## Overview

The Metra 70-8114 Steering Wheel Control Add-On Harness is a precision-engineered solution for select 2002-2015 Toyota, Scion, and Lexus vehicles with 20-pin connectors. It enables seamless retention of factory steering wheel controls and the factory 3.5mm AUX jack when installing an aftermarket radio with AUX-In capability. Designed for plug-and-play installation, it requires the separately sold Axxess SWC interface and includes RCA connectors for full audio integration. Backed by expert tech support, this harness ensures a sleek, professional upgrade without compromising your vehicle’s original control features.

## Description

When installing an aftermarket radio, the 70-8114 will allow the user to retain the factory-installed steering wheel controls without having to splice into the factory wiring (Axxess Steering Wheel Control Interface is REQUIRED and sold separately). In addition, we included RCAs to allow the user to retain their factory-installed 3.5mm jack. Aftermarket radio must have an AUX-In. This is an optional harness. The main power harness is still required.

Review: Highly Recommended - Read This for Important Installation Details - 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.
Review: Steering Wheel Control for Lexus GX470 No Axxess Box needed, No complicated programming. - 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!

### ⭐⭐⭐⭐⭐ works for a 2005 Lexus ES330 Sedan without Mark Levinson audio; with AM/FM/in-dash CD changer.
*by E***. on March 25, 2018*

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.
