About the Metra 70-1822 Receiver Wiring Harness

Metra 70-1822 Receiver Wiring Harness

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

Metra 70-1822 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
  • power antenna turn-on
  • dimmer
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-
  • right rear speaker +/-

Metra 70-1822 Receiver Wiring Harness

Crutchfield customer from Des Plaines, IL on 4/18/2019

1986 Porsche 944

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

The wiring on the Adapter plug was not correct. The 12 volt power constant power tab was one port over from where it should have been. After confirming this with a wiring diagram and voltage meter I moved the port over. Would have been better if the assembly was wired correctly to make it plug and play as advertised.

Pros: Fit original harness but....

Cons: Not wired correctly

Nice concept. Nice execution. Even nicer that it was thrown in with my head unit. BUT pinout was incorrect for my vehicle. Listed 1986 Porsche 944 as compatible. It is sort of, after rearranging the pins.

Nicely built, but did not fit my 1994 Porsche 968 as expected it would after reading about stereo installations in that particular car. Was not able to use.

Pros: nicely built, not expensive

I didn't end up using them because the previous owner deleted the need for them with the last stereo install. I did inspect them for quality and they are very well made. They came free with my stereo.

Pros: Appear well made. Free!

Cons: None

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

This harness made it very easy to connect the new Kenwood receiver to my 1986 Porsche 944's speakers. The wires are clearly marked and color-coded, and plugged right into the existing harness in the car.

Pros: Labeled and color-coded wires make it easy to use

Cons: None

Great stereo, good quality, low boot up time, I only wish it would display the song info over Bluetooth, it only says my phone's name

Pros: Good functionality, sd I'd a nice alternative to a CD player

Cons: Lcd panel is bright and the cops stare me down as I drive by.

Just one issue

Stephen from Greensboro, NC on 3/14/2015

1986 Porsche 944

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

The connectors allow the car to remain stock. The single issue was pin location. One of the pins did not match the car. It was easily fixed by using a paper clip wire to release the pin from the connector body and relocating it to the correct location

Pros: No cutting or splicing of original car harness

Cons:

Wiring harness

Jake from Omaha, NE on 9/16/2014

1988 Porsche 924S

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

I recently had to replace the stereo head in my Porsche. It amazed me that Crutchfields would have a harness that had exactly the same connectors that were in the car! The entire process took about 45 minutes, mostly soldering the new adapter to the harness that came with the head, and the system worked perfectly. I am so pleased, the cost was minimal, and the instructions were excellent. I would never have thought they would have a harness for a 26 year old Porsche, but they did, and it's great!

Pros: Order help Perfect fit and adaptability Easy to follow instructions

Cons: None

Perfect match to existing 1987 Porsche 944 harness. I was amazed. No place to make a mistake, and no cutting of the old wiring. Snap it in, turn it on, hear music.

Pros: Obviously engineered to do what it is supposed to, and does it well.

Cons: None

This is the perfect bridge between the old style and the new style Balupunkt units. Don't try to replace your radio without this.

Pros: Keeps all parts intact, so no cutting of wires is required.

Cons: Very few

Swapping out the factory installed headunit and amp was made simple with this kit. The only modification I needed to make was to file flat the areas where the speaker connectors back up to one another to allow a good fit.

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.
