It enables seamless retention of factory steering wheel controls and the original 3.5mm aux input when installing aftermarket radios with AUX-In capability. This harness eliminates the need for splicing, ensuring a clean, professional installation backed by dedicated tech support. ## 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: 2004-2010 CE / LE. Stereo replacement. This is the plug you are searching for. - 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.

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.com.sa/products/291485171-70-8114-steering-wheel-control-wire-harness-with-rca-2003](https://www.desertcart.com.sa/products/291485171-70-8114-steering-wheel-control-wire-harness-with-rca-2003) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-17*
