Metra 70-7712 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.

Isuzu Rodeo Wire Harness

Written By F. Turner, Carrollton, GA on Friday, December 14, 2012

Crutchfield Customer Review (What's this?)

Worked perfectly. The connector attaches in place of the factory radio. The flying leads on the harness are then attached to the new radio harness. I was able to make up the connections prior to installing the radio which reduced my actual installation time drastically. Well worth the money.

Pros: Plugged in to the existing car wiring perfectly.

Cons: none

Install in 2000 Isuzu Rodeo

Written By RPD, Chula Vista, CA on Friday, February 10, 2012

Crutchfield Customer Review (What's this?)

Perfect! All wires were color for color with the harness in the Clarion CX501. Took about 15 minutes to make the connections.

Crutchfield Customer Review (What's this?)

Very simple hookup (I had the factory pinout diagram in case of trouble, but didn't need
it). Crutchfield really makes it easy!

Good adapter

Written By Mike M., Richmiond, VA on Thursday, November 11, 2010

The adapter worked fine. The tool they use to strip the insulation from the wires cuts into the
copper so you end up having to cut off the ends and re strip the wires.

Other than that it worked fine.

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.
