Metra 70-1763 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 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.


Note: Your vehicle's wiring harness may not include a ground connection. If not, you'll need to make a ground connection between your new receiver and your car's metal chassis.

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 and sold separately.

Metro 70 -1763 Wiring Harness

Written By Eugen, Titusville, Fl on Sunday, November 09, 2014

Crutchfield Customer Review (What's this?)

1992 Nissan Hardbody PU Perfect fit with the the Nissan wiring connection. However, I ended up not using the harness due to the poor installation instructions which came with my new Clarion radio.

Metra 70-1763 for use in a 1991 Pathfinder SE with premium audio optio

Written By Johnny Haywire, Chicago on Monday, October 13, 2014

Crutchfield Customer Review (What's this?)

These adapters are generally great, but this one is only for the "standard" audio equipment on the 1991 Nissan Pathfinder SE. Mine had a premium audio option with a Sony single CD deck and rear-speaker-only amp. I couldn't use the rear speaker section of the adapter. However, the Crutchfield tech was really helpful and pulled up the diagram and talked me through my different option scenarios and gave me tips on where to splice in (for the rear speakers) and also specs on the OEM amp vs. my aftermarket stereo. All in all, a great experience with a knowledgeable tech and everything worked out well.

Pros: Easy to install, clear wiring diagram on back of package.

Cons: Only works with "standard" audio equipment. Rear harness needs to be bypassed and hard-wired for 1991 Nissan Pathfinder SE with "premium" Sony CD/rear speaker amp audio option. Not a big deal, but you could also use a diagram and skip the harness completely since you have to solder the rear speaker wires at the dash anyway. My only reason for using these adapters is to preserve the OEM wiring harnesses/connectors. If I have to solder have in-situ, I might as well solder the whole thing there.

It works great

Written By Maaakaaa, Colorado on Wednesday, June 18, 2014

Crutchfield Customer Review (What's this?)

It fit right for my 1994 Pathfinder. Everything works great.

Pros: Easy to install. Functions right.

Cons: None

Worked Perfectly the First Try

Written By apm300, Grove City, PA on Tuesday, June 17, 2014

Crutchfield Customer Review (What's this?)

Needed this to connect my new Kenwood Excelon KDC-X598 and new Polk Audio speakers in my '93 Nissan 300ZX. Instructions were clear and the process was easy (and fun). I liked how the wires were already prepared for me to connect - needed only to pull off a half inch of covering on the ends.

Pros: Perfect for my needs; ready to connect

Cons: None

Sony DAX-S210X

Written By Dan, Va. Beach, VA on Wednesday, June 19, 2013

Crutchfield Customer Review (What's this?)

I was only looking for a basic in dash replacement for my 240sx. The sale price caught my eye, and not to mention it's a Sony product. My music library thru an ipod nano pretty much stays put inside most of the time. I also listen to Pandora quite a bit and being able to access it through the head unit is something now that I can't live without. This unit, coupled with my powered subwoofer, makes my 2 hour daily work commute much more liveable. And more importantly, CRUTCHFIELD SERVICE ROCKS!!!

Pros: Full of high end features for the price, excellent sound quality once dialed in

Cons: Takes some time and patience to navigate through the menus. If you're the type of person that prefers designated knobs for basic functions, i. e. bass, treble, fader, etc. , then this is not for you

Crutchfield Customer Review (What's this?)

I just connected the wires by twisting the copper/aluminum wires together and taping with electrical tape. In normal use this will do fine.
