Works perfectly

Harness worked perfectly as intended, I was able to retain my backup camera and along with maestro module I retained all my steering wheel controls. My car was a Subaru WRX 2016 without the Harmon kardon

Great harness for Subarus

Great Harness for installing my aftermarket head unit into my STI. Came with everything needed and splicing the wiring was pretty easy to do.

Paired up perfectly with my car's oem harness. Took me about 20 min to connect all the wires to the radio.

Works as expected. Easy plug and play with detailed, colored wire diagram. I was able to keep all factory steering wheel controls for my '17 wrx with an aftermarket pioneer 2660 Nex.

Pay extra for the harness build!! This was no easy "Plug and Play"

I am so glad that I paid for the harness build from Crutchfield, because even then this thing was impossible to figure out. The installation instructions from Crutchfield were so minimal that unless you're doing this stuff day-in-day-out, it would take a very long time to both figure it out and then to do the actual build. I am so grateful that they had patient people on the other side to help me walk through it. The diagram that comes with the harness was so confusing and inadequate. Additionally, because I paid extra for the build, all the extra wires in this item just served to confuse even more.

Everything you need

This is the wiring harness you need to connect your aftermarket head unit (assuming you get the Maestro RR module as well) to the factory vehicle harnesses in the dash. The harness is basically plug and play; you only have to crimp or solder the like-colored connections from this harness to your aftermarket head unit harness (which is laid out in the PDF instructions on the Maestro website) and plug into the vehicle-side harness. On my 2017 Subaru WRX, this harness allowed me to retain my steering wheel controls and OEM backup camera (this harness takes care of the 12V to 6V step-down needed in several Subarus to retain usability of the OEM camera). Install was confusing at times, since there were several bundles of wires that came with the harness that I didn't need, but this is probably to accommodate several car models. Overall, everything works as it should.

Overall the harness is a good deal. It makes the installation a lot easier than having to figure out which wire on the car goes to which wire on the radio harness. The only reason I give this 4 stars is that the wiring harness can be a little confusing. The harness apparently is used for many different versions of Subaru Outbacks, and maybe other Subaru models in general; I'm not sure. As a result, there are a lot of connections which are unneeded for the stereo set-up in our car. The directions are not completely clear about that, so I was a bit overwhelmed when I plugged in the wires I needed, and had a bunch of stuff left over. Thankfully a call to the Crutchfield help line cleared that up quickly. The wiring harness appears to be of high quality, and I really liked that the plug colors match those on the car. That color coding made it a lot easier to figure out "what goes where."

Worked as intended. Depending on your Subaru model and options you will end up with extra cables since it is designed as a universal kit for multiple models.

Good product but check your RR module first.

Good product, except that I had a 256 RR module instead of a 512 module. This harness CANNOT work with a 256. So, check the back of the module before buying this and see if there is a (256) or (512). Otherwise, good quality and simple installation.

I feel weird reviewing a bunmch of wires. I needed them to make my stereo work. Crutchfield attached what was necessary to their harness. It was all worth while, and seems like good quality. I would buy it again if Crutfield said I needed it for another installation.

Harness seemed pretty hard to wire up properly so I paid the additional money for Crutchfield to wire it for me.. beat decision I've ever made.. came professionally wired up and it was a plug and play type of situation after I got all my products..

awesome harness, worked like a champ!

This harness worked like a champ! I was able to install in a day, and although there was one part I was unsure of, the idatalink support staff answered my question immediately. Would definitely use this again on my next install

It's a harness

had to modify the harness to work with manual cars in order to get into setup of an alpine ilx-f309. Also, had to use the OBD2 port to keep the rear-view camera functionality.

Worked perfectly for my 2015 Forester. It took a little time to sort out which cable went where, which ones weren't going to be used, etc. So glad I paid extra to have Crutchfield do the wiring for me (ReadyHarness service).

pre connecorized harness

This review is for the assembly harness that Crutchfield made all the connections for me so that it was literally a plug and play install. Having done multiple stereo installs through the years I will simply say this is a game changer. I will never do another install without this option. Having Crutchfield solder the connections in a bench environment with heat shrink tubing is a far superior solution than wire nuts and electrical tape at my kitchen table. Such a bargain and time saver, highly recommend!

Poor quality, returned

It's a simple harness but nonetheless, this was so poorly made that it was shifting and needed to be returned/ replaced. Second one also returned. Had to return the radio too as this seems to be the only game in town for interface modules.

Makes wiring easier. Necessary.

This is the magic that lets you wire your radio to your car from the comfort of your kitchen table. Another necessary device but it works well. The instructions are not in the box, you have to go to the iDatalink website to get specific wiring instructions for your car. It looks like you are building a spaceship, but the PDF instructions are well laid out. I printed it in color to help with the wiring. I used shrink-wrap over the connections to make it look professional. Electrical tape is not preferred because it gets so hot behind the radio that electrical tape will be a mess and possibly come undone. Use shrink wrap. You can also get a BIG shrink wrap to cover the entire bundle after shrink-wrapping each individual wire. That will REALLY look professional and be easier to manage. For my Subaru I had 19 wires to connect and heat-shrink. This also has an ODBII cable to connect to compatible headunits. Pretty cool. On the Kenwood, you can display analog gauges for temperature, pressure, RPM, speed, some other stuff. I thought I read somewhere that you can download additional gauges for the Kenwood including a "track-day" package. Between this wiring harness and the Maestro interface module box (also required), it's a miracle all that stuff fit behind the radio. It is SO jammed back there, there is no more room for even a single wire. That's why shrink-wrap is the way to go, to make sure your wiring connections don't come undone when you stuff ever
