Mk4 VW Multifunction Steering Wheel Retrofit
Вставка
- Опубліковано 4 жов 2023
- I wire up a standard Mk4 with a multi-function steering wheel for cruise and radio controls. Not so straight-forward! Especially on 2002 and later Mk4s using Kufatec's wiring kit.

Love the show.
Very nice i have mk7 golf wheel in my mk4.. horn and airbag works .. any tuturial to make the buttons just light up
Hi! I love your work , greetings from Argentina.
I would love to add MFS to my Vw Golf 2004 (Mk4) 1.9 TDI , it's an AGR 90cv Model with EDC15VM+.
I got the same steering wheel in the video from a 2010 Volkswagen Sharan, (the same one in the video). Any advice to install it?
I i want to change my steering wheel from classic to the button's one (just for the light) I need to make any changes to the airbag plug ?
I go to the u-pull it style junkyard and get the whole steering wheel, air bag and air bag harness that it came with originally.
Good video! But how about the pre 2002 cars? Mine is a 2000 with CC and non ASR/ESP and doesn’t have canbus could this be possible for mine?
Not with the radio I used, but with the factory single DIN they used from 2000 through some early 2002 models, yes.
It's wired differently. There is a wire included in the Kufatec kit that I actually removed for the car I was installing it on, it will run from that relay to the back of the radio. That's how the signal is getting to the radio.
The Kufatec kit I used is honestly wired better for the pre 2002 cars because it's already setup for them. I was removing wires/signals that the later cars don't need, and then had to add CAN bus wires because that's where the later cars get those signals from, and how it outputs to the radio.
You will also want to find the "452" module to go with it instead of the "451" that I used.
Any aftermarket radios might not accept the signal from that LIN bus wire. Unsure on if there is any converter for those signals for that setup specifically.
But, you would at least have working cruise control from the steering wheel controls when done right.
I like the Chinese RCN210 VW radios. It is a factory VW radio and with the right CAN bus adapter for the 2002 and up cars, it does indeed respond to the MFSW steering wheel controls. Modernizes the car just enough with basic bluetooth functionality.
Dang it! Thanks alot for responding I also have this RCN210 installed on my Golf and I love it but I was afraid for that response 😢 I wish it was possible for my car I guess Im gonna sell the Steering wheel and relay that I have
It was very good, congratulations!!!
I have a Golf MK4 I want to do it on mine too, which VW website are you using to get this wire connection map for the relays?
I download it all from ERWIN.VW.com
$35 USD for 24 hours worth of access to download whatever repair info you need for cars from the mid 1990s or newer
@@dzelpwr Thanks a lot for the help .
My Golf mk4 2004 needs to turn on the cruise control, this will help a lot, thank you.
@@CarlosSousa-gv6sg having VCDS or similar VW scan tool will also help greatly.
First thing I'd do with trying to figure out a cruise control issue is to look at measured value block 006 on a diesel, or 066 on a gas engine from that era, make sure all the switches are being recognized correctly.
See what the ECU sees. It very quickly helps you narrow down which area to focus on.
@@dzelpwr Thank you very much for the tips.
Great vid man . do you know where I can find the wiring diagram btw?
Thanks in advance.
