Metra 70-7554 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.

Crutchfield Customer Review (What's this?)

If you are expected a full set of wires to fit the full set in the car... don't. To be fair the product picture shows that it only has four wires and that's exactly what it has. It has exactly enough wires to make the deck function. What it doesn't have are the steering wheel control wires, back-up camera wires, reverse indicator wires or any other accessory wires necessary. You will have to sort that out yourself. And if you have the same luck as me, finding diagrams for my 2012 Altima has been very difficult. The Crutchfield support folks have been very helpful, as usual, with information as they have it. But I do wish this harness had all the connections instead of power and ground wires only.

Pros: works

Cons: missing all accessory wires and only has the essential power and ground wires

Preliminary info from the manufacturer

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.

Factory Amp Note: This harness includes RCA connections (instead of speaker wire leads) to connect the aftermarket head unit's preamp outputs to your vehicle's factory amp. Your aftermarket head unit must be equipped with front & rear preamp outputs.

Ground Wire Note: No ground wire is present in harness. Connect the ground wire of your aftermarket head unit to the vehicle's metal chassis.
