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.

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, 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 & sold separately.

Written By Ktran, San Jose, Ca on Tuesday, April 14, 2015

Crutchfield Customer Review (What's this?)

Great product. It fitted well with Pioneer DEH-X6700BT receiver for the Toyota LE 2002. I am a very happy customer!

Pros: Fit like a pair of gloves. Every cable on the hardness was matching perfectly to each cable that came out of the Pioneer DEH-X6700BT, car receiver. I just needed to pair the color code and crimped them together.

Cons: none

easy peasy

Written By Gary F., Oregon on Thursday, April 09, 2015

Crutchfield Customer Review (What's this?)

I liked getting this wiring adapter, I didn't realize that you had to connect the wires, and I didn't have any crimp connector, I used heat shrink tubing and soldered the connections, so if you are doing this job with this kit, you will need come splice caps and a crimper to finish the job but this kit made the connection very easy.

Pros: having the correct connectors is so terrific

Cons: the wires are not connected and you might not have the tools to do it but when you figure out what you need this kit will make the connections fool proof and solid

Worth every penny

I have used these before and they are great. First time wiring a Lexus and it was really a different adventure to have to wire around the factory amp. These connectors made the job easier.

Pros: perfect fit

Invaluable

Written By Alberto G., San Antonio, TX on Tuesday, March 31, 2015

Crutchfield Customer Review (What's this?)

Saves time and heart ache. The fact that it comes free from Cructchfiled is a big bonus for me. The wiring color codes matched up perfectly with the new stereo color codes. I do not recommend any new install with out using this product.

Pros: Easy to install. Color coding on package.

Cons: None

Easy to use, perfect match for a simple Sony car stereo. Made the installation easy.

Pros: Easy to match the wiring to the car stereo Made the installation of the stereo easy

Cons: Wires could be a higher grade, it seemed more difficult to connect to the wires on the car stereo harness than it should have been.

What can I say? It was a good wiring harness. Everything matched perfectly and it seemed to be well constructed.

Attach the Blue Wire!

Written By DaveZ, New York on Friday, March 20, 2015

Crutchfield Customer Review (What's this?)

Perfect, and a bargain when it's free with your stereo! Only thing is: DO connect the blue wire to the blue & black "remote" wire on your stereo, even though that remote wire is taped of. The instructions don't specify that, especially if the cable colors don't sync up perfectly.

Pros: Free with stereos that require it.

Cons: Downloadable instructions not 100% idiot proof

Flawless Install

Written By WOW!, Ohio on Tuesday, March 10, 2015

Crutchfield Customer Review (What's this?)

Without this wiring harness, I wouldn't have attempted the install. Super simple transition from OEM to the Kenwood. I soldered the connections and used shrink tubing rather than use butt connectors so it took me about 15 minutes longer to install - time well spent. With a good harness, there should be no reason for paying for installation, EVER!

Pros: Worked flawlessly!

Cons: None
