Learn how to install a steering wheel control adapter

One of the problems with replacing your factory radio with a new receiver, is that those handy audio controls built into the steering wheel won't work anymore.

The way to solve this dilemma is to install an adapter for the steering wheel audio controls, which we offer at a discount when you buy a compatible stereo. In this video, we'll walk you through what's involved in the installation process.

Installing a steering wheel audio control adapter | Video Transcript

When you install a new stereo in your car, you lose the benefit of these — the handy controls built into the steering wheel. That's because those are wired for the factory stereo and you can't just plug it into the back of the new stereo.

But what you can do is install a special adapter like this one, and that's what we're doing today. This adapter lets these controls interface with the new stereo so that you can use them just like you did before.

Plan the wire connections
I did my homework for this installation and downloaded instructions directly from the Axxess website. On their site, you tell them what kind of vehicle you have and they'll tell you right up front whether their adapter works with your car. And from there it's step by step, wire by wire, what you need to do for the installation. I added the color coding just to help myself out a little bit.

Disconnect the battery
I've disconnected the battery and I'm getting ready to pry open the dash panel so I can get the stereo out. That's what this puppy's for. Disconnecting the battery is important, and I want to note, for two reasons. One, I don't want to risk shorting something out so that my dash lights or stereo or A/C doesn't work. And two, there's an airbag sensor in this console and I don't want to mess with that, so I'm doing the job right.

Remove your stereo from the dash
I popped off the top panel, then removed a couple of screws and pulled off the main dash panel exposing the radio. Then four more screws out from the side of the radio and it's free. Now I can get to all the wiring. Next I'll take a look at the adapter. Opening the package I found the instruction manuals, a couple of wiring harnesses, and of course the adapter itself.

Connect the adapter harness and your stereo
At first glance, this harness looks a little intimidating, but don't be afraid of it. You're not going to use all these wires. First, you'll have your power and ground, naturally, and then depending on your vehicle, you'll use one or two of these wires to connect. For example, my car will be using these two. The rest aren't used and I can just tape them up or cut them off, whatever I want to do.

That leaves this big black cable. This is the control cable that'll plug right into most stereos. Now mine is one of the brands that doesn't work that easily, so instead they include this adapter. I plug that in here and then connect one of these two brown wires to a wire that's already on the back of my stereo. Not that bad.

Re-install the stereo
I used Posi-Tap connectors to make all the wiring connections between the adapter harness and my stereo. And now I'm going to re-install the stereo. So I plug this back in. And here's our new adapter and it's harness. Plug this guy in, there we go, and get that down there where I can reach it in a few minutes.

Programming the steering wheel control adapter
Alright we've finished installing the stereo and the adapter, the dash is back together, and I've pushed the adapter out through the bottom of the dash so I can see it, because the next step is programming the adapter. It needs to know what kind of car it's in and what kind of stereo it's connected to. So to do that, I turn on the ignition and watch for the Axxess adapter to start flashing. Once it does, following the instructions, I hold down the volume button on the steering wheel and just wait as it runs through its paces figuring out everything it needs to know. And once the adapter's LED is on steady — no longer flashing — then it's done. After that it's a matter of testing the buttons to make sure they work. And they do.

And that's how you install a steering wheel control adapter. It took a little planning up front and being prepared, but it really wasn't that hard. I chose the Axxess adapter because it was able to program itself on its own, meaning it could figure out by itself which buttons on the steering wheel controlled which functions of the stereo, and that made the process a little easier.

Sometimes it's not able to figure that out, and you have to do it manually, so you have to go in and say "This button controls tracks. This button controls volume up, etc." Instructions for doing that are included, and it's not that hard. It's just another series of steps.

So here's the adapter at work changing volume on the disc. I can change tracks. It'll also let me go through sources. I'm really excited to have these buttons working again, and if you're going to do this in your car I strongly recommend you install the steering wheel adapter at the same time you change the stereo. It'll just save you a lot of work. When you're ready to do it, give us a call. Our advisors will make sure that you get the adapter that works with both your car and your brand of stereo.

    I bought a adapter from Walmart. How do I program it to get my controls working?

    Robert Ferency-Viars from Crutchfield on 12/14/2018
    Jackie, your best bet is to visit the manufacturer's website or call their customer service number. The adapter is their product and they'll be glad to help you with it. You can purchase Crutchfield Tech Support (90 days of support for $30), but if the adapter is a brand that we don't carry, then our help might be limited since we're not familiar with it. If you're interested, check out our tech support page for details.

    Sure looks easy reading this. Nothing about broken dash pieces, bleeding hands, or not having enough room to get everything back in.

    The instructions for the ASWC-1 Steering Wheel Control that I ordered from you guys specifically say NOT to use taps or barrels, as they add resistance.

