This harness allows you to retain your Subaru's backup camera if you are installing a new car stereo with a rear-camera input. You'll also be able to use the handy auxiliary input in your Subaru (if equipped) if your new receiver has a rear RCA auxiliary input. The kit includes Axxess' AX-CAM6V converter that accommodates the Subaru backup camera's 6-volt power supply. The harness also provides the outputs you need if you're installing a NAV receiver. 

To use this harness, you'll need the Axxess ASWC-1 steering wheel control interface (sold separately) and a compatible aftermarket radio. You'll also need a vehicle-specific wiring harness to install your aftermarket stereo. We'll show you the correct harness when you enter your vehicle information into our online vehicle selector.

Does work w/OEM rear view camera and aftermarket head unit on 2018 WRX

Crutchfield customer from Columbus, OH on 7/21/2019

2018 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

This does in fact work for the 2018 WRX base model. After installing an aftermarket head unit, I got my rear view camera working with this item exclusively. Crutchfield service told me it doesn't work with 2018 WRX for OEM rear view camera. It DOES.

Pros: Works for OEM rear view camera with 2018 WRX and aftermarket head unit.

Cons:

Works with 2017 Subaru WRX

Crutchfield customer from Roanoke, VA on 1/25/2019

2017 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

Worked perfect in my case, 2017 Subaru WRX non navigation, non Harmon Kardon. For the camera I plugged in the power wire into the reverse signal from the 28 pin connector. If you plug into ign or battery hot you can turn on the camera any time those outputs get a signal. Can keep steering wheel controls for Sony XAV-AX100 with 3.5mm jack to blunt cut wires that splice into this harness.

Great product

Jared from Eagle River, AK on 10/22/2017

2016 Subaru Crosstrek

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed in my 2016 Crosstrek to a Alpine ilx-207. This harness had terrible reviews in the past about the pins bending and becoming mis aligned. This issue must have been fixed. I connected and disconnected this harness several times with absolutely zero problems. Back up camera works flawlessly with the voltage step down device which is included. Easy install.

Pros: Keep all factory features (with help from ASWC-1 for steering wheel controls)

Cons: None, really. Had to manually program the aswc-1 to get it to work with my radio. No biggie.

Brandon from Mount Perry, OH on 9/10/2017

2017 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

Just installed this with the Sony XAV-100AX head unit on my 2017 Subaru WRX and unlike the other reviewers, mine went right together. I looked and all of the pins were straight and I slowly but firmly inserted them together and they snapped right together. I even took it apart and put it back three times while I was test fitting and made sure everything stayed straight and good and it was fine. Maybe I got lucky or maybe they have fixed this issue that everyone else had. - If you are installing this on a 2017 WRX, do not buy the ASWC-1 module for your steering wheel controls even though this harness is prewired for it. I tried the module first which would only run 4 or five controls and kept erasing them randomly. All you need is a 3.5mm headphone jack cable. You can buy it online as a pigtail with the wires stripped back showing the red, white, and ground. Here is what you do: - Tape up the 10-pin black connector on this AX-SUB28SWC harness that is meant to plug into an ASWC-1 module since you won't use it. - 5-6 inches from the 28 pin connector, cut the three steering wheel control wires which are pins 21 (green/red wire), 22 (green/black wire), and 23 (black wire). - Strip the wires and connect them as follows: *Connect the green/red to the red wire on your 3.5mm plug *Connect the green/black to the white wire on the 3.5mm plug *Connect the black to your ground on your 3.5mm plug - Cut and tape off the 3.5mm plug tha

Pros: *Easier plug-and-play wiring *Includes a 12v to 6v converter for backup camera *Bad connector issue might be fixed because it went right together for me and had the updated and labeled red camera 6V power wire unlike the early versions that used a yellow wire.

Cons: *The prewired ASWC-1 wires are useless, use a custom 3.5mm plug as stated in my review and bypass the module. This unit can learn the buttons without the unreliable Axxess module. Just use the custom steering wheel controls menu when you wire it up like I did

Poor quality connector/pins

Samuel from Ann Arbor, MI on 7/6/2017

2017 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

The other reviews mentioning the connector problems are all accurate. I work in the automotive industry with these types of connectors frequently but I've never had to do this much babying and pin bending to get a connector to go in smoothly. DO NOT FORCE THIS CONNECTOR IN, since you're likely to damage the mating connector in the car, or one of the pins on this harness. After 5-10 mins of fiddling I managed to get it in, and it seems to be working well.

