Metra 70-1741 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.


Note: You'll need to make a ground connection between your new receiver and your car's metal chassis.

Perfect, saved me from hacking up stock hareness

David from New Castle, DE on 9/12/2017

1989 Nissan 300ZX
Crutchfield Customer Review (What's this?)

Worked perfect on my 1989 300ZX GL with the amp under the passenger seat. The one line let's you bypass the amp without having to hack up the wiring.

Pros: Perfect fit, length, function


Don't Work for '86 300ZX

1986 Nissan 300ZX
Crutchfield Customer Review (What's this?)

These actually don't fit to the plugs on my car. I had to hard wire everything. Luckily these came free.

Pros: Free

Cons: Useless

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.

No Ground Wire: The wiring harness does not included a ground wire. You will need to make a ground connection directly between your aftermarket head unit and your vehicle's metal chassis.

Speaker Wire Harness Location: The speaker harness connection is located under the vehicle's passenger seat. You will need to run this 54" harness up to your in-dash aftermarket head unit.
