About the Metra 70-1782 Receiver Wiring Harness

Metra 70-1782 receiver wiring harness

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

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 +/-

I've done radios without a harness, but this made it so easy. I had the radio wired up and ready to go before I started removing the old one. Just plugged it into my factory radio plug, slid it in and it worked perfectly.

Pros: Works perfectly FREE

Cons: None. It's a fabulous product.

Great product that Crutchfield gives you for free

Romeo from Orange Park, FL on 7/10/2017

1992 Geo Tracker

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

Although this is free from Crutchfield, it makes installing your CD player a very easy "plug-n-play" job. You pretty much just match the colors, red to red, black to black, yellow to yellow (these are for power). The rest are for speakers (gray, white, green and purple). The only thing, is just make sure you set the positive with the positive, and negative with the negative (negative has a black stripe). Other than that, it's pretty easy. Also, makes it that you don't have to cut any of your factory wiring harness.

Pros: it's free, and makes hooking up a head unit a BREEEEEEZE

Cons: Nothing really.. It's free....

Verified employee purchase (What's this?)

Bought it because of tech support. Didn't need it. Diagrams were easy to follow. Pretty idiot proof...just connect coded wire to the wire of the same code. No duplicate colors and nearly impossible to mess up. Just use good butt connectors and make sure the a closed tight.

Pros: Color coded wires

Cons: Increase price and include butt connectors

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

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.

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.

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.

Good Harness

Marc from Cape Coral, FL on 5/15/2009

1993 Geo Metro

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

Chris from Brandon, VT on 2/6/2009

1999 Suzuki Swift

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

Brad from Salem, UT on 1/26/2009

1994 Geo Prizm

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

Product Research

Features

Wiring Harness: This wiring harness prevents 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 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 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 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.

A
The Metra 70-1782 wire harness consists of a 13-pin plug with 7 pins along the bottom and 6 pins along the top half.