    Robert Ferency-Viars from Crutchfield on 11/20/2018
    That's a fair point. Garrick. Those warnings were mostly intended for older-style taps and crimping. There is no doubt that soldering yields the most secure and best quality connection. And by all means, you're welcome to do so. We've used Posi-Tap connectors when installing steering wheel control adapters for years without a problem. Just make sure that wire is secure in the barrel of the Posi-Tap (doesn't pull out), or that your wires are tightly twisted together, before inserting them in a Posi-Connector. And if you're purchasing from us, our Tech Support team is always just a phone call away if you run into trouble.

    Hi, I was wondering if you could help me to find the part number of the cable that connects the 2013 Toyota Corolla OEM steering wheel controls to the OEM stereo system of that vehicle? I have been looking for that cable and have not been able to find it. Thanks in advance for your assistance on this.

    Alexander Hrabe from Crutchfield on 10/1/2018
    Miguel, we don't sell OEM parts, but you might have luck giving your local salvage yards a call to see if you can find one second-hand.

    Alexander Hrabe from Crutchfield on 8/15/2018
    Kaide, I've passed your question along to our team of Advisors. Someone will contact you soon to help find a steering wheel interface that works with your current steering wheel controls. We wouldn't be able to help you with a replacement steering wheel though.

    I noticed in the video, the steering wheel also has buttons for the hands free phone. This will be my case also. If the stereo has that function, will those buttons work as well?

    Terry, I'm not familiar with Ouku, but these are the compatibility details for the the Axxess Steering Wheel Control Interface: It's universal and can be used on your '05 Expedition with factory steering wheel controls. The aftermarket head unit must have a SWC (Steering Wheel Control) 3.5mm input or steering wheel remote control input wire (blue/yellow).

    Von Aspern, our database spans vehicles sold in the U.S., so we wouldn't be able to make any guarantees about your Prius, which, I presume, you purchased in Germany. However, if you believe your vehicle is the same as those sold in the U.S. in the same year, you can use our vehicle selector to see steering wheel control options.

    Marcus, as long as you purchased the correct harness for your vehicle, you should get full functionality from your radio (without steering wheel controls). Retrace your installation steps and recheck all of your connections to make sure they are secure. Any interruption of signal from the radio to the speakers will cause your system to function improperly. If you bought your gear from Crutchfield, you can call Tech Support for free help troubleshooting your system. If you purchased your equipment elsewhere, you can still get expert Crutchfield Tech Support - 90 days-worth for only $30. Check out our tech support page for details.

    Kathie, as we said in the video, we downloaded vehicle-specific instructions from Axxess' very helpful website. So, instructions are readily available no matter where you purchase an Axxess adapter. Although if you purchase from us, you're entitled to free lifetime tech support to help you with installation. For what it's worth, this video is an overview of what it's like to install a steering wheel adapter so that you have an idea of the process, but the details of the wiring will vary depending on the vehicle. Car installations pose their challenges, and the last thing we aim to be is unhelpful. If you have any questions about a product, feel free to call us.

    I have an aftermarket Stereo that i have wired in my ford freestyle that works 100% except the wheel controls. It isn't a name brand, but it does have SWK 1 and SWK 2 wires and in radio settings for steering wheel controls. i purchased a Scosche interface and an axxis one as well and cant figure out what to do.

    Drew, the Maestro should still work without using the 3.5mm jack - you use the Kenwood's blue/yellow wire instead. Don't forget that you need to "flash" the Maestro with the controls for your car by connecting the Maestro to your computer (just follow the instructions that came with it). If you purchased either the stereo or the Maestro from Crutchfield, our tech support team can help. Just give us a call. You can also call iDatalink's tech support line at 877-212-6169.

    I have just bought a Kenwood KDC BT362U H/U and noticed that the 3.5mm jack on the rear is NOT for my maestro, but for the mic for bluetooth. I see the video here shows that the maestro 3.5mm jack must be plugged into the radio wiring harness to function. I have connected red, black, black/white & purple/red wires specific to my 2007 Hyundai Sonata, but the maestro will not turn on. My Kenwood H/U included a light blue/yellow wire for steering wheel remote control, which I also connectd to the H/U harness. So the 3.5mm jack is about the only thing not currently connected, and my reasoning is this is preventing my steering wheel controls from once again functioning. Please advise.

    David, if you want to continue using your Civic's steering wheel radio controls when you install your Jensen, then yes, you'll need an adapter. You can find out which adapter will work with that match of car and stereo on our site by pretending to purchase your VX3010 and a steering wheel control adapter, then delete the stereo from your shopping cart. Frankly, the easiest way to get it is to just call us. Our Advisors can look it up and get you the adapter you need right away.
