Metra 70-7992 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.

2002 Suzuki XL-7
Crutchfield Customer Review (What's this?)

This worked well with one problem. The connector for the ground wire was the wrong gender to plug into the coonnector from my 2002 XL7. I just cut the supplied connector off the kit and spliced on the connector from the old radio and it plugged in and worked fine!



2001 Suzuki XL-7 Installation

2001 Suzuki XL-7
Crutchfield Customer Review (What's this?)

I had a bit of trouble with this at first because it was too small to fit the factory installed harness. Called the Crutchfield technical support line and after about a minute, the technician clarified the situation. Seems on the 2001 XL-7, the harness you had attached to the factory installed radio is actually a pigtail harness. The primary harness was hidden underneath the foam covering. Once this was explained to me, the installation went ahead with only a problem being with the supplied ground lead. The connector supplied is the same size as the factory installed one (didn't see any foam this time) so I just cut the mounting lug off and soldered it to the ground connection on the new radio's harness and it worked fine. A lot easier then trying to cut and solder the old harness onto the new radio harness!

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.
