Metra 70-7003 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 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.

Installation Note: This harness uses your factory amplifier; your new stereo must have two pairs of preamp outputs to connect this harness.

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.

These cables were very useful, they made the wiring very simple & easy, plus, I was able to still use my stock infinity amp. with this radio, more power than I expected. they couldn't make easier unless they came out & did it for me. They are my only chose for upgrading stock radios ever...

Pros: simple, good directions, & phone help..5 stars guys..

great harness to integrate the factory amp

Written By Nick R, South hadley, ma on Thursday, April 02, 2015

Crutchfield Customer Review (What's this?)

This harness is great, depending on your head unit your wiring this to, make sure you read directions and it should be very easy. Once I wired it all up to my sony harness it was so easy to install it, just plug it in and your good.

Pros: This harness just has all the power wires, no speaker wires so wiring it up to a head unit should be easy cause you don't have to spend time with the speaker wires.

Cons: I did have to spend some time online to ensure j was wiring it up correctly.

Does what it says. I had numerous audio dealers tell me to just bypass the factory amp for an aftermarket head unit. About 15 min search at Crutchfield had the proper harness and amplifier integration hook up two days later. Easy button for sure.

plug and Play connection

Written By Mario_Audio_Head, Illinois on Sunday, February 08, 2015

Crutchfield Customer Review (What's this?)

Cables worked out of the box, due to car having oem amp, I had to use the RCA in to the deck and than it goes to stock amplifier that is in the car. Everything worked fine, no issues. Cables for power connections where super easy, everything worked out of the box. Cable instructions were easy and straight forward.

Pros: Very simple to connect and use. Worked out of a box.

Cons: Not a coin, but suggestion, wish the RCA's were color coded or at least provide witch one is front and back, right or left... other than that no complain.

Perfect for the Montero

Written By Linda, Lehigh Valley, PA on Tuesday, January 27, 2015

Crutchfield Customer Review (What's this?)

I got this so my son could install a new receiver in our 2003 Montero. He's very DIY, but was getting frustrated because he had three blue wires (one from the receiver, one from each harness in this package), and some sources said that connecting the wires a certain way would drain the battery. He got it figured out and everything works now, but he wishes that some instructions were included with the harness.

Pros: Just what we needed

Cons: No instructions, confusion with multiple wires of same color, bulky

Crutchfield response on Wednesday, January 28, 2015 Remember, as a Crutchfield customer, you get access to our Tech Support team, available 7-days a week, free for the life of the product. They're highly trained professionals, ready to answer questions and help solve problems like this. They can do everything from walk you through the installation to help you set the clock.

Written By Anonymous, Chicago, IL on Tuesday, October 07, 2014

Crutchfield Customer Review (What's this?)

Really happy with the Crutchfield service. I listed the stereo and the car and he was able to ship out the correct wiring harness at a great price. Best I found on the internet!! Easy to install with the direction that they shipped along free. Could not have been more happy. Installation took 35 min. and I have never installed a car stereo before. Saved me $100 that a large box store quoted me for installation of the stereo I purchased.

Pros: Customer Service, Free Shipping, Full Directions

Cons: I should have also bought the stereo here also, I would have save about $10 and a weeks worth of time looking for the wiring harness. Glad I found them eventually!

Great product to have

Written By pipes, Jamestown ny on Tuesday, August 05, 2014

Crutchfield Customer Review (What's this?)

Great product to have because it takes all the guess work out of having to worry about what speaker wires go where. Just plug it in and away you go.

Pros: Easy to use and to connect.

Cons: Just need to figure out which of the two RCA jacks go to which ports.

Metra 70-7003 Receiver Wiring Harness

Written By uraspaz88, North Canton, OH on Monday, May 12, 2014

Crutchfield Customer Review (What's this?)

Works as advertised. Made the hookup to my 2003 Mitsubishi Eclipse's stock infinity amp a breeze. Sound quality is just as good as before.

Pros: Ease of use

Cons: Instructions slightly confusing because they were written to cover multiple cars, most of which didn't have the stock infinity sound system that my car does. The labels for each wire were usually easy to comprehend, but the optional power control/amplifier turn on wires were confusing to me at first.

Just what I needed

Written By Daryl G, south TX on Thursday, May 08, 2014

Crutchfield Customer Review (What's this?)

Bought an aftermarket radio for my 2000 Mistubishi Galant GTZ with Infinity sound system and wasn't able to utilize the aftermarket harness I got elsewhere because of compatibility isses. Ordered this one from Crutchfield and it was a cake walk after that. Great product for a specific purpose.

Pros: Very easy to read instructions and very easy to install.

