All you need to connect ads-mrr and head unit to your Toyota.

Pros: Clear instructions, good fit, covers all the ways a Toyota needs to connect.

Cons: The parking/e-brake sensing connection of this harness kit may not be supported by the vehicle, may need to have that wire connected from the head unit directly to the parking/e-brake switch.

This is tricky, the kit requires you to splice into your vehicles back up camera, mine still doesn't work and there are no step by step instructions or images that are clear to follow. I am disappointed in this kit to say the least.

Pros: None that I can say

Cons: If you don't know what you are for sure doing, get a professional to do it for you.

Instructions Suck!

Matthew from Valley Center, CA on 4/6/2019

2011 Toyota Tundra

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

The only reason I gave this thing 2 starts was because it actually worked and is pretty much required. The Installation instructions are ridiculous. You can get more meaningful information off of a kids restaurant table mat! While I understand there are many configurations, there should be a web page with more detailed information. 2 connectors shown on the wiring diagram for a Tundra were not even valid in my configuration. This turned what could have been a two hour install into overnight as I had to get clarification of the connections.

Pros: It actually works once you get the needed information.

Cons: Installation instructions are vague that they are pretty much worthless.

Purchased this after receiving an aftermarket head unit from Ebay (that did not have the correct cables). The customer service was better than I could have expected, the agent went through everything with me and gave me every option so I could decide which price point I wanted to go with. The actual cables are perfect and install guide was easy to understand, absolutely amazing product, you can't go wrong with this, and it is worth every penny. Don't skimp on the cheaper cables, you will be able to tell the difference in sound

Crutchfield customer from Georgia on 3/12/2019

2011 Toyota Prius

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

Installed this in conjunction with the iDatalink Maestro ADS-MRR Interface Module. The installation was a FREAKING NIGHTMARE. My husband is an electrical engineer and this wasn't his first install rodeo. The module had to be re-flashed multiple times to get it to work properly. The connector that Maestro said should have the reverse camera (per their instructions) did not exist in our vehicle. Crutchfield confirmed this with their own diagrams of the car. Crutchfield helped him find the correct connectors and signals that then had to be tapped into, but the wires were pretty hard to reach and there wasn't much length to work with. The e-brake signal was not recognized by the DVD player, because the signal was not present where Maestro was looking for it, and so he had to find ANOTHER connector to tap into in order to bypass the Maestro and feed the signal to the receiver. Then he had to do another bypass because the reverse signalling to trigger the backup camera was also not recognized by Maestro. In total, he had to splice into six different signals to get the Maestro working. It is a design issue, not that they put the wrong harness in the right box. This could have all gone smoothly if Maestro had used the right wires and connectors! In all, he spent 15+ hours across 5 days and 5 hour+ phone calls with different Crutchfield techs. Kudos to Crutchfield for the assist, but stay away from this setup if you value your sanity.

Good harness (if overly long and bulky) that connects everything that needs connecting ... once you figure it out. The instructions could use some additional detail. As it is, it took some deductive work and eventually a call to Crutchfield service to get all the connections right.

Worked, But Not Without Difficulty

Brandon from Missouri City, TX on 12/6/2018

2015 Toyota Tacoma

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

This is a solid harness, and it did exactly what it was supposed to. I struggled with the instructions (which take the form of a fairly brief per-vehicle portion of a very large PDF available on their website) for my vehicle. Just simple labeling of the various extenders and sub-harnesses would have gone a long way - some could have been immediately put aside if I had understood what they were right away. My install also didn't perfectly match their picture (I think they tried to fit too many variants into the same vehicle instructions).

Pros: Only have to go through the pain of install once - then you enjoy it forever

Cons: Takes time to understand and rig up, may have to blaze your own trail if the instructions don't match up perfectly

Connects to factory harness for a clean installation

Jerry from Los Banos, CA on 12/4/2018

2010 Toyota Prius

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

I had a problem with the radio not turning off when the car was shut off. I called tech support several times to resolve this. They were very patient and knowledgeable but, didn't quite know what the fix was. They sent me a replacement interface module, but the problem remained. Not quite sure if there is an incorrectly wired wire harness or if there is a software bug in the module. I spent some time going over the wiring harness and came up with a solution that works.

