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.

Harness Location: The factory plug that mates with the Power Harness is located in the factory radio cavity of the vehicle. The factory plug that mates with the Speaker Harness (used to bypass factory amp) is located at the external factory amp location (in rear of vehicle). The 17' Speaker Harness will need to be plugged into the external factory amp and then run up to your in-dash aftermarket head unit for speaker wire connection.

Note: An additional aftermarket amplifier is recommended if your vehicle is equipped with Front Tweeters, Front Speakers, Rear Speakers, & Factory Subwoofer.

A pointless piece of the puzzle

Written By John doe, Wyoming on Thursday, December 13, 2012
Crutchfield Customer Review (What's this?)
 
I rated this a 4 because for the quality it's great, now if only I truly needed it..... I made my own essentially. So this is a waste of money for me. However now I've got labeled factory wires to wire anything else I may want to.

Works well in 2007 Honda Civic Si

Written By Mr. Mike, Adamsville GA on Saturday, September 01, 2012
Crutchfield Customer Review (What's this?)
 
There were no problems with the functionality of the harness. You will get wires that are about 14 to 16 feet long, so you will have to cut them as there will be no room behind your dash to stuff all that wire. This is no problem at all because I would much rather have too much wire than not enough. You will lose the use of your subwoofer and steering wheel controls, so an aftermarket amplifier and steering wheel control adapter will need to be purchased.
Pros:
Works well
Cons:
None

Not for 2008 CRV EX-L

Written By Matt, Chantilly, VA on Monday, August 13, 2012
Crutchfield Customer Review (What's this?)
 
This harness is not needed on a 2008 Honda CRV EX-L with factory subwoofer; there is no amp to plug it in. Crutchfield techs were great though and sent me out the correct one, which installed easily.
Pros:
NA
Cons:
NA

WRONG PART!!

Written By Lyadonna22, Fayetteville, AR on Tuesday, May 08, 2012
 
I'm sure this is a fine product for the right car, but Crutchfield sent this to me for use with my Honda CR-V and I had to go out and pick up the correct part. The wires are CRAZY long on this unit, too... Not sure why you would need that much, but I guess it's always nice to have options?

Ok for basic radio

Written By car audio, woodbridge VA on Saturday, February 14, 2009
Crutchfield Customer Review (What's this?)
 
This harness is ok only for basic aftermarket install as it will still require you to splice/tap into VSS/VSP wire even though it is present in the OEM connector. The 09 Si civic has two illumination wires and most radios only have one (this connector only has one) so it doesn't help. It is also important to note that you WILL lose your sub woofer with this harness if you do not get an amplifier as all aftermarket radios only have 4 channels. The Civic Si needs at least five (you can run the front mid's and tweeters in parallel off the same line (thanks Crutchfield for that advice, works great)). This will work great as I will soon buy an amp to get back my subwoofer. I think this harness should have had the VSP wire (that is common in GPS aftermarket units) as it IS in the OEM harness. As it is for the honda civic they should know and tell you that there is an issue with the illumination as well. You get tons of wire so there many options to run the harness. Center console to under the seat only takes about a third of what they give you. Good quality wire too! Hope this helps everyone looking at this.
