- First and foremost I would really recommend this cluster build only if you have some basic level of soldering skills and understanding of electronics since the k-bus circuit needs to be soldered and built. This tutorial has been made as the previous video wasn't deep enough and there has been lot of request from viewers to make a more in depth one. Hope this helps :)
Known working cluster model part nos# 0263606305, 0263606221 & 0263606286
I will be soon posting video of a BMW E90 cluster soon which is much easier to built with just only 4 wires and really easy even for a noob to setup. So, stay subscribed to get latest updates & thank you to all you guys who have subscribed!

My brother, until you did, I love you, the truth is that my project was a bit stuck due to personal issues and work, but your video will save my life. Thank you for the great contribution to the community. I send you a hug from Argentina (by the way I got all the parts to assemble it)
( could you make a video of how to solder the circuit board is that I am very bad with that honestly )
Thank you & glad you liked the video! :)
Hopefully your unit also gets fully functional soon. Umm, a perf board soldering isn't something I can just show to a beginner and you will understand. My suggestion is either watch some nice videos that teach soldering and how to assemble a simple circuit on a board. This will definitely need some practice. You might want to first learn on a breadboard before moving to perf board soldering .Since the electronic traces have to be build manually unlike a printed circuit board, you can become confused easily if you straight go for soldering with trying it on a breadboard.
Or take help from some one who can do it for you like a friend or even an electronics repair shop for a price.
So glad i found this i just bought a e46 speedo!
I also have a Holden VX Commadore dash working which operates basically the same as E36 using Simhub and Arduino Uno, just need to make a few adjustments to max Spd & Rpm to suit then trim revs also use jumper to bypass service reminder if need be.
That's a nice looking cluster
Looks like you can use an old Toyota or Honda Audi Speedo too. But the newer digital displays will be harder.
The newer clusters with analog gauges fully CAN have only 4-6 wires and are easy to setup for someone who knows about coding and electronics like example BMW E90.
Yes, you are right with the digital. It’s difficult but doable I guess. But would require a lot of work I assume.
You solve my big problem! (VW Polo 6R)
Excellent video!
I run an E36 dash on my sim.
Cool, thanks! The E36 & 46 clusters are my all time favorites along with the Panamera 970.
Thank you for adding further explanation. I am probably going to do this build with a student. Is your fuel tank empty in the game or you haven't yet made the fuel gauge to work. Cheers from Bulgaria.
If you look at the original circuit diagram and setup, the fuel gauge stepper motor has been replaced with a servo motor. Which is then connected to the arduino. In my case I didn’t modify my gauge as I intend to sell it off later.
The original gauge setup in the cluster works depending on the change in resistance value when the float operated in the tank. The resistance values can be found at the bottom of the below page:

Hope this helps.
Really apreciate your answer !
We will try to build this in the upcoming month.
@@randomscience4k Are you willing to give me a hand with something ? We managed to get the speedo to work - but that's all. I the other E46 video I saw an ignition key and I feel like this is the thing that we are missing in order to make the cluster work.
Nevermind the ignition - found it in the comments - it is connected - pin 4,5,6 on black connector.
Came to the conclusion that it is actually the libraries which cause problem because communication works.
Helpful video, i did everything but turn signals and other lamps are not working.I pasted custom protocol in simhub and did everything like un the video.
I also tested the cluster (secret menu) and every lamp works fine
Hi, some of the warning lamps are driven by can and they should work fine. The turn signal and non warning lamps are driven by the k-bus circuit. Is the k-bus circuit correctly wired?
@@randomscience4k Thanks for the reply. I also think that it might be a problem in my k-bus circuit. I will redo it and update you.
@@randomscience4khi, still cant find where the issue is. My k-bus circuit seems to work,because i unlocked a bmw radio with it . I read somewhere that the problem may be clone arduino,so i will order an original one.
@@georgimilev6786I see, thanks for the update. Let me know how it goes. BTW there are some members in the channel's discord group who have simrigs based on the E39 and E46.
Hey there. What kind of signal does the E46 speedo use? I want to generate the signal using arduino. Im actually on m54 swapped E36 project, so I want to use the original E36 signal to run my E46 dashboard's speedo. Thanks!
Hi, the speedometer on the E46 is just like the E36, it’s PWM signal driven. Don’t know if it will work directly with that E36, but you can always try.
