It preserves factory steering wheel controls and the 3.5mm jack functionality via included RCA cables, requiring an aftermarket radio with AUX-In and the separately sold ASWC-1 interface. This harness offers a plug-and-play solution backed by expert tech support, ensuring a flawless upgrade experience without splicing or guesswork. ## 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 (ASWC-1/AXSWC 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: Was the perfect fit. Plugged right into the interface and into the vehicle harness. Review: 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. ## Features - For vehicles with a 20-pin connector only - Retains factory steering wheel controls - AXSWC or ASWC-1 required and sold separately - RCAs included to retain the factory-installed 3.5mm jack - Aftermarket radio must have AUX-In - 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 | | Brand | Metra | | Cable Type | Auxiliary | | Connector Type | aux,rca | | Customer Reviews | 4.2 4.2 out of 5 stars (1,156) | | Global Trade Identification Number | 00086429230822 | | Included Components | Toyota 20-Pin Steering Wheel Control Add-on Harness with RCA | | Item Dimensions | 20.3 x 11.4 x 1.3 centimetres | | Item Type Name | Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles | | Item Weight | 14 g | | Manufacturer | Metra Electronics | | Manufacturer Part Number | 70-8114 | | Material | METRA 70-8114 Toyota(R) 20-Pin Steering Wheel Control Add-On Harness with RCA | | Model Number | 70-8114 | | UPC | 086429230822 | ## Product Details - **Brand:** Metra - **Connector type:** aux,rca - **Item dimensions L x W x H:** 20.3 x 11.4 x 1.3 centimetres - **Item weight:** 14 g - **Material:** METRA 70-8114 Toyota(R) 20-Pin Steering Wheel Control Add-On Harness with RCA ## Images ![Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles - Image 1](https://m.media-amazon.com/images/I/613kTFCS0zL.jpg) ![Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles - Image 2](https://m.media-amazon.com/images/I/61N1Fhju28L.jpg) ![Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles - Image 3](https://m.media-amazon.com/images/I/71Ovrk49zaL.jpg) ![Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles - Image 4](https://m.media-amazon.com/images/I/61skSsNo1ZL.jpg) ![Metra 70-8114 Steering Wheel Control Wire Harness with RCA for 2003-Up Select Toyota/Scion/Lexus Vehicles - Image 5](https://m.media-amazon.com/images/I/81Frw8mpr1L.jpg) ## Available Options This product comes in different **Customer Package Type, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***. on 30 September 2025* Was the perfect fit. Plugged right into the interface and into the vehicle harness. ### ⭐⭐⭐⭐⭐ Review *by S***L on 20 April 2026* 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 *by M***Y on 14 January 2020* 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! ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/136074313-metra-70-8114-steering-wheel-control-wire-harness-with-rca](https://www.desertcart.gr/products/136074313-metra-70-8114-steering-wheel-control-wire-harness-with-rca) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-06-02*
