You are a big money and lifesaver! Thank you so much for this video. Changed my HU to a Pioneer one in my volvo and thanks to you I got the original steeringwheel buttons to work again. Awesome!
Hey did you happen to have a volvo semi truck or car? I'm trying to wire my buttons on my volvo semi
@@karrar55 i did it to my 2002 V70 car.
Thanks for the thorough video. Helped me sort out my SWC connections
Great work, thanks for this. I've just put a new Pioneer head unit in my Prado, and did buy an after-market converter for the steering wheel controls. But I was mystified as to how it worked - how so many buttons could send signals over basically 2 wires, one of which is ground! I was even thinking maybe it was serial RS232 data. But now I know - not RS232, but much simpler and very clever. I wish I'd seen this before I did the job.
Thanks! :-) I posted link in my video for others who wanted to know "how", I was not able to explain the details how it works (previously I made just step by step video without any other explanation). Your video is clear and very informative, thank you! :-)
Very useful tutorial! Thank you
Thanks for the great video! You are one of the few people who actually explain how these resistive controls work.
If someone were to design a custom resistive circuit, would you recommend any debounce filtering or would that be unnecessary?
No debouncing needed for those controls
hi, very informative video. Do you know if chineese head unit devices do in the same principle? There only KEY1 (and KEY2) wires, no 3.5 jack for SWC. What voltage they are using?
Fun part is the resistors aren't marked like in the old days are they?
I've wondered how just one wire could control so many functions. It's all because the radio looks for (and acts on) the resistence between the single wire and ground.
Very interesting got all that and understand that!
. Except It doesn't appear to work like that exactly on my 1999 SAAB 93 Aero.
What happens is the buttons are connected to the SID ( SAAB Info Display) and 2 wires called Ebuss plug into 2 pins on what was originally a SAAB branded Clarion Stereo.
As I have a Chinese android with a learn function for the buttons it should learn whatever the resistance for each button is. however putting a meter across it doesn't reveal resistance looking at it with DC volts it jumps around all over the place and doesn't change when you hit any of the buttons( they work with the original stereo) I think it might be data.
Someone on a forum said it was voltage ( which would vary with resistance)
I'm reluctant to just plug the 2 wires in ( not worried about blowing up the stereo but if it shorts out something electronic in the SAAB it's going to be both difficult to find a replacement and expensive.
If it’s voltage you can get what’s called “electronic resistor” it converts voltage to resistance, it’s an IC chip.

Interesting, I just searched that and it looks like you can do it with a pair of MAX5160 digital pots.
I will have to stick a scope on there to try and see what's actually on those lines. If it is data then It will be easier to hack into the wiring elsewhere.
However if it's voltage as suggested in the SAAB forum then the digital resistor approach will likely work
Oh I I too have a pioneer ,an 8500nex to be exact lol that is all and horrid punctuation in my other comment just exited sorry glad I found you lol
Genuinely informative video man, but your diagramming had me flinching. Reminded me of a doctors script haha! Maybe take it a bit slower and dont use so much shorthand when youre drawing something to explain a new concept. Cheers
And then you showed the one at 11:29
That was easy to follow.
I have a Pioneer radio. Will the Sony resistor setup work the same way on my Pioneer?
It depends, check if your pioneer has learning function for the steering control, then any steering control will work. If it doesn’t you can try to see if it’s gonna work as is, if not you’ll need to resolder your steering wheel resistors.
anyone ever find out the BOSS resistances or a schematic?
Fantastic video. This is exactly what i was looking for. Where did you find the Sony schematic? Do you happen to have any resources as to where i can find Information on a given stereo? For example, I just bought a Boss audio BCPA9690RC and really don't want to pay 50 to 100 dollars for a unversal box, but I am having trouble finding any schematics for the remote circuit. Is there somewhere that offers these?
First check if your head unit has a learning function, sometime they have learning function and you can just learn buttons digitally on head unit without any external adapters. If it doesn’t then you can use 2k resistors to probe out what happens, so power the head unit and then short the 2k resistor between the control and ground, see what function it triggers, then 4K then 6k ect (just 2k resistors in series) unfortunately there’s no website that has all this info, you can try contacting the manufacturer and asking them
@@MaxELECTRONICSmy swc dont work with headunit. Swc however work with original radio. Is it a hardware failure, what do you think?. Everything is connected correctly. It worked but uddenly broke down.
Check if there’s a termination resistor permanently installed between ground and signal cable
@@MaxELECTRONICS thanks for your comment. I'm not sure what it means However only modifiacation to the previous system is an amp connected to the factory ground. Swc worked with the amp until my first drive when it stopped suddenly. I thought that could be a capacitor or something alse etc in HU.
It’s hard to tell without looking at it.
I got one for you ,the 2017 Dodge charger / Challenger steering wheel I've got it apart in front of me 😖
Does canbus make a difference or can I just wire it up may I add it's a bit of a project as this is going on to a stratus /eclipse ,which is funny because your exact steering wheel is why I'm doing this there's a writeup on club3g about upgrading well I figured I stead of the steering wheel you have Ior outlander , would use this one a 2015-17 dodge wheel out of a challenger I know this is doable just not sure where to start looking or who to ask to further my education 😖,thank you for you time brother 😊I'm going to watch you video for the 20th time and continue attempting to apply it to mine thank you again 😊
If you have an aftermarket unit but steering is canbus (it’s unusual) you can just use the wire to connect to the unit and on the steering wheel side just rewire buttons to resistors and connect to the wire that’s going to the headunit
Thank you for the timely response!
