Metra 70-1003 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.

Connections:

  • 12V constant power
  • 12V switched power
  • chassis ground
  • power antenna turn-on
  • illumination
  • left front speakers +/-
  • right front speakers +/-
  • left rear speakers +/-
  • right rear speakers +/-

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

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.

Kia Receiver Wire Harness Reviews

Written By benderb9, St Petersburg, FL on Monday, March 31, 2014
Crutchfield Customer Review (What's this?)
 
Soldered and heat shrunk it up to my JVC's wiring harness at the kitchen table.Matching it up to the included diagram's made it a breeze. Simple plug-in and it was all over. Couldn't have been easier for my 2001 Kia Sportage.
Pros:
Allows easy wiring and can be done outside of the vehicle. Well made plug.
Cons:
None

Why Was I Worried?

Written By Mike, Indiana on Saturday, September 01, 2012
Crutchfield Customer Review (What's this?)
 
I never installed a car stereo before. And I bought a very nice replacement stereo, dash kit, and wiring harness from these people. The price and shipping were fantastic. But I was really worried about this part, the wiring harness. The instructions, diagram, and one phone call to the Tech Support that took about 2 minutes to get the help I needed, and this was a breeze. Any average person could follow the diagram, and do this. I turned the key and she lit up and sounded great. First time installing, what was I worried about? Now I need speakers to replace the factory tissue paper ones I have, and you can bet the farm they're being purchased right here!
Pros:
Simple as pie. First time installer, and flew right through it. The diagram and instruction sheet are "idiot proof"!
Cons:
Cons? Are you kidding? This could not be any easier, no way to find any "cons" in this sort of quality!

It only took about 5 minutes to connect this harness to the receiver. Excellent instructions as always from Crutchfield. Would not buy from anyone else!
