Item # 12071034L | MFR # 71-034LC
These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings. Warranty: 60 days.
Note: Some aftermarket speakers have terminals that are wider than this harness's slide-on connectors. You may need to widen the harness's female slide-on connectors, or use the slide terminals that may be included with the speakers. If you need to connect your new speaker's connectors to the Crutchfield harness, soldering is best, and crimping is also very popular — see "Accessories."
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.
Average Customer Review(s):
Works great - good quality, solid connector.
These are a no-brainer. Beats stripping wire and soldering an day of the week.
Pros: Easy to install
Replaced my wife's Corolla 2010 speakers. True enough, no splicing. Installed new speakers without hassle.
Perfect Match for my upgrade!
The harness fit the rear deck speakers of a 2004 Toyota Echo, however, there is a side 'bar' that does not fit into the female harness that has to be manually trimmed away using a box cutter.
Pros: Fits with slight modification.
Cons: Needs slight modification.
If they didn't add them for free I would have to buy them. It just makes it way easier and one less thing to think about for the installation.
Pros: Much easier and quicker than cutting and stripping wires.
Helped to make a quick install.
Crutchfield provides detailed, easy to follow installation instructions. These things fit perfectly in to the stock connector. Unfortunately the negative connection to the speaker was a pretty tight fit on all for speakers. Still functional, and the important thing is the connector fit well to the stock connector.
Pros: Fit well to stock connector. Detailed instructions.
Cons: Negative terminal on all four speakers was a little tight.
This did not fit in the rear of my 2003 Toyota Camry.
Cons:Crutchfield response on 12/20/2016 Once we saw this review, our Tech Support team reached out to Jacob to issue an apology and help him further. We'll either help him get the harness correctly correctly, or help him return it for an exchange or refund.
Item was not a direct fit. There was a rigid plastic alignment tab running the length of the plug that I had to trim off. It was not a big deal. Used a boxcutter. Once trimmed, it fit fine.
The Toyota connectors fit correctly, as did the connectors to my replacement speakers. The wire length was the same as the factory wires. This is a great product to make the job easier.
Perfect fit, plenty of wire for the application. Easy installation.
Pros: long wires, great fit
Cons: Connections to speakers were tight and difficult to secure completely without damaging speaker inputs.
Wiring harness is the way to go for hooking up after market installation. Takes a few seconds rather than old way of splicing and soldering.
Made hooking up speakers very easy
Pros: Easy install
Cons: None really
Generally the Crutchfield harnesses are great which makes speaker installs so much easier, especially in tight working areas. This time, however, after some difficulty inserting the male side harness to the female clips mounted on the rear deck of my 2003 Toyota Camry LE, I noticed that the little "rail" along the male harness box was situated on the wrong side of the plastic harness housing, and did not match the female side inside groove. ie. matching up the male and female sides, if the rail is on the left (or right side), the groove was on the bottom. Impossible to attach as is. My solution: with a sharp razor cutter, carefully cut/shave off the rail completely until its flat with the box. It was quick and easy; careful not to cut anything else. Perfect insertion and fit as a result, click-locked in place without issues. . . . did I void my warranty?. . . If not for this design flaw, I would have given 5 stars.
Pros: Harnesses makes for easier install, and this harness was free with my purchase of 6x9 3 way JBL speakers.
Cons: Needed to "McGyver" the harness box by cutting the guide rail off with a razor cutter on the male side for it to fit. Overall it required a bit more time to figure out the issue, think of a fix (including weighing the option to send it back to Crutchfield at the cost of valuable time), deciding, and then expedite my "McGyver" plan. Other than this design flaw, additional time required, I am happy with having it. The downside is NOT having it.
It couldn't get any simpler than this, it's connect and go, no splicing or color matching. They fit my 2005 Toyota Corolla perfect and openedd up the doors to amazing sound.
Pros: Easy, quick, free DIY install
This really makes the install easy and smooth, no splicing required!!
Simple plug and play
Pros: No wires to cut or splice
Made connecting the speakers so much easier
Pros: fit great both sides
These wiring harnesses were definitely the easiest part of the speaker install. The harness has a speaker connection on one end and the Toyota factory connector on the other - eliminating the need to splice any wires.
Pros: Custom fit
these were necessary for the installation of my new speakers
Pros: ease of use
The harness connected easily and was the right one for the vehicle.
These are the adapter cables for the rear-deck speakers in a 2005 Toyota Corolla. They fit and work out of the box.
Pros: Snug fit.
ayudo en la instalacion de las bocinas. It helped with my speaker installation.
Cons:Crutchfield response on 5/19/2015 Translation provided by Crutchfield's International Sales & Support team.
Made self installation easy
Pros: worked as intended
Cons: worked as intended
This is exactly what I needed and it worked out awesome. It's a perfect fit on my alpine type r 6x9's. they are a perfect length, not too long and not too short
Pros: Perfect length
Makes installation much easier.