You know what I was thinking the exact same thing ,but beings the wheel is out of a canbus vehicle I wasn't aware that we could just wire them the same way oh wait ok ok,I see what you are saying ok I misunderstood you ,you know what that is worth a try for sure thank you ,I did get everything disassembled before and it is a quite bit different then mine or your wheel I think, I wish I could show you 🤔 ... at least where I should solder at I wish I had someone to vet that , it looks more like a motherboard now then a circuit board. The unless you want to try and do a video on playing around with that wheel haha mabey hooking it up to your vehicle I think youd see what I mean I'm going to try what you said tho I'll keep you updated thank you for the feedback max I really do appreciate it !!! Watch it be this simple haha as someone who tinkers with stuff too it's in my experience that once the project is over and your looking back, it's usually us that makes it more difficult then what it was haha thanks again !!!
Hello, for Sony DSX-A200 car stereo does this same configuration of resistors work?
Yea all Sony resistances are the same, you can google “Sony steering wheel resistors” and click images, you’ll see them.
So I'm assuming the seek buttons work as track up and down on the USB and cd player(if equipped)?
Yes they would be
I drive a honda civic 97 model.
I want to install a honda accord steering wheel with a button function and I want to install a 9ich touch screen. Will it work or is there a way to make it work on a car like mine. Thank you.
Yes, the touch screen will have learning function that can be programmed to work with any steering wheel
Hello, where dit you found the schematic? I need to found this kind of schematic with resistor for a JVC radio! Thx!
Just online in Google

My Mazda steering controls seem to work backwards. I have not analysed the circuit, but based on my multimeter readings: no buttons = 5KΩ, then it drops off depending on the button: mute = 2KΩ, mode = 1KΩ, down = 550Ω, up = 300Ω, vol+ = 150Ω, vol- = 55Ω. I think I need to somehow reverse this so no buttons = no resistance, then it adds resistance on pressing of buttons.
You can remove “termination” resistor, some steering wheels have termination resistors that complete the circuit, they usually required for OEM head units.
@@MaxELECTRONICS I'll check the board and see. Your video is excellent by the way thank you.
My Chinese import headdeck has programmable button inputs, and I managed to get it working without removing the termination resistor. I needed to put one of the wires from the steering wheel to ground, and the other to one of the SW wires from the head deck, then programmed the 5k resistance to "none" button, and all works perfectly!
On my ford transit there is no cable in the harness for the steering wheel controls. The BEMM manual (body equipment mounting manual) says there should be 2 pins for steering control. They don’t exist in my van so how would I go about testing which wires input steering wheel controls into the radio?
If you don’t have any cables in your steering wheel you’d have to buy the “spring cable” that goes into steering wheel. Then you’ll be able to connect the buttons.
@@MaxELECTRONICS I’ll have to have a look inside my steering wheel, there are buttons that controlled the OE radio (skip/rewind track, volume and voice recognition). There should be cables into the harness in theory but I can’t fathom why they’re not there and how the radio previously operated perfectly 🤯
@tomloweshow you can have a look at the datasheet of the current radio you have and see what pin is remote. Or you can open steering wheel and check for continuity with multimeter
Hey Max. Awesome vid. I’m having issues with a Sony in a gen 1 Mini Cooper. I bought the control module adapter but it’s intermittent.
Found your vid and curious: the Sony (MEX 5300) has programable functions. Like mapping a game console controller on PC. You select the function on the head unit and it prompts you to press a button on the steering wheel. Is it safe to assume I would just need to directly wire my steering wheel leads to a 3.5mm Jack and the Sony head unit would map based on resistance and as such no need to solder resistors?
Is this also applicable for Kenwood DDX model?
Yea, just different resistances, I’m sure you can Google them or just Rey with different resistor to see what function it turns on
Sigh...if only this hack would work with the Clarion ARX8370R I'm putting in my 2011 Fusion.
Very informative, too bad you didn't show you built the cable.
Does this apply for touchscreen radios? Same principle?
Yes it is :)
Hello my friend.If i have two different key line wires like key line 1 and key line 2 is it possible to connect to the same multimedia unit 2 controllers ???One controller the steering wheel controller and the other an i drive controller behing the gearbox.Will it work???
The second one is most likely data, it usually connects to the stereo with iLink adapter (if your stereo supports iLink)
@@MaxELECTRONICS what do you mean iLink???The key line 1 is for controller and the key line 2 what for???
@@MaxELECTRONICS So in key line 2 wire isn't possible to connect a second controller for the multimedia except the one i have on steering wheel ????I want to connect an bmw i drive controller if you understand what i mean
@giorgosc4298 if it’s just going to steering then it’s for answering and hang up buttons, it’s used with diodes and connects to line one
U have Techno MP5 Stereo. And it has a wire in harness that say Steering Wheel/IR-Out. So how can i make my steering buttons work with that. Please help me out
Did it come with manual?
@@MaxELECTRONICS No. no manual.
If i can show u pictures. Maybe than you would get it and be able to help me out.
Hello. Please help me choose the resistance for the Clarion nx + Mitsubishi steering wheel.
You need to find service manual for your stereo and have a look at the resistances, or you could buy “programmable resistor” and try different values in increments of 1 kOhm and write down the values. For example try 1k and see what happens, then 2k ect
@@MaxELECTRONICS I didn't find the necessary information in the instructions. Google doesn't find it either. I tried the selection method, it doesn’t respond.
I'm way lost :( ..can't follow this level of technical. Who can follow this
Hey mate, just wondering if you have a link to the Pioneer wired remote resistor network diagram you have in your video, unfortunately it is unavailable on the JVDE website anymore. Have been searching got either that or a similar reference, sadly to no avail. Kind regards, Damien
Pioneer has exactly same resistance as Sony so follow Sony one and it will work with pioneer
@@MaxELECTRONICS Many thanks for your speedy reply! Now if I can only find the resistance for the voice command button! :)
