Metra 70-9221 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.

Connections:

Note: This harness doesn't include connections for illumination or dimming, so you may need to make those connections manually, depending on your new receiver.

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.

Volvo Receiver Wire Harness

Written By Anonymous, Oregon on Saturday, May 04, 2013

Crutchfield Customer Review (What's this?)

This harness works great! I was able to soldier the converter harness to the aftermarket stereo harness and make a flawless easy to connect and disconnect plug to the stock Volvo stereo harness. Now if I need to remove my stereo for any reason, all I have to do is unplug it instead of having to cut the wires and destroy the stock harness.

Pros: Easy connections, Able to soldier wires,

Tight Fit.

Written By John, Omaha, NE on Sunday, April 28, 2013

Crutchfield Customer Review (What's this?)

Too big to fit behind the radio....but I made it fit. Also, the remote wire didn't work to the subs, so I had to hook it up to the constant power....annoying but not to big a deal.

Pros: Good price

Cons: Way too big.

Would not fit in my Volvo S60

Written By FrankG, Blacksburg, VA on Tuesday, April 16, 2013

Crutchfield Customer Review (What's this?)

I was not able to use this harness. My 2007 Volvo S60 had way too little room behind the radio compartment to fit the large connectors. I ended having to cut all the connectors out (both the OEM and the harness connectors) and solder all the connections. Even then it was a tight fit!

Pros: It (would have) made the installation easy.

Cons: Would not fit in the space Volvo allocated between the radio compartment and the bulkhead.

Volvo S40 requires additional harness

Written By ChrisW, Midwest on Friday, December 14, 2012

This harness is necessary for the HU power, ground, ect. but you will need an additional harness for the factory amp interface found in the 99-03 Volvo S40's. Without this additional harness, only the dash tweeters will work. The alternative is bypassing the factory amp and running new speaker wire in a (slightly over-engineered) Volvo. Huge pain. You could cut the interface plug open and test wires untill you have sound in all four doors. Huge pain.

Pros: It does fit and works fine. It is the power, ground, remote and dash tweeters.

Cons: I wish I had known I would have to scour the web for the wierd extra harness for the door speakers to work. The factory amp interface is a strange cd changer -esque looking thing that is very difficult to find any kind of wiring diagram for. If you have a whole day to kill, bypassing the factory amp and running new speaker wire to the HU would work. The extra harness is much faster and a cleaner install overall in my opinion.

Antenna adapter

Written By Patrick, USA on Thursday, August 09, 2012

Crutchfield Customer Review (What's this?)

It worked.

Pros: Easily adapts from Volvo antenna to JVC radio.

Cons: The plug that fits into the radio seemed a very little bit too small, so the fit wasn't as tight as I'd like. As I installed it I was wondering if would eventually vibrate loose. It was not bad, just not a perfect fit.

Does not Work with S40's

Written By Anonymous, Texas on Friday, November 06, 2009

When I first got the only two speakers in my car worked. Found out that s40's come with an Factory amp. I Bought an adaptor. All is well, but beware and save your self head aches, s40 until 03 i believe come standard with an amp. Fyi,

Thumbs up

Written By Chris, Littleton, CO on Sunday, April 26, 2009

Crutchfield Customer Review (What's this?)

Worked great in my '01 V70, no issues. I picked up an extra stereo frame from a junkyard, so I was able to install the stereo into the dash adapter and wire it on the bench, and did the stereo swap in about 5 minutes.
