About the Metra 70-5006 Receiver Wiring Harness

Metra 70-5006 Receiver Wiring Harness

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

Metra 70-5006 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:

Note: Two speaker harnesses are included — one is used if you have a factory amplifier, one is used if you don't. If there is no ground wire in the factory harness, you'll need to make a ground connection between your new receiver and your car's metal chassis.

Works great for factory amp bypass on Fox body Mustang. I will say that the instrument lighting did take some figuring out. I had to consult a wiring diagram and found I had to disconnect and jump two wires at the day/night relay to get an on off voltage

Pros: Plugs right in

Cons: Figuring out the dimmer function but not a big deal

Ended up not using it, the one plug did connect to the car but did not work. Had to cut the one that was there and splice the new head unit in. Odd enough it was just as easy.

Pros: Good solid connectors and look to be well made.

Cons: Didn't work, and not really needed.

A NO BRAINER!!!

Verified employee purchase (What's this?)

Good luck putting a radio in a 1990 FORD without this wiring harness! It's just not going to happen without way too much frustration. These things make upgrading a BREEZE. If you can connect two wires together and follow simple color-code directions, this is about all the expertise you're going to need to upgrade your system! Seriously. I have 20 years electrical of background, and I would not install a stereo or head unit with out these. For the price, it's a steal. Do it right the FIRST time, and get the RIGHT harness for the job!! It took me about 30 minute TOTAL to install my stereo... and here's the coolest part: since this connects to the BACK of your radio.. you can connect the harness together in the comfort of your garage, workshop, or kitchen table, and NOT have to be in some crazy position in the car trying to connect it all up!!! No cutting and scraping up your arms on the opening!!! (I had to modify my dash for the receiver I bought). Then, walk to the car, hook it up, test it out, and when it works THE FIRST TIME.... assemble it all.... minus the headache!!

Pros: Makes you a PRO at upgrading your FORD system. Do it in about 1/10 the normal time.

Cons: It could be free... just sayin.

Harness worked great. This is my third time installing a receiver in my vehicle with Crutchfield's great products. Instructions are pretty easy to follow and I saved $150 by not having it done at a shop. The technical support is first rate and very helpful.

Pros: Everything was set up for an idiot like myself to just hook together by following the instructions. Couldn't be nicer.

Cons: None

Receiver Wire Harness

John C from Suwanee, GA on 1/2/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

The wiring harness for power was straight forward and instructions were clear. The speaker wire harness directions were not as clear when working with my older (90) Mustangs premium sound system, which required me to use a third harness and connect diretly to the amplifier in the car. Crutchfield was very helpful in directing me to the proper requirement, although getting to the wiring harness on the amplifier was somewhat difficult.

Pros: harnesses fit well with my older model mustangs existing harnesses.

Cons: The instructions were not as clear for the speaker connection harness. I initially used the harness that matched up to the old radio harness, which kept shorting out, before contacting Crutchfield and realizing I had to use the third harness provided and connect directly to the amplifier in the car. Everything worked fine after that.

Receiver Wire Harness

John C. from Minneapolis on 7/24/2013

1990 Ford Mustang

Verified customer (What's this?)
Verified employee purchase (What's this?)

Item installation was poorly described, had to rewire it from scratch because my car had a factory amp in addition to the radio. I'd gladly pay a few bucks more and have a product that contains a set of alternative wiring harnesses that are each pre-wired at both ends so I don't have to solder them. Just pick the right harness and plug and play at both ends. As is, this seems like antiquated technology.

Product Research

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.
