About the Metra 70-1777 Receiver Wiring Harness

Metra 70-1777

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

Metra 70-1777

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. 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 (see Details for a list of connections) if you want your factory steering wheel audio controls to work with your new stereo.

Q
Will this work for the Audiophile 6 changer factory stereo with factory subwoofer in my 2003 Ford Focus zx3?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