Many thanks buddy😊😊. I will it later this afternoon. Regards!!
Okay this video really helps alot! I bought a cluster from a e46 Diesel and wanted to just mess around with the can bus (since I made my gaming setup out of a complete dash from a different car) but for some reason the data doesn't reach the cluster. Does there need to be a 120 Ohms resistoe between Can H and Can L? The cluster powers up fine but no can communication works and the temp gauge always goes to maximum
Happy to hear the video is helpful. You do not need to add any resistors. Which shield are you using? Generic or something from Seeed/spark fun etc?
@@randomscience4k I am using a Keyestudio Can Bus shield (some cheap shield that works with any cluster but that one). Idk maybe I set the bitrate wrong tho. Currently have it set at 500 KBPS and using addresses from the internet but there's no response from the cluster. Or do I actually need the K-Bus to get that to work at all?
@@vampyryannik7334 Sorry for late reply. The K-bus is only for certain lamps. Try to use the default send code in can bus library and see if the Arduino initializes on the serial monitor. I see from aliexpress pictures that the board does not have a 120 ohm resistor by default.

I had initially ordered a simple Chinese one off eBay and for me it worked fine, but mainly the issues I faced was something else.
@@randomscience4k it's totally fine! I actually found the issue lmao and now it works fine. I aswell managed to get every warning light off, except the parking brake which does not dissapear when I hook it up to Ground or 12v.
@@vampyryannik7334 what was the issue? my temp is stuck at max and my tachometer does not work.

You need the correct can bus library
@@randomscience4k i ordered the can bus on amazon can you tell me which one i have to use
great video. i followed everything and got most of it working. speedo works but the tach only works when the game is paused. any ideas as to why. i have another gauge cluster open when trying to make it work
Thank you! Glad the video helped you to get your unit running :)
I too faced the same issue with RPM. The only fix I could do to get it to work was to open a dash and keep it running in the background to get RPM to work fine. I’ve explained this at time stamp 22:19.
@@randomscience4k thats what I meant when I said I have another gauge cluster open. Nothing has worked for me still.
@@mr.hankie same problem with my cluster too!
I have all the pieces but the only thing that has me stuck although I think it's a joke is the circuit of transistors and resistors that you have to assemble 7:10 I tried to assemble it once following the photos in your video but I couldn't and I can't read the diagram I don't know what's wrong with me.
It’s something unfortunately you need to figure out..Btw the OG code has undergone some updates. Check the pinned comment please.
Thank you so much for this helpful video, i made it to the point where i can control the cluster via SimHub. However the cluster only displays RPM and Temp for 4 to 5 seconds before returning the RPM back to 0 and Temp to maximum.
When i try to set the baud rate of the arduino to 230400, the arduino contantly loses connection to SimHub. When i set the baudrate higher or lower the connection to the arduino is good but the RPM and TEMP only work for 4 to 5 seconds.
Can you maybe help me?
Thank you! Glad you found it helpful. I too found this issue and couldn’t exactly pinpoint what is causing the issue. A workaround I found was by opening one of the preloaded cluster dashboards in SimHub and allow it run in the background. At time from 22:20 to 22:40 I've explained about this.
did you ever figure out the switching off issue, kevin?
Do you think this would be possible to get running in a more sinple way using an Arduino UNO or is the extras of the Mega a need?
You need a mega itself I think..get a clome so it's cheaper
Hello, I am building a simracing with an e46 dashboard (I have photos and I will upload the process to TH-cam). and I want to make the cluster work, do you have photos or something more detailed on how to assemble the arduino, the resistor board, transistors, etc?
Or if you would pay yourself? Thanks a lot!
It's super cool what you've done :)
Thanks! I didn’t show anything related to Arduino is because the details are on Neuro Projekte website linked in description. It’s in German so you need to use Google translate if you wish to read. But the code, ncalc and wiring diagram are in English. BTW this project will require some good knowledge of electronics and soldering skills. The circuit itself is easy if you are good in both these. Even if I soldered it wouldn’t be economical to ship it off from Saudi Arabia where I’m currently working now. Shipping costs from here to other countries are very high.
