Metra 70-5000 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: You'll need to make a ground connection between your new receiver and your car's metal chassis. The package you receive will include two sets of wiring harnesses. Select and use the pair that matches your vehicle's harnesses.

  • 12V switched power

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 is so easy to install that my 17 year old son did his own stereo install. Just match the colors for the radio and you're good to go. Perfect fit to OEM harness.

Pros: Perfect fit to OEM harness Easy to use Ends cut for correct strip length

Wiring Harness

Written By George, Chesapeake, VA on Monday, October 01, 2012

Crutchfield Customer Review (What's this?)

The wiring harness was useless to me. It was simply the wrong one. It would have taken me more time to use the supplied harness than it took me to use the existing after market harness I had been using previously.

Pros: none

Cons: I didn't even try and use this harness. It would not connect to the original wiring for my 1998 Ford F-150.

Got the job done

Written By Anonymous, Cookeville, TN on Tuesday, October 04, 2011

Crutchfield Customer Review (What's this?)

Be careful if you're using crimp connectors the wire is soft, I had a problem with the wire smashing in two. Other than that I didn't have any problems.

Metra 70-5000 Receiver Wiring Harness

Written By DanR, Tacoma,Wa on Thursday, May 12, 2011

Crutchfield Customer Review (What's this?)

The harness is a nice plug in option to splicing but, at-least for my "88" F-150 the
diagram was wrong so it's best to ohm the speaker wires from your door to the
harness to find the positive and negative for each speaker and relabel the diagram
before you make the final connections.

Excellent adapter

Written By Robert, Dothan, Al on Thursday, April 09, 2009

Crutchfield Customer Review (What's this?)

This wiring harness worked very well with the new radio. I had no problems wiring this harness to the new radio harness. The color scheme was straight forward. The hard part was verifying my Ford wiring harness to match up to the adapter harness. My schematic in my Haynes manual did not match the color scheme in the factor harness and the ground wire shown was not installed. Once verified, it was easy to install the ground. Straight forward plug and play after that. The install took about an hour.

Worked

Written By Vic, Trenton, NJ on Thursday, January 29, 2009

Crutchfield Customer Review (What's this?)

Worked fine but I did have to confirm its application with Crutchfield Rep. Install was easy and quick. It was important to confirm the power hook up. I had to not use one wire and connect another to my fuse panel as an on/off switch for the reciver.

It worked.

Written By derek, Tigerton,WI. on Monday, September 18, 2006

Make sure you get a good ground, don't blame the harness. But everything else is strip, shrink, and plug and play, really loud.

great
