Have you tried a three-ground airbag with three-ground wiring with blue/white wire through pin T12/8? I imagine that it is the only possibility you have to work your horn with those NEW buttons (J453 'lin'), although it is possible that if 'your' J527 detects MFSW it will try to make the horn work ...

So it looks like I _should_ have blue/white in T5/4 instead of T12/8 like I had from the beginning? Since you said that T12/8 is not assigned in MFSW and I have one. But again, in J527 T12/8 is used for horn...I'm lost. Strange. People seem to have successfully retrofit mk7 to mk5 steering wheel wit...

I had BH module for SW but it was also for simple coding. Had to replace it with CD because of LIN2.0 support (I had golf V MFSW originally)

I don't have advanced coding for MFSW

Two grounds (brown/blue-white) are for the horn (switched ground) and the other for the multifunction steering wheel control unit J453. In some airbag wiring, the 'direct' grounds (not the switched one) are spliced into the wiring itself. I guess that's why some airbags don't have that extra ground...

I can't use it sadly... Yellow plug doesn't match to my clock spring socket. I'm already using another airbag also without working horn, but it has another construction flaw hence I bought another one... so... I would like to use wiring loom from my current airbag to that new airbag...but there's a ...

it looks like T12/8 is occupied by the white cable, from T5/5 (cruise control signal). you can remove T12/8 an run a new wire to the horn plate. or, cheat a little bit and remove T5/5 and connect it to to T5/4. I'd do the first, do it properly. But for testing, you can connect T5/5 with T5/4. That ...

Insert the wire with the MQS terminal into T12/8. Similar to this: https://i.imgur.com/xutGbot.jpg https://i....

And that's what I'm kindly asking here for. My buttons are already working, but not horn. What and how to wire? Which one and where?

Hello. I know this is Polo forum, but here's no offtopic category to write about things for other VWs so I'm writing here. I would write a private message to @ciclo but as new member I can't. I have a Scirocco and I just bought golf MK7 style steering wheel. I couldn't find MK7 style airbag for scir...