@@randomscience4k Ahhh okay, I thought you lived in Europe, I'm a mechanic but not an electronicsman, I know electricity in vehicles but not at this level... welding is not the problem, I have visited your page but nothing is clear to me... I sent you several emails but I still don't have an answer from you :(( In the end I am forced to put an e36 cluster that is easier and there is more help on the internet :(
Hey buddy. Great video except for one thing. I followed every step, bought everything part for part for part. Followed all steps on simhub but unfortunately nothing. Yet when I use the original code from the German site it works straight away. Any advice to get your code to work would be greatly appreciated. Thanks
Hi, sorry for the late reply. The code on my google drive link is 99% same as the original German one except for the fog lamp indicator active. That's the only difference.
Hey I have a 1999 Ford ranger speedometer it doesn't have pins on the back just different hmm 🤔 he had pins to connect the wires
Anyway to still make it work?
Can you maybe send a link to what the pin out of your cluster looks like?
Maybe this might help:

Hey. Can you tell me the name of the libraly you used.
Hi, there are a bunch of libraries used. In the video description I’ve posted a google drive link to the entire library I’ve used. You copy the entire library folder and place it in your documents folder. Or if you have an existing library folder you can copy the contents of the files inside the library and paste it in yours.

please can you help me ,, i need conect bmw e46 cluster on bench to inpa and i have problem with conection please it possibel for you wrote simple cable whire diagram to me how it is function conection ? thx
Hi, I assume you are referring to the k-bus circuit. If you are not familiar with circuits I would advise you to take someone’s help or buy this pcb made by one of our discord group members: www.e39simrig.lol/k-bus-pcb-ordering
@@randomscience4k yeas K-bus
bro can i use other dashboard cluster??
Yes, you can. But for can bus based clusters you need to change the can bus ID frames in the Arduino code for your corresponding type of cluster.
@@randomscience4k ok bro
Is there a 12v supply on the arduino? I want to do an audi a4 cluster that i got for free but it needs 12v 1amp even to light up
Hi,
I don’t fully understand which cluster you intend to use since this video is about an E46. But anyway the arduino has only a 5V out put and that too with very limited current range. I would suggest you can get a 12V 2Amp adapter or a small 12V PSU too. They aren’t that expensive. Or the cheapest way is to look around for a computer ATX PSU from an old computer.
i am a noob in wiring, can you tell me the most simple way to make a e46 cluster to work? i only need rpm and speed gauge to work
I think you can definitely manage the speedometer. Well all it required is a simple npn transistor and 1000ohm resistor. But you can also connect a pin from arduino 46 straight to pin 19 on black connector on cluster. It kinda works. The rpm works on can bus. Try connecting pins 9&10 for can high and low to can bus shield can high and low. Also connect one of the arduino’s GND pin to power supply’s ground. That might work I guess for the rpm.
Which pin from relay goes to cluster? like which one goes to arduino and which one goes to cluster?
Only my relay channel set: the ones labeled IN1, IN2…etc is the data input from arduino to enable/disable the relay. Vcc& GND are +5V DC and ground(-) of your 5V supply.
The ones labeled as K1, K2…etc are for the relay outputs. With 3 terminals: Normally Open (NO), Common (COM) and Normally Closed (NC). Hope this clarifies your question.
can i have a link to the site where i can buy the things i need to do it
Check the original article for a parts list
All the parts list can be found here:
neuros-projekte.de/simulator/bmw-e46-arduino-simhub/
Instead of the PN2222A you can get any NPN transistor you like. I used a BC547. Oh and make sure the cluster is a petrol variant not diesel.
hey i am wondering when you dop the e39 low version cluster with arduino uno or do you have some wiring diagram and arduino sketch for me
The pinout is same as an E38 cluster I believe.
www.bimmerforums.com/forum/showthread.php?2211892-2000-740i-Cluster-Help
As you can see from below webpage that for the E46 the pinouts are a bit different:
www.bmwgm5.com/E46_IKE_Connections.htm
I’m not sure if the E46 code would work for the E39. You can give it a try. But I’ve a feeling the can bus codes might be a little different. If you can find the can bus codes for the e39, you can compare it in the arduino code for the e46 if it’s the same. If not you can change it and see if it works.
@@randomscience4k e39 low version have 26 pin on both connectors i know can high and low and the speed sensor pin but that code have made to arduino mega i have arduino uno so what i need to change so its compatible to arduino uno
@@jokkemc-rw8jy I think I did try to run it on a Uno. It's been a while so I can't remember if it worked. But basically you just need to change the platform.ini file details for an Arduino mega to a Uno. Once saves you can flash the code again to a Uno and it should work.
