Metra 70-2102 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.

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.

It worked

Written By A L, Detroit, MI on Saturday, March 22, 2014
Crutchfield Customer Review (What's this?)
 
It had every wire I needed. The wires were a thicker gauge than the harness on the radio I bought, so they should be more than capable of handling any loads they'll ever see.
Pros:
Good wire Fits well
Cons:
None

Metra 70-2102 Receiver Wiring Harness

Written By MarionM, Kansas City, MO on Monday, April 15, 2013
Crutchfield Customer Review (What's this?)
 
Wiring harness worked like a charm. There were a couple of extra wires that I did not need for my particular installation, that I was a bit nervous about, but a quick call to the Crutchfield help line cleared everything up and they were absolutely correct. I would also recommend the Posix connectors to anyone connecting one of these harnesses to your aftermarket stereo. They made good solid connections while taking up little space.

doesn't get any easier than this

Crutchfield Customer Review (What's this?)
 
not only does this harness fit properly, but the wire colors were an exact match for the JVC adapter on the head unit. easiest install I've ever done. protip: splice the harnesses together before plugging them in. that way you're not trying to splice wires in the dash.
Pros:
perfect fit, colors match
Cons:
none

Winner, winner, chicken dinner.

worked like a charm.

However, I had to hook up the external amp wire. I guess because my Ion has a 6 speaker system, it has an external amp. The tech help line gave me the info and i had it running in 2 minutes.

kudos to the help line.

Review for a wire harness?

Hah, a review for a wire harness seems comical, but this wire harness was definitely champion material for my '05 ION 2. And by champion material I mean that it was easy to hook up and it works.
