Metra 70-1776 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.

Metra 70-1776 Wiring Harness

Crutchfield customer from Auburn, CA on 1/9/2017

2003 Ford Expedition

Verified customer (What's this?)
Verified employee purchase (What's this?)

This set of connectors was great except for the rear seat entertainment harness. It did plug together and appeared to be correct but the wires from the vehicle harness were on the opposite row of pins from the aftermarket one. It was not possible to put it together backwards so I had to cut and splice the wires one at a time. There were only 2 I needed, the reverse and steering wheel controls. I was not able to remove the pins and insert them in the proper place on mating connector.

Pros: Would be great if it were wired correctly.

Cons: Not wired correctly for my car.

Based on the recommendation of your customer service this was purchased for my 05 Ford Expedition with navigation. We needed the dvd player and all other items to work. Well, the back controls for volume and other items do not work. Very disappointing, we also called your technical support and went through each line step by step, and still the volume and controls due not work. He just kept saying, "well it should". Well it does not. He had no answers. I spent good money to solve a problem instead it created another problem. Very upsetting to the wife.

Pros:

Cons:

Crutchfield response on 12/13/2016
Once we saw this review, our Tech Support team reached out to Hania to issue an apology and help him further. We'll either help him get the harness working the way it should, or help him return it for an exchange or refund.
