Metra 70-1782 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
  • illumination
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-
  • right rear speaker +/-

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 and sold separately.

DOESNT FIT 99 SUZUKI VITARA

Written By Kevin, Holland, PA on Wednesday, April 30, 2014
 
I bought this product to make wiring my head unit in my 1999 Suzuki Vitara much easier, however, it doesn't fit. Even though Crutchfield says it does, it was a waste of money.
Pros:
none
Cons:

Made wiring easy

Crutchfield Customer Review (What's this?)
 
Was impressed with harness & detailed instructions. The wiring intimidated me at first, but your diagram made it easy to understand. It put the 'cookies on the bottom shelf' so I could reach them. I will buy the dash kit from yall also.
Pros:
Easy to understand
Cons:
None

Great wiring harness!

Written By BrianW, Franklin, TN on Monday, July 16, 2012
Crutchfield Customer Review (What's this?)
 
Easy to use and comes with a clearly labeled wiring diagram. This is the first install I've done in 20 years, and it made it a lot easier being able to wire the harness to the stereo before beginning the actual installation. Definitely recommend!
Pros:
Good quality connector. Clear instructions and wiring diagram. Keeps the car's wiring harness intact.
Cons:
None.

Orange/ white dimmer wire missing from this harness

Written By Jeff, Emmaus, PA. on Friday, September 23, 2011
Crutchfield Customer Review (What's this?)
 
Fits nice, ample size leads to work with. Only thing is the wire for dimming lights that is on the factory harness is not on this one. Not really needed in most applications anyway, just thought it was noteworthy.

Huge help

Written By Bob, Newport News, VA on Sunday, March 13, 2011
Crutchfield Customer Review (What's this?)
 
This harness and directions were a huge help in preparing my receiver for
installation. There was almost a one-to-one correspondence with the receiver's
wires and once it was hooked up it snapped into my vehicle's plug. Thanks

Good Harness

Written By Marc, Cape Coral, FL on Friday, May 15, 2009
Crutchfield Customer Review (What's this?)
 
This harness made wiring in my stereo incredibly easy, and it fit perfectly. The factory connector was a perfect match. The harness on my new stereo unplugs from the head unit, so it was simple to wire the two harnesses together completely out of the car, then just plug them both into their matching recepticles. The only difficulty I had was telling the green wires from the gray wires on this harness. I'm a tad color blind, and these two wire colors looked a lot alike at first. The wires on the stereo harness were much more clearly green and gray. That was just a minor problem, though it could have lead to a lot of headaches later.

Wire harness

Written By Chris, Brandon, VT on Friday, February 06, 2009
Crutchfield Customer Review (What's this?)
 
The harness is a great fit. I wish that Crutchfield would look into getting harnesses that would have a universal 16 pin (2x8) harness at the opposite end of the vehicle harness, that would really sweeten the deal. I take the time to add insulated female clips to each wire so if I need to take out the stereo for any reason I don't need to cut any wires, and I can add a different stereo with ease if I want. It take a bit of time, but in my opinion it's worth it. As always nothing but great service from Crutchfield!!

Just like OEM

Written By Brad, Salem, UT on Monday, January 26, 2009
Crutchfield Customer Review (What's this?)
 
We ended up not needing this connector because of the previous installation cut the wires.

BUT! This is the same connector I used on my Toyota Celica installation and with the wires that are very similar to the wires on the aftermarket radio harness it makes wiring a breeze. I solder all my wires for a more reliable connection but still tend to use black tape as an insulator (to protect against shorting out the wires on ground).

Ease of wire colors and simple to read instructions give this product 5 stars.
