Metra 70-1693 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. 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.

Crutchfield Customer Review (What's this?)

This seems to be a well designed product and I think it would have made the install easier. However my older car no longer has the standard wiring that would allow use of the product. This rating reflects the fact that I should have been directed to not purchase the item at all. Crutchfield gladly and quickly refunded my money which I really appreciate.



Free with purchase

Crutchfield Customer Review (What's this?)

These came with my radio purchase, but are 1 of several connectors required. The other connectors are NOT supplied or available for purchase. What is the point of using these connectors if you have to cut the wiring harness to connect the remaining wires? It would be much better if Crutchfield would make available ALL the connectors required for a complete installation.

Pros: Well made , works as expected.

Cons: I was not able to use them because I could not buy the rest of the required connectors.

Would work perfectly

Excellent option if you are keeping your current speaker connections. I didn't need it but it was sent free by Crutchfield anyway.

Pros: Good adapter

Cons: None

This made installation in my 91 318is incredibly simple.



Simple installation

Crutchfield Customer Review (What's this?)

I have a 1991 BMW 318is and used these speaker connectors since it came with the order. It was easy to use and install, straightforward, and nothing to hate about them. I guess the alternative to these things is just to crimp the speaker wires together.




Hands-on research

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 and sold separately.