Hi i have some issues, i wired the relay, first i tried for park brake. I wired to good pin in cluster. Relay does the click, but nothing happens on cluster
For the parking brake lights to turn off I think you need to connect it to power supply/battery negative terminal. If you were to connect this to relay terminal, connect the battery negative terminal to relay "COM" center screw terminal. Now connect the parking light pin 23 on the black connector to the "Normally Open-NO" terminal on the relay. Now when the relay is energized your light should also turn off.
Try first connecting the pin 23 directly to negative without a relay to see if it turns off. If this works then it's just that you might be connecting it wrong on the relay.
@@randomscience4k i also tried to wire a GND to pin 23. it doesent instantly turns off, i have to replug the cluster to power
@@Albertt.c I'm surprised it did not work. Even the connection for the parking brake as per manual says GND. What did you mean by re-plug the cluster?
www.bmwgm5.com/Images/E46_IKE/E46_FSB.gif
Anyway what happens if you connect the pin 23 to +12V? From which model bmw did you pull of the cluster. If you can add a picture on imgur the label on top of the cluster it may help.
@@randomscience4k i mean to replug to power
@@Albertt.c okay, I see. Mine is a 330i E46 cluster.
Can it be connected to e34 cluster? I have now e36 cluster it works perfect with simhub, but I like more e34 cluster and eant to make dashboard of e34 integrated with cluster
The E34 is same like the E36, older non-CAN bus type model. I think all you need is the +12V, Ground, Speedo, RPM , Fuel & temp gauge pins. I don't know which model your cluster was removed from. You can find the manuals for older bimmers up to E36 on below website:
wedophones.com/Manuals/BMW/
@@randomscience4k But its same!? Thank u very much bro im buying now e34 cluster and going to fit with e34 dashboard 😊 how can I find out if its older type? I know there is with black and blue back cover
@@randomscience4k Dude Can u please help me I bought now e34 speedo but dont know how to make it work.. can find tacho diagram for it.. I have connected to the same pins where it was on e36 cluster but nothing work ony EMS bulb, back cover is white its from 525 12v (m20b25(
Will the E46 code work with an E36 cluster?
Sorry, the E36 code is little different and much more simpler. The E46 is semi CAN based
Does the indicator only needs power or a signal to the arduino?
Indicator is powered via 12V supply/battery. The arduino controls the kbus and can signals. Arduino is powered directly from USB
@@randomscience4k There ist a Video by Amstudio. He has a wire Plan which is a bit easier with only one arduino. But He hasn't wired the right and left indicator. Do I need a new Script for the indicators.
Amstudios Video is called how to wire bmw Cluster...
@@Agent_Flix The cluster used by amstudio is a non CAN type cluster. So yes all the lights are very analog type and needs manual trigger to light up. I believe he may have left it out as trying to use the native dash lamps will need a lot of wiring. Or just directly use LED lights from arduino and pop it into the cluster lamp sockets. In the latter case no need for relays.
To be honest CAN based cluster projects are way better to activate lamps via software and require very very little wiring.
@@Agent_Flix Yep that video is the most basic one for anyone who wants to use a cluster. Yes, you will need to add a bit of code and ncalc values to get the lamps running. I did code that part in my very last E36 cluster video. But lately people have been saying that with new simhub they are facing issues.
The e46 is kind of semi CAN based.
What is the pin out for rpm signal?
There is no separate rpm pins. It is driven by the can bus.
www.bmwgm5.com/E46_IKE_Connections.htm
Hi, the entire cluster works without k bus?
No, there is k-bus circuit. You can see in video the circuit I made on the perf board.
I did the same but the RPM has a delay, how do I solve it
as in delay do you mean like only when you pause the game the RPM needle moves? If this is the case I had mentioned that opening a dashboard and leaving it in background on simhub helps. If this isn't working then maybe something in simhub has changed since I posted. I haven't used simhub in a while.
Good video
Thank you! Glad you enjoyed it
how do i make the fuel gauge to work?
Hi, the actual fuel gauge if you look at the E46 cluster wiring diagram on website in the description it uses a variable resistor paired with a float system to make it work.
On NeuroProjekt website link in description you can see he has modded the original stepper motor to an arduino servo motor to make it work.