Pros: Works well once you manage to get it plugged in

Cons: Takes a lot of work and patience to plug the darn thing in! Main issue is misaligned pins with too much play so they can easily move out of position.

Great product in that it allowed me to use my factory back up camera. The 28 pin connector had issues keeping the pins aligned and therefore it was very difficult to use the plug. I also had to bypass said plug for the steering wheel control wires. 2016 Subaru Impreza

Pros: Retains factory backup camera

Cons: Faulty plug

Finally got it to work!

Crutchfield customer from Fernley, NV on 6/29/2017

2017 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

Got it to work! Destroyed first 28 pin connector pins trying to use force as advised by Crutchfield trying to get connector to mate. Received replacement harness and 28 pin connector again would not mate. Decided to try and put some dielectric grease on the male and female mating surfaces, and after about 10 minutes of messing with the alignment of the pins, I was able to "feel" and "walk" the mating surfaces together!

Pros: Once you get the 28 pin connector mated, everything works!

Cons: Trying to get the 28 pin connector mated

Nothing worked on it

Keith from Los Angeles, CA on 6/17/2017

2016 Subaru Crosstrek

Verified customer (What's this?)
Verified employee purchase (What's this?)

This thing is a piece of junk. The harness doesn't fit into the car harness. After over an hour of adjusting the pins, I finally got it to fit, but the ASWC-1 kept showing no connectiion on pin number 22, and therefore didn't work at all. I also tried to bypass the pin by hardwiring it into the car wiring, and after multiple ground locations, still nothing worked; Also, the backup camera didn't work, and the auxiliary input kept cutting in and out. I finally got frustrated and took out the Pioneer AVH-X491BHS stereo that I bought and installed and put the factory unit back in.

Pros: None

Cons: The backup camera, steering wheel controls, and the auxiliary inputs all didn't work.

Crutchfield response on 6/20/2017
Once we saw this review, our Tech Support team reached out to Keith to issue an apology and help him further. We'll either help him get the harness working the way it should, or help him return it for an exchange or refund.

All negative reviews below are true. Harness does not even come close to fitting. Axxess customer service could not provide one ounce of help to get me going. The whole install was flawless up until trying to get this thing installed. Crutchfield great as usual, but you have to talk to this vendor ASAP.

Crutchfield response on 6/19/2017
Thanks go out to Scott and other reviewers. We do apologize for any issues that you may have encountered. Our main man for vehicle integration, Darren, has reached out to Axxess, and they are investigating the plug fitment issue for us. We'll update our presentation once Darren hears the results from those tests.

28 Pin harness does not fit as advertised.

Len from Rochester, NY on 5/8/2017

2017 Subaru WRX

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was sent the older version of this product which contains a yellow 6 volt cable instead of the red one in the instructions. I can't speak for the more recent version of this product but the one I was given does not fit 2017 WRX 28 pin harness. The pins are too big and are fairly weak. This a little frustrating considering the purpose of this project is to ease installation, now I have to purchase additional components to complete the install.

This harness is garbage.. Pins are flimsy and do not fit well or at all. I bought a second one to see if I got a bad one but no. It's too bad. I love Crutchfield but they need to talk to Axxess and stop giving this to customers.. I spent an extra easy 4 hours fighting this harness and my local car stereo shop as well tried to help.. It turned a simple HU install into a major headache. I really hope they nix it.. I have a Toyota Tundra to do next....!!!

Pros: It showed up fast...

Cons: Really poor directions, Built cheep, Dose not fit well ( or at all )

The connector that plugs into the car is poorly made. Crutchfield had to send me a second one. The first one the pins bents and pulled out. The second one after many attempts of not being able to get it in. I had to send it to a shop. Once the install was done they stated the connector took the most time out of all the radio install. He said 30 mins to get the pins to line up. [ jason  Jul 21, 2017 ]
