Metra 70-7304 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.

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, then check here for a list of parts. You can also call an Advisor for more information.

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.

Do your homework BEFORE calling Crutchfield

Written By Laura, Fort Wayne, IN on Tuesday, June 24, 2014
 
This is less about the product and more about customer service. I have a 2013 Hyundai Veloster and the website said it was for my car - but it's now been updated after my issue to show that it's not for my car. I called Crutchfield and was reassured this is the correct harness. So, I ordered it. I've installed all my own stereos in the past but the local guys implied that my vehicle could be slightly difficult. But, the product advisor insisted it's not. Well, I made my connections, double and triple checked my work then installed the stereo. Hmm....sound is off. Unable to fade to the back speakers. Uninstalled and checked everything again....Nope....sound still off. Called into Crutchfield, next person assured me again that this is the right harness and suggested something is wrong with the stereo. I was able to get my hands on another Sony and tried again. Same problem. Now I know it's the harness. Bought another one from somewhere else - same sound issues. After a week of troubleshooting and trying other options, I called Crutchfield again and explained everything. I was transferred to RJ who put me on hold while he searched for answers. He came back with some good info and confirmed it with Metra - this is the WRONG harness. The right one IS $150. But, There may be an alternate way of wiring this harness to work with my system. I'll know this week. If everything works, RJ is my hero. Crutchfield has since updated their website.
Pros:
Low price. Should be simple if it's the right harness for your car. RJ is the example of excellence the rest of Crutchfield's advisors should follow. He should get a bonus or an extra paid day off for going overboard on my issue.
Cons:
Crutchfield didn't do their homework before listing this as the harness for 2013 Hyundai Veloster (and I'm sure a few other models). They've since corrected their mistake but only after almost two weeks of my failure after they assured and reassured me this was the correct part. Now I'll question if they know what they're talking about if I ever need help again. Maybe I'll be able to contact RJ directly if I need to.

Workable

Written By Anonymous, Flower Mound, Texas on Monday, July 01, 2013
Crutchfield Customer Review (What's this?)
 
I liked how all the colors matched and it made my life a lot easier than trying to do it without a harness.
Pros:
It worked... mostly
Cons:
The black wire that was labeled to the steering wheel harness was in the wrong spot. I had to jump to negative to get it to work. It wasn't a big deal but it was an hour of troubleshooting that I'll never get back.

Wirin Harness for 2012 Kia soul

Written By Walt, Tampa, FL on Wednesday, July 11, 2012
Crutchfield Customer Review (What's this?)
 
This does fit the Kia Soul for the 2.0 L non Evo cars. It also move with the wiring for the speed sensor and the wire for the steering wheel controls. I personally needed 3 of these harnesses and pulled the pins out of 2 of them to integrate the factory kia USB Aux input and Microphone inputs so I didn't void my electrical warranty.
Pros:
Quality harness, fits tfactory plug correctly and all of the wire ae in the correct place.
Cons:
None.
