Metra 70-5001 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.

Connections:

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

Features

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.

1986 F250 kit

Written By tkmfarm, McMinnville, Oregon on Wednesday, August 06, 2014

Crutchfield Customer Review (What's this?)

The wiring is backwards. Front wires on the kit go to empty spaces on the OEM plug, the rear wires on the kit go to the front wires on the OEM plug.

Pros: The plug fit.

Cons: Wires are backwards.

Metra 70-5001 Receiver Wiring Harness

Written By JasonH, Dallas, TX on Sunday, February 13, 2011

Crutchfield Customer Review (What's this?)

The wiring diagrams are included and the harness works like a charm. Be mindful
that you WILL need to run the ground wire to a solid ground location inside the
car (I just ran it to one of the screws that holds the mounting plate to the car
since that's a good metal ground). This will also eliminate the premium sound
if equipped (but it's not needed since the old amp puts out a little less power
than modern head units).
