Metra 70-1761 receiver wiring harness

This vehicle-specific wiring harness adapter makes connections between your new car stereo and your car's electrical system. It works with select 1987-up Toyota, Lexus, Scion, Subaru, and Geo vehicles.

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 it 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.

Product Research


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.

Metra 70-1761 Receiver Wiring Harness

Written By Josh, eureka,CA on Monday, March 02, 2015

Very simple to use

Pros: Every wire was labeled

Cons: Everything was good

Worked great for me

Written By Skittles, California on Tuesday, February 24, 2015

Crutchfield Customer Review (What's this?)

Easy set up once I figured out all the wires color co-originated. Seems to work fine for me. I also really like that it is plug and play with my car. Now if I ever want to put my stock radio back in I can super easy.

Pros: Does what it should.

Cons: No solder, crimps, or shrink tube included. I had my own so it was not an issue.

Crutchfield Customer Review (What's this?)

I was dreading having to cut the wires and solder them or do a half a$$ job by putting crimp connectors on and then wondering if I would have to put the old stereo back in if I wanted to sell my car and have to do it all over again! Then I thought, no way, I'm not doing it! I'm getting a wiring harness! Best decision I ever made! Plug it in and done! Thank you Crutchfield! No other company came to mind but yours!

Pros: Easy, quick, no mess, no cutting factory wires.

Cons: No cons.

More for Crutchfield's support!

Written By Karstyn, California on Sunday, January 04, 2015

Crutchfield Customer Review (What's this?)

I ordered this harness, but should have ordered a different one because my original car stereo had JBL, which requires a different harness, I called the Sup-port line and they sent out the correct one immediately, which worked perfectly. I have to presume this one would have worked correctly as well.

Crutchfield Customer Review (What's this?)

I think this took longer to do than putting in the radio. I didn't have any connectors for crimping the wires together, so I soldered them. It took a little while. But I know that they won't come apart.

Connect right up!

Written By Drvajeep, IL on Wednesday, December 24, 2014

Crutchfield Customer Review (What's this?)

Just connect the matching wires, and plug and play. Connectors are quality plastic and have a secure fit.

Pros: All the right matching wires.

Cons: None
