Metra 70-2103 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.
What's in the box:
- Receiver wiring harness
- 42" Red wire (with female quick slide on one end)
- Fuse tap (with male quick slide)

A little tricky to install in our 2006 Pontiac G6. (But we are completely newbies). Looks awesome, works awesome ! Thanks Crutchfield!

This product works flawlessly with my Chevy Cobalt. Everyone told me that this was the adapter i needed. I am quite happy with how easy it was to connect everything and the harness works like a charm. I would like to see it get added to the list for Chevy Cobalts, because it is a proven adapter that works, I can not say for the newer models, but my 2006 works great with it.

I have looked ALL over for this harness. I am actually in installer in Rochester, NY and I have called all of my distributors for this harness. Nobody has it. Crutchfield does (of course)!! The only problem is that I have heard that if you need work done on your vehicle, you have to put the factory radio back in (it is a version of the GM Databus system call LAN). I left the factory part of the harness hanging down where I could get to it without removing the whole radio trim again. Thanks for the great product Crutchfield!!! Justin

More details on the Metra 70-2103 Receiver Wiring Harness
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.
