

There isn't much to say about these really. They work as they say they do. What makes this special though, is that it comes with every piece you need to wire up your stereo properly. It has the main wire harness for your speaker connections and things like that, antenna harness so your antenna has proper power, and the amplifier harness in case you have a factory amp. I didn't need the amp harness, but I did need the antenna one. If I had went to autozone, I would have only gotten the main one and my antenna wouldn't be getting the power it needs, since it is an in glass antenna. Thanks for having the proper parts crutchfield!

Pros: It works It has every harness for the car

perfect wiring

Pros: easy to do

Excellent Harness!

Written By PC, Connecticut on Wednesday, May 16, 2012

Crutchfield Customer Review (What's this?)

The folks at Crutchfield did their homework well with this wiring harness. Crutchfield was the only vendor that had all 3 connectors in a single package/purchase AND with documentation. I compared the actual wiring of this Crutchfield harness to an official Ford electrical manual - Crutchfield got it right!!! Car electrical is not for the faint-of-heart so I can't stress how important it is for a vendor to get it right to save the customer from plugging in a $700 head-unit into faulty/incomplete/hacked-up wiring harness. Nice job Crutchfield!

Pros: The immense benefit of not hacking or splicing into the car electrical system. Can put the stock radio back in in 5 mins with no evidence that an after market head unit was ever installed.

Cons: Yes, that I wasted my time believing that vendors (other than Crutchfield) who should know what they are doing with car electrical connectors for aftermarket head-units, don't.

Not exactly intuitive... but easy enough

Written By JamesR, College Park, MD on Friday, August 05, 2011

Crutchfield Customer Review (What's this?)

All the wires necessary are there, but if you are replacing a bottom line stock stereo it's not exactly intuitive where they all go. Yes, there is a diagram that is helpful, but for a stock unit you are not using most of the wires. End of the day I would get it again, and do it again. Had the whole stereo and speakers replaced 90 min. after the package arrived from Crutchfield. Great job guys!

Product Research


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.