Pros: Allows neat installation to factory connectors

Cons: Diagrams are OK but, wish there was a pin-out diagram of the Maestro module.

Easy to use, but quality problems

Jeffrey from Austin, TX on 10/3/2018

2011 Toyota Sequoia

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

It seems my experience is unique, but I had all sorts of problems with my install: intermittently dropped audio completely, intermittent dropped left-side audio, intermittently missing factory satellite radio, and intermittent fader/balance controls not responding. I think my problems are finally debugged to a bad connector in the harness. With everything powered up and audio playing (but sitting just outside the dash), I wiggled each connector to see if I could duplicate my problems. I was able to duplicate the audio dropping both complete and left-side by wiggling the translucent adapter that is part of "step 3" near the "connect amp. adapter" words in the instructions. I hope the replacement that Crutchfield is shipping to me will fix the problems once and for all.

Pros: Easy to match up connectors

Cons: Difficult to troubleshoot, no diagnostics from Maestro unit

Mark from Gardena, CA on 9/16/2018

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

Made installing a head unit in my Toyota FJ so easy. Basically this harness is the one that connects to the factory harness, there is one plug on the harness that is not used, and another one that is provided is the one you will need to plug into the main harness. Other then that there was an obd2 connector that goes on the harness as well, the harness then plugs into the maestro unit and there is a wire that is color coded almost exactly as the head units colors so connecting them was fast and easy. If you have a toyota, this and the maestro make it much faster then cutting and hopefully matching up the correct wlres.

Pros: harness plugs directly into factory harness. was easy to figure out even though documentation was sparse worked right off the bat, even though i wasn't quite sure i wired everything on the harness correctly with the maestro unit.

Cons: nowhere does it tell you to use a provided separate harness for the 3rd connector that connects to the factory harness. The kit provides like 3-4 extra connectors for different cars i'm supposing. But overall, that was my stumbling block for about 5 minutes till i connected the sub harness.

Straight forward setup, can be confusing to connect.

Dallace from West Harrison, IN on 4/13/2018

2008 Toyota Tundra

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

Lot of wires/connectors, but they only fit in one place so its just a matter of connecting everything that has a mate. In my installation there were a couple left over which does make it a little confusing, but I got everything hooked up. One thing I was surprised about is that I had to still splice into the factory wiring. There is a 24 pin connector that has a 4 pins you need to wire up for the factory rear camera. I really believe this should come with the kit. Sure it would be a little more work for them to either send a couple different dongles, or maybe send you just the connector with pins not inserted if they are different for different Toyota's. I ended up calling Crutchfield because I wasn't sure I needed to actually cut/splice into mine since all the other connectors were supplied. They were super helpful and I was able to finish the install. But other than that, the install was smooth, and I finished the entire install in a couple hours.

Pros: Lots of integration Easy to program

Cons: Quite a few connectors Some cutting/splicing still required on factory harness

Jonathan from Columbia, SC on 3/2/2018

Verified employee purchase (What's this?)

I would give 0 stars if possible. This thing is a piece of junk. I'm a Commercial A/V Design Engineer and I deal with microprocessors everyday. First off only being compatible with Windows and only with Internet Explorer is trash... Let's pick the worst browser on the planet to use... Sure, why not... Next, even after installing the plugin I end up switching USB ports on my laptop like 4 or 5 times just to get the computer to recognize the brain. Once I finally get the stupid thing to show up it goes through the process just fine and says that it flashes successfully... NOT!!! So, after flashing, hooking the thing up, unhooking, re-flashing... 4 or 5 times I finally get the thing to work... So, I get my dash all put together and I'm working in the dark by this point... As I'm cleaning up I'm listening to music and forget that I haven't tightened the ground on my battery all the way back... Then I reach down and turn the key... Yup, it flashes a couple times and I jump out and tighten the cable only to find that the head unit won't come on again... I guess this blasted piece of junk get's erased every time you have some little power glitch... What a pile... I'll update this review after I disassemble my dash for the 3rd time and re-flash this thing again (probably 6 or 7 more times to get it to work)... At least for the 10 or 15 minutes it was working it actually allowed me to power the head unit on... This thing has wasted 4 or 5 hours of my day!!!!