Wiring harness for JVC into 2002 Eclipse

Written By Todd T., East Wenatchee, WA on Saturday, April 06, 2013

Crutchfield Customer Review (What's this?)

The wiring harnesses worked perfectly. HIGHLY recommend purchasing them. NOTE: when purchasing a unit for the Eclipse, make sure the unit has both front AND rear out puts so that the stock amp my be utilized. Also as a bonus, I was aware that the stock radio display would no longer be functional however the clock is still there.

Pros: All's good

Cons: None

Written By NickM, Huntington Beach,Ca on Monday, March 18, 2013

Crutchfield Customer Review (What's this?)

Part connecting to rear of the unit was good. But speaker connections are another story. Had to cut and solder speaker wires . My factory stereo output has six output coaxial(something similar). Cructhfield wire harness offers only 4 speaker output. Looks like a crossover takes place somewhere. But the sound cannot be distinguished from separate speakers. The sound is clustered between two front and one rear speaker.Subwoofer sound sound is very minimal. I may have to take it to a professional installer.

Written By Greg B., Glen Burnie, MD on Thursday, December 29, 2011

Crutchfield Customer Review (What's this?)

This integration harness worked perfectly for me. I installed my Pioneer DEH3200UB into my 2001 Galant GTZ and used the harness to connect the Infinity amp which is driving the seven speakers to the headunit. I also have a 12" Infinity Reference subwoofer I wanted to use, so I got two RCA Y-cables (has one male connector on one end and two female connectors on the other) and split my front preouts to connect all four RCA's to the front signal and used the rear signal for the subwoofer, so this harness CAN be used with a subwoofer! Just set the HPF on the deck so the inside speakers play no bass, and you are set, as the aftermarket radio will allow the volume to go higher than the stock headunit. Beautiful sound quality.

This worked perfectly to be able to use the factory Infinity amp without cutting up the harness. Many forums cried about the factory systems being hard to put aftermarket stuff on but this harness made it simple. A+++

Had the Infinity system in my '95 GSX, and used this harness when replacing the deck. This was great, plugged right in, made my life really easy. I've had to do all the wires in the past and that sucks, so this made things really fast.

ok for the right situation

Written By matt, ATL, Georgia on Saturday, December 27, 2008

Crutchfield Customer Review (What's this?)

This connection works alright if you have the right stereo. If you want subs and your stereo doesnt have 6 outputs than this harness is useless. The speakers are hooked up to the RCA cables not the actual wire from the stereo. I tried cutting and attaching all sorts of connections but no matter what i did I either couldnt use my subs or I couldnt use my rear speakers. I didnt mind not using my rear speakers except they made a high pitch hum when not hooked up. If you dont want subs this makes the install really quick and easy. I had to return my stereo to crutchfeild so i could get one that has six outputs.

Not a BAD harness, BUT....

Written By Brian, Rockledge, FL on Saturday, October 11, 2008

Crutchfield Customer Review (What's this?)

Well...It does fit the stock radio harness. But I had to go buy RCA female connections and solder them into the replacement radio's harness, so I could more easily connect the amplifier adapter to the radio replacement harness. The alternative was to cut the RCA male ends off, and attemt to separate the positive from the negative. I think just putting RCA female ends on the Kenwood's harness was easier for me to keep track of. You definately need to know your way around an electrical schematic, both for the original radio harness in the car and the one coming with what ever radio you're replacing it with. It gets a bit confusing, especially if your replacement radio requires a ground (and most do) because the crutchfield adapter does not have a ground wire. You'll have to use the one from your replacement radio harness. After I soldered the three harnesses together (the two from crutchfield and the one from the radio) it looked like a mess, but it worked fine.

Everything worked like a charm until I got to the wiring harness. I hooked it up but I had no power. After 1/2 hour of using my circuit tester I found that one of the wires in the harness was in the wrong slot. I removed the wire and moved it over and everything worked fine. Kind of annoying!

Horrible 'adapter'

Written By Butch, Corpus Christi, TX on Monday, October 06, 2008

Crutchfield Customer Review (What's this?)

I've used Crutchfield install kits twice before and loved them. Made life easy. This time it was horrible. Its not a direct adapter to the harness, I still had to cut the speaker wires out of the stock harness and connect them to the Crutchfield adapter. The adapter only actually connects four wires of the whole bundle, the other 12 are speaker wires that I have to splice. Not to mention the fact Crutchfield doesn't have an install manual for my series of car (Mitsu 3000GT '91-99). And the kit came with the radio adapter, an amp adapter (which is actually nice and easy) and another adapter that attached to the stock harness, which like I said, is worthless as it only actually connects 4 of the 16 wires. Not happy with the kit.

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.
