Metra 70-1739 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
  • dimmer
  • 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. You can also call an Advisor for more information.

Almost perfect

Written By SAABDriver, Washington on Tuesday, January 20, 2015

Crutchfield Customer Review (What's this?)

This harness is almost perfect. Brittle plastic is the only shortcoming.

Pros: -Proper fit. -Wires are labeled on the insulation; you don't even need to look back and forth to the legend on the packaging. -Insulation is "clipped" at a good length from the end of the wire which speeds up installation.

Cons: -Plastic too brittle. Like another reviewer, when I connected one of the new connectors to the existing one in the car, both of the holding clips broke off. I was able to wrap a zip tie around to hold it together but would have preferred not to have to.

radio wiring adapter for Saab

Crutchfield Customer Review (What's this?)

Very easy to do--snapped right in, and even was color-coded to match after-market unit wiring. A snap to do.

Pros: easy to use, snapped right in, piece of cake

Cons: none

Great connector, but brittle plastic

Written By MichaelB, MN on Monday, January 27, 2014

Crutchfield Customer Review (What's this?)

The wiring diagrams made this very easy to wire up, and install. The only problem was that the plastic was rather brittle, so when installing it the retaining clips snapped off of one of the connectors. Not really a big deal, just used some tape to keep them together, but a little disappointing.

Pros: Easy installation

Cons: Retaining clips broke off

Written By Colin S, Albany ,NY on Sunday, November 03, 2013

Crutchfield Customer Review (What's this?)

I was nervous regarding this install due to the quirkiness of saab wiring. This harness worked so well that I plan to upgrade from the older Sony head unit I just installed to a new touchscreen unit.

Pros: Cost and ease of application

Excellant

Products are very good. Greta customer service

Brilliant.

Written By Paul, Phoenix, AZ on Thursday, June 07, 2012

Crutchfield Customer Review (What's this?)

Piece-of-cake installation. This harness, coupled with Crutchfield's master sheet, made the install go very smoothly. Wired up the harness in the comfort of the air-conditioned house, and then just had to snap it in place in the hot and sweltering garage.

Pros: Fit perfect for the 1990

Cons: None.

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.