It worked great. I took my time putting it together. I went to iDatalink, reviewed the wiring schematics. Flashing the black box module via Weblink was no issue. My assembly included Kenwood DVD receiver, Sirius satellite radio and the iDatalink module. There is a lot of wires which maybe intimidating but wiring is straight forward. My steering wheel control worked. My gauges are functional on my Kenwood DVD receiver. My TPMS display is not showing but it maybe due to my 4Runner edition. I am enjoying it and I would recommend it and buy it again if I have the opportunity.

Doesn

Verified employee purchase (What's this?)

Not impressed. Doesn't work as promised. It was sold by Crutchfield who's support team just reads out of a manual when you ask for help. The iDatalink people were more informed about it and helpful, but the sale I got and how this would work were not in line with each other. It doesn't give full functionality to the steering wheel controls as they were. It makes the Steering Wheel controls triggers for various settings included whiting the idatalink once its formatted to your vehicle. I think thats ok, but the salespeople should be aware of its actual capabilities and be able to manage customers expectations.

Tom from Mount Pleasant, SC on 8/8/2017

2009 Toyota Camry

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

This harness worked perfectly with my Camry's wiring, so I could connect all the features of my new stereo to the existing switches and sensors of my car. I didn't have to splice any wires, just connected the harness per the instructions. One thing to note, it does not connect the car's built in bluetooth microphone. Apparently the built in microphone is amplified, which is not compatible with after market stereos. Fortunately, most/all new stereos come with their own mic.

Pros: Complete wiring harness

Cons: Directions could have explained the lack of microphone better

Did what it was supposed to

Scott from Meridian, ID on 7/31/2017

2010 Toyota Tacoma

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

It helped make my install much easier. My 2010 Tacoma had some steering wheel controls that I wanted to keep and even allowed me to modify the uses. I have a backup camera in my rear view mirror and I finally said the heck with it trying to integrate the camera into my pioneer avh2330nex head unit....maybe I'll try to figure it out down the road( pun intended). A must if you are using a maestro idatalink but the wiring diagram is terrible. The harnesses clear up wire color issues but you will end up with a ton of extra parts, better than the alternative but a product list would be VERY helpful.

Pros: Everything you need to wire your head unit

Cons: Wiring diagram LOTS of extra harnesses

The wiring harness did exactly what was needed. The reason for the 3 star is the mediocre instructions.

Without them I would be wondering if I made all the correct connections.

2006 Tacoma with JBL audio, straight forward plug-in play harness

Brian from Oxnard, CA on 6/4/2017

2006 Toyota Tacoma

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

2006 Toyota Tacoma Double Cab with JBL audio. Installed Kenwood DDX6903S head unit with the IDatalink Maestro ADS-MRR. The harness works great, plug-in play, I only had to solder a few wire from the HRN-RR_TO1 harness to the Kenwood head unit harness. I had to call Crutchfield and Maestro tech support, both were very friendly and helpful. I had an issue at first with the Maestro box, called Maestro, they said I need to re-flash the unit. Follow each step on the installation diagram in order. The steering wheel control was only partially working, called Maestro, I found the adapter from the factory harness (steering wheel control) that plugs into the HRN-RR-TO1 harness had a loose connection (possibly due to me disconnecting the harness several time during the installation process). The harness is a bit complex, but for the most part it was still straight forward to figure out. I am very happy that everything worked well.

Pros: Very well built harness, almost completely plug-in play

Cons: A bit of a tight fit because the wiring harness is a bit bulky with all the extra connectors attached that are not need for this truck.

Terrible. A professional installer couldn't retain the steering wheel functions at first. After 6 calls to tech support and several extra hours of labor, a master reset was required as well as numerous re-flashes.

