Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles

Great item. Purchased for 2005 Toyota Sequoia with JBL. I have a pioneer aftermarket radio. I tried to get the steering wheel controls to work with posi-taps, but was having no luck. I installed this adaptor and they worked right away. I saw where some people used posi-taps, but Metra says not to use them and I read that by using taps, you're adding resistance to a resistance based system. So I decided to try this as a last resort, and it worked. Plugged right in to the Metra Axxess SWC. The connection to the Toyota swc plug was a little tight, but just force it together.

My 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.

My car is a 2007 Rav4 Limited Edition. I purchased this to preserve the steering wheel control functions. With respect to the OEM controls, I can still adjust volume, go to next folder go to previous folder (in my case, going to next song or replaying the last song), hang up calls. As far as making calls, it will only call the very last person that I spoke with, if I press the "unhook" button. In order to make a call to the correct person, I have to use the features of Android App. The installation process wasn't totally easy, but doable. Fortunately tech support was pretty good. I'm pretty happy with this purchase, and after about 3 years now, I've not had any complaints, problems.

Please note, you must also purchase and install the Metra ASWC-1 steering wheel control interface to make this work. I installed the Metra ASWC-1 steering wheel control interface with the Metra 70-8114 Steering wheel control wiring harness to my 2005 Toyota Highlander with the JBL sound system, also using the Metra 70-8113 ASWC wiring harness and the Metra 99-8206 DIN Head unit bracket system for the after market Sony BT4000P Bluetooth audio system. You have to solder four wires for the main wiring harness, but the steering wheel control adapter is just a matter of plugging in the connectors. Every steering wheel control function (Mode, Volume and Selection which changes station in radio more or tracks when in CD or using iPod). The really wonderful part is that this combination utilizes the JBL external amplifier, bringing a hugely dynamic, full, rich sound to your system that you never knew existed! I am really quite pleased with all of the Metra products. IF you have the JBL sound system, do not forget to solder the blue and white wire from the Metra 70-8114 ASWC wiring harness to the red power wire, as this provides the startup signal to the JBL amplifier when the head unit power is turned on. USE ALL METRA PARTS and you will not go wrong!

This part came new in the package, and had the correct part number label on it (70-8114). However, when I opened the package, the connector on the vehicle end is the wrong one. It was not the Toyota 8215 shell 20-pin connector which you actually need, and did not look like the connector in the product image on this site, either. I ended up splicing the three wires from the steering wheel control harness instead, since I didn't want to waste time or money by trying to replace this connector in the hope of getting the correct one next time. This part is worth less than it would cost for return shipping to Amazon, so I guess I'm stuck with it.

Can't say anything particularly good or bad about it. It's thoroughly average in every way. Nothing remarkable. After using for a while.

Used Successfully with the ASWC-1 on a 2005 Lexus ES330 Sedan without Mark Levinson audio; with AM/FM/in-dash CD changer. I got raid of the harness that came with the ASWC-1 and used the 70-8114 in its place, wired it per the instructions, and it worked. It made the job a lot easier since I did not have to splice into the car harness wiring. In my application, i connected the 3.5mm jack to the Pioneer AVH-1330NEX . I did not need the RCA cable in the 70-8114, so I removed them from the harness. This Metra 70-8114 eliminates the need to cut & solder wires for the car steering wheel harness . It also requires power and ground connections from the radio harness. The connector for the factory harness snapped into the ES330 steering harness easily. All worked as expected.

Was the perfect fit. Plugged right into the interface and into the vehicle harness.

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.

Cut up to work for my application but made it easier and cleaner than cutting up the factory vehicle wiring so it’s reversible and price was right. Steering wheel controls work great!

Wiring is a bit confusing

Does not work with Sienna 2009
