About the Metra 70-2003 Receiver Wiring Harness

Metra 70-2003 Receiver Wiring Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

Metra 70-2003 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 makes installing your new stereo easier, and allows you to put the factory radio back when you sell your vehicle or return it at the end of the lease. 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:

  • 12V constant power
  • 12V switched power
  • chassis ground
  • illumination
  • dimmer
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-

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 and sold separately.

3 questions already asked

Q
Is the wiring adapter I'm looking to purchase for my wife's '05 Pontiac Vibe going to tie into the OEM Monsoon audio system? I ask as this car obviously has at least a sub-woofer amplifier, likely more as it is pretty healthy for a factory stereo. I only ask as I despise having a dash apart only to find out IO don't have everything I need to continue. Thanks!

I'm sorry but I don't know.
[ RICH  Jul 10, 2018 ]
A
It is comparable to the monsoon system. You will not hook up the 2nd factory plug. I belI've there is a bus wire on the adapter that needs to be attached. I think the installation manual has those details.
[ Richard  Jul 06, 2018 ]
Q
Do you need a specific aftermarket wiring harness for a 2006 Kia Sorento ES with a factory amplifier?
[ GaryH  Feb 18, 2016 ]

A
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