Pros: Eliminates wire splicing
Can't beat "included free". Saves time soldering or figuring out other connections. Works great.
These fit perfectly and were a snap to use on my 2004 Camry.
Pros: Works perfectly!
Perfect factory fit for rear 2011 camry.
Pros: Crutchfield never stears you wrong.
plug and play
These connectors frustrated the heck out of me until I discovered that they will not fit the OEM rear deck harness connectors. Fortunately, the drivers I was replacing provided the connectors that I required. I simply butt spliced the original connectors onto these and I was able to complete the installation despite Crutchfield's recommendation that these would indeed fit.
Pros: These connectors do fit a 2002 Camry's front door speakers.
Cons: Do not fit 2001-2006 Generation 5 (XV30) Toyota Camry OEM rear deck speaker connectors.Crutchfield response on 11/18/2014 The front doors and rear deck do indeed require different speaker connectors, so it sounds like you might've been sent the wrong ones. We're double-checking our warehouse inventory to make sure this doesn't happen again. Thanks for letting us know.
Crutchfield makes it so easy with these direct fit wiring harnesses. Best part is they are free.
Pros: Awesome. Something so simple but makes things do much easier.
This will make your install much easier and it'll save you the time of soldering wires together.
It was nice to not have to splice the wires. Crutchfield really made the speaker upgrade easy with knowing the vehicle and what adapters were needed for a perfect and easy installation.
Pros: Fast and easy installation
Easy plug and play action. Little tougher than front doors. Had to wiggle and push a little harder but still good product.
Pros: No cutting
Cons: Tigger fit than front
Easy to use.
Pros: Front harnesses plugged right in
Cons: Back harnesses had to be modified for my car
These harnesses made the connection to the new rear speakers I installed so easy.
Pros: Easy installation of rear speakers
If all you are doing is replacing factory speakers then these will be needed.I use an amp so these were unneeded
Pros: Quality is good
Cons: Useless if you are running an amp
I love using these adaptors. As a professional mechanic I never want to damage the factory wiring if possible and these make that and speaker installation fast and easy.
Pros: Easy to use, fast installation
Would give a 5 star rating based on the front ones. They fit perfectly. They mounted to the stock mounting points and were the exact right length to avoid interference with the windows. Unfortunately, the rears had incorect connector. The wires were the correct length and the pins were correct, but they would not fit the stock conectors. I spent 20 minutes with a pick pulling the pins from all the connectors and connecting them bare and wrapping them with tape. Still better than not having them, IMO, since I didn't have to cut any wires. But was frustrating when I got the speakers installed and couldn't plug them in.
Pros: One of them was exact perfect fit.
Cons: One of them had wrong connectors.
This product is a no brainer, ease of use is just great, can't see using anything else if this is available for the application. Should be a standard with every install kit purchased.
Pros: Easy to use
Woah, let me tell you. This wiring adapter, boy, does it adapt wires. I mean, what else can you say about a wiring adapter? It even gave my wife a foot rub! Once, I bought a wiring adapter that called me a jerk and refused to adapt my wires! Turns out it was for a different car manufacturer, so it kind makes sense. But this guy, woweey! Consider my adapted!
Pros: It fit my car. It functions for its intended purpose.
Don't get no easier, just plug and play
Good quality, fits great!
Pros: Works great! Quality, fit
Using this harness made speaker installation a snap!
Pros: Easy install
Hooked up to 94 Camry really easy. Thank you!
Couldn't be easier
Pros: No citing or crimping required
Perfect fit, not much more to say!!
Pros: Perfect fit, made my install even easier and was free Thank you crutchfield!!!
Did not fit factory harness, couldn't use them.
The wiring harness worked as expected but the speaker bracket didn't match and didn't come with instructions.
Speaker Harness: These speaker harnesses prevent you from having to cut your vehicle's factory speaker plugs when replacing your factory speakers with aftermarket car speakers. The speaker harness features two female quick-slide connectors on one end to attach directly to your new aftermarket car speakers & a proprietary Molex connector on the other end that connects to your vehicle's factory speaker plug.
Quick-Slide Connectors: The speaker harness is equipped with a large (positive) & small (negative) female quick-slide terminal. These quick-slide terminals fit directly onto most aftermarket car stereo speaker terminals (slight crimping may be required). In rare cases that the quick-slide terminals do not fit your car speaker terminals, you will need to solder the speaker harness to your aftermarket speaker's terminals or replace the quick-slide connectors on the speaker harness with the correct size terminal.
Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.
Quick-Slide Terminal Measurements: The positive female quick-slide terminal measures 0.205" (inner width), while the negative female quick-slide terminal measures 0.115" (inner width).
Wire Code Chart: Two identical speaker harnesses are included.

The best compromise between price and quality that is confirmed by previous order of speakers for a Kia Optima. If it worked previously, why experiment? This is the same reason why I have been purchasing from Crutchfield catalogs since the early '80s.In the particular case of speaker wiring harnesses, why splice when everything can be plugged together?
