Metra 70-7902 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.

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.

Without connector, the install would have been a nightmare. Wire leads are plenty long enough, made install easy!!

Crutchfield Customer Review (What's this?)

These harnesses are hard to find in Albuquerque and it was nice that it came
with my order, even though I didn't end up using the Mp345U head unit I ordered.
This harness is color coded and very easy to wire to the cars harness. Great

You'd be Crazy not to buy one

Written By David, Olympia WA on Thursday, January 28, 2010

Crutchfield Customer Review (What's this?)

This makes the installation a breeze. Once the old deck was out it took me about 5 minutes tops to install and test my new deck. Total removal & install time was about 20 minutes That includes splicing in the harness on the bench.
The availlability of this harness was the deciding factor berween me buying my deck at a local store or through Crutchfeild.

Crutchfield Customer Review (What's this?)

I highly recommend geting the installation instructions and wiring harness. It makes it a snap to install and if you splice it in to the existing, should you ever decide to change back to the original, say if you decide to sell the car and don't want to give up the new receiver you can cut off the new harness and take it with you.
