I tried using this with my aftermarket radio to make the steering wheel controls work, however I could not get it to work. Have to return the product unfortunately.I used this product to install steering wheel controls for an aftermarket stereo. I’d recommend double checking the stereo you try to connect it to is on the list of supported brands you can find on their website. Some generic stereos (like the ones found on Amazon or eBay won’t work with this). It’s a simple plug and play. Great buy overallMy wife has a Lexus GX470 Non Nav / Non Mark Levinson Sound system. I replaced the factory head unit (Pioneer) with the Binize 10.1 inch Android HU. I got the Metra TYTO-01 kit to connect the new HU to the factory wiring harness, but the steering wheel controls for the GX470 (and likely the Toyota 4-Runner) are on a separate 20 pin plug that goes to the factory HU. Thanks to another user's review here, I was able to connect the Android (which has a SW1 and SW2 Wire) to the factory harness. Here's an excerpt of how to do it from the other user's review: For the 6 wires on the white connector, 3 are of interest. Black wire = GND (connect to GND wire of the new headunit - this is steering wheel controls GND not the main GND - you still need to connect the main ground of the HU). Green/yellow = SW1 / KEY1, green/black = SW2 / KEY2. With this, was able to get the steering wheel controls working with a new Android HU, easy as can be. (End Review)From the Binize Android Head Unit, you go to the settings page and there is a button (scroll down) on the left side that says steering wheel settings. Go in there and you will see various settings (eg. Volume Up, Volume Down, FFWD, RWD, GPS, etc.). Select the desired function onscreen and then press the steering wheel control button that you want to perform that function. I programmed Vol + Vol- Next track, Previous Track, and for the mode button I selected GPS (for which I have Waze set as my default GPS Navigator). The steering wheel controls work great and my wife is thrilled!I installed this on a 2007 Toyota Solara, with a Pioneer head unit. This is a great product, but you must also purchase and install the Metra ASWC-1 steering wheel control interface to make this work. I connected the wires from the white connector to the car stereo wires, and in most cases it was a simple color match, but make sure to check your specific wiring diagrams. The white connector on this harness connects to the car's steering wheel connector (formerly on the factory radio). Don't worry about which plug it goes into, because Toyota has made all the connections to their car stereos different, so this will ONLY fit on the steering wheel connector. The male 3.5 mm plug then goes into your new car stereo's wired remote input jack, typically on the rear of your head unit. Next, here's a very important point that no other reviewer has provided, and when I called Metra, they actually gave me the wrong answer - if you connect this harness, you DON'T need to use the connectors/harness that comes with the ASWC-1. Once you connect the white connector of the 70-8114 to the car's steering wheel connector, and the 3.5 mm male plug to you car stereo, you then plug the black 12-pin connector (shown in the lower left of the picture) directly into the ASWC-1 (purchased separately). One connection/plug to the ASWC-1 and you're in!! In my case I then turned the car key to the accessory position, powered on the radio, watched the LEDs on the ASWC-1 go through their initialization, characterization, and setup, and within 15 sec or so I had the steering wheel controls working - volume, up/down channel, and mode select. Works perfectly! Another lesson learned in my case was that the power antenna cable from the stereo needed to be connected to the blue cable on the 70-8114 even though my Solara doesn't have a power antenna (antenna is in windshield), it turns out that the Solara has an antenna amplifier that needs to be switched on with the stereo. Once connected, the antenna (and FM reception) was as good or better than the OEM radio. I highly recommend this 70-8114 harness along with the ASWC-1 for Toyota vehicles, when replacing an OEM car stereo.Amazons “guaranteed fit” guide for your vehicle is wrong. Amazons fit guide said this wouldn't fit my sequoia. I looked at multiple websites that said the same thing until I went to another website (crutchfield.com) that said it would fit. So I took the chance and bought it knowing of it didn’t fit I could return it.Sure enough. IT FITS my 2013 Toyota Sequoia without JBL/Navigation. My only complaint is you have to try and figure out which wires on the factory harness are the power and ground wires to splice the axxess harness too. The instructions online don’t tell you.This was almost plug-and-play. The included instructions were easy to follow but didn't elaborate on the needed supplies to splice the power and ground wires to the existing harness. With a little youtube and google research, the solution was found and easy to accomplish. Not having to figure out the colors needed to plug into the harness made the installation simple after the splicing was completed.Turns out these are really made to plug right into a Axxess SWC1 controller. I didn't need that but the other plug is valuable. I bought one of these for an Atoto install I just did. I have an 09 Rav4. This Toyota has a 3rd plug that holds all the wires from the steering wheel and the aux and junk. My key was pins 6,7,8 if this 3rd plug. This harness gave me easy access to them without interfering with the oem side of the plug. See the Metra green-yellow for Pin7, green-black for pin 8 and pin 6 black for ground. I patched these through to ground and the Key+, key#+ on my Atoto and my SWC in this old thing work GREAT.Just like it says!Used on a 2005 4Runner. The big white connector plugs into the 4runner factory wiring, which goes to the steering wheel controls. For the 6 wires on the white connector, 3 are of interest. Black wire = GND (connect to GND wire of the new headunit - this is steering wheel controls GND not the main GND - you still need to connect the main ground of the HU). Green/yellow = SW1 / KEY1, green/black = SW2 / KEY2. With this, was able to get the steering wheel controls working with a new Android HU, easy as can be.Do you have a basic Toyota Sienna Radio (non-JBL), steering wheel controls (SWC) and a 3.5mm Aux input. Are you upgrading the Stereo and want to keep your SWC and Aux input working? This is the harness adapter you need. On my install I did not use the Metra Steering Wheel Interface (SWI) with this harness. I instead purchased the PAC SWI-RC. I cut off the black Metra plug from this harness and soldered on the correct wires from the PAC interface With the PAC you can change the function of your SWC buttons to perform other tasks. My van only has 3 buttons on the steering wheel, some have 7. For example when programming the SWI I made the mode button control, voice activation. For Apple CarPlay this is Key! One touch Siri from the steering wheel. The other part of this harness is the Aux input, connect the RCA's directly onto your new Stereo, another adapter my be required, and Boom there you go. Seamless install with everything still working.My FJ Cruiser only has the vol up/down, next/prev track, and more buttons. As a result I only needed 3 of the wires from the harness (pins 6/7/8) for Key 1, Key 2, and Key Ground on my aftermarket stereo. After that, I needed to program each button on the steering wheel using the steering wheel button app in the stereo.Got this to work perfectly (with some modifications) with an Atoto A6 Android receiver and a factory 05 Tacoma steering wheel. Fully programmable and works in both android and CarPlay.I tried wiring the AUX with a separate cable and there was always a delay. With this adapter, it allowed me to use the stock AUX port which seems to provide better quality as well as no delay.