Just a complete fail of a product No labeling what so ever on the wiring, No instruction hey dig thru 200 plus pages for your vehicle, then lets cram a picture of the stereo harness box and connectors on a one page picture again with no distributions of what the wires are for. Not even worth my time calling anyone since i spent the last 8 hours plus 2 hours in driving because you need a windows machine to program anything. Oh yeah BTW there isn't even enough connection to connect all the connectors from the harness Which is what I suspect is the issue and why only half my steering wheels controls work. Party mode doesn't work, parking assist doesn't work and half the controls. Oh lets not forget that the option for the heated seats isn't working either. Interesting. Sorry Crutchfield back in the day you guys rocked but I noticed you really short cut now by not including what you did in the past diagrams etc etc for that you will be receiving a RMA for the equipment

Pros: none

Cons: it doesn't work as advertised

Verified employee purchase (What's this?)

This came in an installation kit with the ADS-MRR interface module. Although it's intimidating at first glance, it makes installation much easier, and best of all, everything works. For my particular vehicle, the backup camera feed didn't interface with this kit, but it should work for most Toyotas. Also, it would have been nice to have an adapter to be able to use the factory "shark fin" antenna for satellite radio rather than having to use the magnetic antenna that comes with the SiriusXM kit. Although Crutchfield doesn't sell such an adapter, I was able to get one from another vendor.

Pros: Makes installation much easier.

Cons: It would have been nice to have an adapter that allows use of the factory satellite antenna rather than having to use the magnet antenna in the SiriusXM kit. The backup camera harness doesn't work with my vehicle.

Everything you need to get your aftermarket radio installed to your factory wiring.

Pros: Almost plug and play

Cons: No labelling for what each set of cables are for. PDF file that you download off the website with directions on how to hook it up is over 200 pages. It had every single vehicle and there wiring diagrams. You have to find your vehicle then print it out. Which ended up being 3-4 pages

Q
iDatalink Maestro RR has a Pink Cable for Vehicle Speed Data but I can't match it on my Pioneer DMH-1500NEX wire harness? Any idea to use this cable properly with the unit in combination with iDatalink? Or I need to skip this cable? If I skip this cable probably I will not have the speed gauge information on screen correct?
[ mrjtorres  May 30, 2019 ]
1 answer
A
The Vehicle Speed sensor wire is one that helps a receiver's built-in GPS setup work better so the GPS can track your position when it cannot see the satellites to triangulate your location. So, it's not going to hurt anything that your Pioneer does not have that as an input and the Pioneer will still be able to get all the data for the performance gauges without that wire being connected My Bio: https://www.crutchfield.com/bio/Paul

Q
Will this allow me to use the factory back-up camera in my 2011 Tacoma? Now the camera displays in the rear-view mirror (tiny), and it would be much better if it rendered in the touch screen Kenwood stereo I want to get.
[ Chip  Nov 21, 2018 ]

A
I was able to make the camera work in my touch screen stereo but I had to buy a camera wire, cut off the end, and splice in an RCA plug to the camera input on the back of the head unit, so it would plug into the input onto the head unit. It can be done but it's not a simple plug and play. Hope this helps, sorry I don't remember more I did it 2 years ago. Good luck
[ Susan  Dec 13, 2018 ]
A
you will also need the module to run your camera and other factory features. This is just the wiring harnesses for it. The module is sweet though, it will give you truck data that you dont even get with your factory readouts in the dash like tire pressure for each tire and all of the temperature sensors.
[ Robert  Nov 22, 2018 ]
A
Yes. I kept the Sienna camera in the original display (tiny) and added another camera that displays through the 7" screen. I could have just sent the original camera to the larger display.
[ tedpas  Nov 21, 2018 ]
A
I'm certain it is possible. But when I did this install in my 2012 Tacoma I didn't find the video cable anywhere in the dash harness. So I kept the factory rear view camera in the rear view. I did add a front facing camera though, and programmed one of my steering wheel buttons to activate the camera when pressed and held.

Q
I see that the main harness plugs into the aftermarket stereo and has bare wires on the other end. Is there another adapter that accepts the bare wires so that it can plug into the factory radio harness? Is this harness included if so?
