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.
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.

This harness was easy to setup. Since I already had everything else, all I had to do was strip the wires and connect them. Works for '90 amigo
Well made, easy to connect, couldn't ask for more!
The wiring harness that was provide for me by Crutchfield made the job a lot easier, and saved me a lot of time. I would recommend it to all my friends.
Pros: Easy to use
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
Everything was good technician had no problem installing
Pros: Everything worked great.
Cons: No complaints
Perfect for my car.
Pros: Easy installation

It's all good
Pros: It's good
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.
Cons: Doesn't fit 1999 Suzuki VitaraCrutchfield response on May 7, 2014 We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.
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.
Pros: Easy to understand
worked as advertised
Excellent product! Made wiring a snap.
Pros: Fits exactly as advertised. Plug and play with some wire connectors. Super easy and all wires color code correct.
Made for super easy install of new receiver...just match color coded wires then plug & play...
very familiar with these harnesses. Works great!!!
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.
This was the perfect fit for my daughters car
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.
This harness and directions were a huge help in preparing my receiver for installation. There was almost a one-to-one correspondence with the receiver's wires and once it was hooked up it snapped into my vehicle's plug. Thanks
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.
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!!
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.
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.
