Metra 70-5008 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.


Important Note: This harness bypasses your factory amplifier. In order to install it and make the necessary connections, you will need to run the harness wires from your receiver location to your factory amp location, which may be in the rear of your vehicle.

Crutchfield Customer Review (What's this?)

I shopped at local discount retailer and bought 2 connectors that did not work. A local auto store could not help me. This one fixed the problem and worked perfect.

Pros: More than enough wiring and easy to install.

Cons: To bad I had to bypass the factory amp.

Installed in a 2006 Nissan Pathfinder to replace the BOSE Premium Sound Package. It is now far the better. Works flawlessly, was a pleasure to work with the Crutchfield team. Very easy to work with and installation was quite fast. Very glad to work with Crutchfield, and will do so in the future without a doubt.

Pros: Fluid communication without interruption.

Cons: None

The perfect work around the factory amplifier

Written By Doug, Bellingham, WA on Wednesday, April 09, 2014

Crutchfield Customer Review (What's this?)

I ordered an Alpine car stereo, 4 speakers, and dash mounting kit for my daughters 99 Ford Escort. Crutchfield sent me all the goodies to make the install as easy as could be. However, because my daughter had a tape stuck in the factory tape deck, I didn't see the label that said "Premium Sound." With the premium sound option, there is a power amplifier under the drivers seat. In order to install an after market stereo with speakers, you have to bypass this amp. This pig tail is all that is required. Unplug factory amp (two connections), plug in pig tail, and run the wires under the carpet and up to the new stereos speaker connections. That's it. Worked like a champ. The pig tail comes with about 10 feet of wire. Don't let that scare you. Just cut the wires up near the new stereo with a little extra length to play with and your done.

Pros: Crutchfield's tech support. These guys know their stuff. The pig tail adapter was exactly what I needed.

Cons: Nothing.

Fast and easy

Crutchfield Customer Review (What's this?)

I ended up using the Scosche CFDK6 factory integration kit when I realized I would have to run about 10 feet of wiring harness from the right rear of my Explorer (where the amp is) to the front of the car. Not being familiar with the install process, I thought nothing of it when Crutchfield offered me this "free" harness and the head unit I was installing already had amplified outputs. So I said, "sure, we'll bypass the amp". It would have been nice if my "advisor" had said "hey, you might want to re-think that and save yourself a few hours of work and aggravation and by this $15 integration module instead".

wrong wiring for my car

Written By Dylan, glendale utah on Sunday, March 09, 2014

Crutchfield Customer Review (What's this?)

I wish this would have worked. It was advertised to bypass my factory amplifiers. It did not the plug was right but it didn't work. I do not blame the product but're technicians that sent it. I finally bought a wiring harness that used the factory amp.

Pros: Nothing for me but the was plenty of length in the wires you can pit if anywhere in the car.

Cons: To many loose wires it needs to be taped before Install.

Pros: plenty of wire,plugs correct.good tech support

Cons: About half way down the harness,on the side with out a plug,the color code for the negitive /positive speaker wires was gone[.about the last 4 feet].I should have checked this before I completely installed it from the rear of the veihicle to the front.My bad.I pulled it back out til I picked up the color code,put my own mark on the ends,etc..problem solved.

Factory amp bypass harness

Written By Cody, Villa Park, IL on Friday, April 05, 2013

Crutchfield Customer Review (What's this?)

My application was a 1999 Ford Mustang with the standard audio system so I ended up cutting off all but a foot of the speaker harness. Otherwise it was very straight forward. I de-pined a couple of the wires that were not used like the blue remote turn-on lead on the speaker harness and one of the illumination wires on the main harness.

Pros: Fits, decent quality wire

Cons: Extra wire length - waste if you're not using it for your application

I am sure this is a fine wiring harness, but it did not fit my radio/truck, it was returned, the salespeople should have known, I had to get the proper wiring harness somehwere else.

makes it easy

Written By Jeff A, Wyoming on Sunday, March 17, 2013

Crutchfield Customer Review (What's this?)

This harness is a must for bypassing the factory amp. I ran this harness down the right side of the car in the factory wire chase and then up under the dash to the radio location. I even had to cut off about 2.5 feet of wire. I used it in a 97 Town Car and I can't think of any application that would require a longer harness. Once I decided to remove the rear seat the acutal running of the harness took about 20 minutes.

Pros: plenty of wire

Power and speaker harness.

Written By MikeM, Huntsville Texas on Sunday, December 30, 2012

Crutchfield Customer Review (What's this?)

The only part the worked snapped in right was the power connection. The only reason it gets a two instead of a one or less. The speaker/wire harness did not fit the connections for the amp bypass. So the only good that came out of it was I was able to use the wire to run it directly from the speakers to the radio. Lucky it was free wire.

Pros: Only the power wire harnees worked.