you can try this
T18c Pin - color/stripe - function
1 - orange/brown - CAN Low (in 2002+ cars that use 451 relay and CAN)
2 - - no connection
3 - orange/brown - CAN High (in 2002+ cars that use 451 relay and CAN)
4 - black/white - Cruise related, clip on to wire from T10s/4 or T10s/7 from signal stalk, or tap-in to T10e/3 (connector in water-tight box)
5 - lavender - REM wire for remote control of radio, to T20/11 "green" connector behind radio head unit, not needed when using 451 and CAN
6 - green/purple - K-wire (diagnostic wire) T16/7 in instrument panel wiring harness, (OBDII port), below inst. panel, left
7 - - no connection
8 - red/yellow - Cruise - tap-in to T10e/2 in water tight box
9 - brown/yellow - connect to horn relay, S1/6 (bottom left on relay panel, marked "53"), cut wire that is already connected there (it currently goes to T5b/3 on steering wheel) leaving a stub of a few inches from S1/6, and crimp T18c/9 to the stub of S1/6
10- brown - Ground, 1 in instrument panel wiring harness (Brown wires above clutch)
11- - no connection
12- black/red - 12V switched, connect to Fuse 5 in fuse panel (7.5 Amps) When connecting, you should splice this T18c/12 wire AND the wire from T5b/3 that you cut from S1/6 above together into the wire from Fuse 5. Therefore 12V switched from Fuse 5 should go to the middle of T5b/3 on cancelling ring AS WELL AS pin 12 on T18c-- T18c/12 does NOT need this w/ CAN (451), BUT T5b/3 STILL DOES!
13- red/green - 12V power, connect to fuse 40 in the fuse-panel but if you don't do that, you should use an in-line fuse
14- red/grey - Cruise - tap-in to T10e/9 in water tight box
15- grey/blue - ILLUM wire - tap in to T3c/3 in instrument panel light dimmer switch... Not needed w/ CAN (451)
16- blue - Cruise - tap-in to T10e/1 in water tight box
17- - no connection
18- yellow - Horn, T5b/1 on cancelling ring (at steering wheel) you will probably have to add this wire, it is on the far right of the yellow T5B/1 connector on the steering column as you are looking at the steering column.
I get my VW repair info from ERWIN.VW.com
I removed the MF steering wheel in my car, then I put in a three-spoke steering wheel, but I have problem with horn it does not work for me, can you explain the schematic from the MF steering wheel to a regular steering wheel. thank you
Yes, you cannot swap between wheel styles without completely rewiring the car.
There are only 5 possible total wires that can pass through the clock spring to the wheel. 2 of them are for the air bag (pin numbers 4 and 5, respectively). On a standard, non-MFSW setup, there will be two other wires that are just for the horn. One is ground input (pin 2), the second is the output from pressing the air bag, closing contact from the ground input to the second wire which is now a ground output going to the horn relay under the dash.
Pin 2 at the clock spring is ground input no matter which wiring variant you have. Pin 3 is ground OUTPUT if you have a standard steering wheel. On an MFSW car, it's actually a POWER input at pin 3 to power the button module in the wheel. So, I would not be at all surprised that if you attempted the horn on a non-MFSW steering wheel in your car wired for MFSW that you actually popped fuse S5 on the side of the dash because you would have created a dead short to ground for fuse S5. S5 is required for a few little things, like the control modules for the heated seats and for the data-link connector for the scan tool to connect to. So, if you find a scan tool has a hard time talking to your car or does not power up when plugged into your OBD port, that might be why.
The last pin on an MFSW car is pin 1. There is nothing at pin 1 on a non-MFSW car. That one wire is carrying signal output from the buttons and horn in the steering wheel, sending it to the MFSW module that lives on the relay panel for that module to decode and either actuate 12V signal outputs on individual wires to the ECU for cruise control or to send a ground trigger signal to the horn relay, or to convert the channel or volume up/down signals to data packets on the convenience system CAN bus on 2002 and newer cars, or to send them on an individual LIN Bus wire direct to the back of the radio on earlier cars.
In order to make a non-MFSW wheel work on a car wired for MFSW, you would have to remove the power wire from pin #3 at the clockspring, run a new wire from pin 3 direct to the ground control side of the horn relay.
many thanks for this info, as I have the same issue on my car
please, can you share the location of the horn relay and the pin number should I connect to the pin#3 at the clockspring
Also, should i cut the wire from horn relay to the 451 module @ pin#9 ?
many thanks for your support 🙏
@@dzelpwr
Did you get it working? I got the same problem..
@@dzelpwrHello, thanks for the great video! Can you tel me wich one pin 3 is or how I can find it thanks.
Здравствуйте хорошо было бы если на русском языке.
