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 allows retention of factory-installed steering wheel controls without the need to splice into factory wiring (Axxess SWC interface required and sold separately). It also includes RCAs to retain the factory-installed 3.5mm auxiliary jack. The aftermarket radio must be equipped with an AUX input. This is an optional harness; the main power harness is still required. Review: Works Great for 05 Sequoia w/ JBL - 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. 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! ## Features - For vehicles with a 20-pin connector ONLY - Retains factory steering wheel controls - AXXESS SWC interface is REQUIRED and sold separately - Includes RCAs to retain the factory-installed 3.5mm jack - Aftermarket radio MUST have an AUX input - A tech support number is available for installation help 7 days a week - For vehicles with a 28-pin connector, please use the AXSWCH-T28 - Please review the Metra Electronics Vehicle Fit Guide for fitment confirmation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0064J4LOM | | Best Sellers Rank | #43,502 in Automotive ( See Top 100 in Automotive ) #109 in Automotive Replacement Electrical Wiring Harnesses | | Brand | Metra | | Brand Name | Metra | | Cable Type | Auxiliary | | Connector Type | RCA | | Customer Reviews | 4.2 out of 5 stars 1,210 Reviews | | Global Trade Identification Number | 00086429230822 | | Included Components | Metra Swc Add-On Harness With Aux-In For Toyota | | Item Dimensions | 8 x 4.5 x 0.5 inches | | Item Type Name | Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles | | Item Weight | 0.03 Pounds | | Item dimensions L x W x H | 8 x 4.5 x 0.5 inches | | Manufacturer | Metra Electronics Corp | | Material | METRA 70-8114 Toyota(R) 20-Pin Steering Wheel Control Add-On Harness with RCA | | Material Type | METRA 70-8114 Toyota(R) 20-Pin Steering Wheel Control Add-On Harness with RCA | | Model | 70-8114 | | Number of Items | 1 | | Part Number | 70-8114 | | UPC | 086429230822 | | Unit Count | 1.0 Count | | Warranty Description | Please contact the manufacturer | ## Product Details - **Brand:** Metra - **Connector Type:** RCA - **Item Weight:** 13.61 g - **Item dimensions L x W x H:** 8 x 4.5 x 0.5 inches - **Material:** METRA 70-8114 Toyota(R) 20-Pin Steering Wheel Control Add-On Harness with RCA ## Images ![Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles - Image 1](https://m.media-amazon.com/images/I/613kTFCS0zL.jpg) ![Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles - Image 2](https://m.media-amazon.com/images/I/61N1Fhju28L.jpg) ![Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles - Image 3](https://m.media-amazon.com/images/I/71Ovrk49zaL.jpg) ![Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles - Image 4](https://m.media-amazon.com/images/I/61skSsNo1ZL.jpg) ![Metra 70-8114 Steering Wheel Control Add-On Harness with AUX Input - Fits Select 2002-2015 Toyota/Scion/Lexus Vehicles - Image 5](https://m.media-amazon.com/images/I/81Frw8mpr1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great for 05 Sequoia w/ JBL *by S***L on April 20, 2026* Great item.

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. ## Frequently Bought Together - Metra Toyota 20-pin Steering Wheel Control Add-on Harness with RCA - Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker - Axxess AXSWC Steering Wheel Control Interface --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/1593356-metra-70-8114-steering-wheel-control-add-on-harness-aux](https://www.desertcart.com.ar/products/1593356-metra-70-8114-steering-wheel-control-add-on-harness-aux) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