Cons: The speaker harness did not work, connections was useless. So had to cut the wires and run them directly. Which resulted in way more crawling around the belly of the vehicle then intended or expected with Crutchfield products I have used before.

just what i wanted

Pros: easy to install

Cons: no antenna extension


Written By Appleman, Plainsboro, NJ on Tuesday, May 22, 2012

Crutchfield Customer Review (What's this?)

Perfect for my application. Only gripe is that the wires are not sheathed. Whenever you run wire through a vehicle it shouldn't be just wires, they should be protected. Just enough wire. Had about 2 feet extra so I just coiled it behind the dash. Excellent instructions that anyone could follow. I found the remote lead to be slightly confusing, so I just hooked it up to the amp in the back because I didn't have a remote antenna.

Pros: long, labeled clearly, great condition/packaging.

Cons: exposed, confusing remote wires.

Receiver Wire harness

Written By Gary, Rhode Island on Friday, April 27, 2012

Crutchfield Customer Review (What's this?)

The harness was useless, I used power and ground on one harness ( no use for the other 6 ) and the second harness the connector did not match my existing so I had to cut the existing and butt splice it to my radio.

Pros: There were none.

Cons: The Crutchfield on line system that offers you an after market harness to match your vehicle is not very accurate, my harnesses were useless for installation.

Works Awesome

Written By CitySammy, NYC on Monday, April 02, 2012

Crutchfield Customer Review (What's this?)

Once you get to the amp, which is tucked way in the back qrt. panel, (97 Explorer), setting this up is pretty easy. I found that I couldn't get the antenna to work only using the speaker harness, so I disconnected it from the amp, and just ran it straight to the head unit. Otherwise the power harness and speaker harness work perfectly.

2000 Mustang, premium sound system. Unplugged the factory amp connector, plugged it into my Crutchfield harness, cut the wires a foot or less on the other side of the plug (since I didn't need most of the wire that was in the kit), wired other half of the harness for the power and ground, plug and play. AWESOME

Pros: good quality, much better than the cheapo harness adapters that were replaced with the old aftermarket cd player

This wiring harness was the key to making the installation very straightfoward. All I had to do was splice the corresponding wires from the radio using the documentation from the radio with the clearly defined and color coded wires on the harness.Everything worked perfectly the FIRST time!

Crutchfield Customer Review (What's this?)

The last one of these Town Cars I did, utilized a simple By-Pass Harness that just went right around the Factory Amp (in the trunk). The Amp appears to be the same as earlier models (NON JBL - Ford Amp). The By-Pass Harness I received this time, goes ALL THE WAY from the Head Unit to the TRUNK!!! I'm gonna' have to Rip This Car APART to do this job!! Not Very Happy with this change. Too much extra work, to do the same thing that a TWO-FOOT By-Pass did before!!

with Premium sound package. Make sure you have the proper clip removal tools and for
the back trim panel. Be careful to not push the top of the rear trim panel into the
headliner as to not tear it. The amp is located in the passenger rear under the back
window behind the trim panel. Pry off the trim along the passenger side of the car and
place the wire in the factory track under the trim. I had about 5 feet of extra wire so I
coiled and zip tied it together behind the passenger front kick panel. Plan on it taking
about 1 - 1.5 hours to disassemble the car, run the wire, solder the wire and heat shrink
tube, zip tie the wire in place, behind the glove box, and reinstall the panels that were

Not all harnesses are created equal...

Written By BrianC811, Huntsville, AL on Saturday, April 11, 2009

Crutchfield Customer Review (What's this?)

There is nothing wrong with this harness in and of itself. Directions are reasonably clear, and it can accomplish what you need. The thing that I would like to make Ford owners aware of is that I have had two Ford vehicles with factory upgraded stereos which means that Ford includes an amplifer in their system that when using this harness you would have to bypass. Most of the time this amplifier is located no where near the radio itself and you will have to take apart half of your car as well as reroute speaker cabling in order to do this. That is not very appealing to me and no matter how careful I am, things get broken and or are never reafixed as well as they originally were.

So in short while this is a good product, I want people to know that spending just a few more dollars for the amp integrating wiring harness instead of this one will save literally hours of install time, give you solderless connectors, and lessen the chance of damaging your vehicle on the install as everything will be located in the radio compartment.

The adapter fit. Took about an hour to run the wires from the rear amp to the head unit. Not as hard as I was expecting actually, just peel up the trim and follow the other wires in the wire tracks.

Crutchfield is the ONLY one to have this adapter!

Written By Hugh, Philly, PA on Wednesday, February 06, 2008

Crutchfield Customer Review (What's this?)

Here is the deal. On these cars there is an amp in the back of the vehicle. The harness you get is basically an amp bypass.
What you need to do is run a set of wires all the way from the head unit to the amp in the back of the vehicle.

Plan on spending an hour to run the wires.

Do not be misled by other companies. This is the adapter that you need. Crutchfield has done their homework!

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.
