Metra 70-7302 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. You can also call an Advisor for more information.

Metra 70-7302 Receiver Wiring Harness

Crutchfield Customer Review (What's this?)

Great little harness, colors match up with factory wiring. Perfect, snug fit into receiver socket.

Pros: Precut insulation helped with stripping, color coded wire matched factory.

Cons: None

Crutchfield Customer Review (What's this?)

Works as advertised. I soldered my connections.

Pros: All wires matched exactly with my stereo and existing car harness

Cons: Wires #11 & 12 for instance on my car should have been included in this harness to fully integrate the Axxess AWSC-1 wiring outside the car. This would make for much easier and improved wiring overall for the new stereo. I had to clip to wires on the car wiring and tie to other wires in a very tight spot. Adding these two wires even if you cut or tape of as unused would be light years ahead on ease of installation.

Crutchfield Customer Review (What's this?)

This wire-harness fit perfectly with our 2008 Santa Fe. The only thing I would like to see would be some additional pin-out connectors to make connecting some of the adapters easier so I didn't have to splice wires on the factory side of the adapter.

Pros: Fit great

Cons: None really

Easy Install

This harness was great! All of the connections can be conveniently made out side of the vehicle, and it connected to the vehicle harness perfectly.

Product Research


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.
