Same here. Well minus the mods lol. We have a 4month old that takes up our time and I just have the track apps cluster to finish up and try to figure out why my illumination is out on my steering wheel switches, headlamp switch and trunk/hazard switch..

I can confirm what vartech suggested to do worked. Now I got all the buttons working for the upper right hand switches. One down 3 to go. Yes I suck at soldering lol 😂

This is cool. I may follow suit if you are able to get all the buttons to work, including cruise control.

Glad it worked. Let me know what buttons you want to work on next and what responses you are getting. Hopefully it will be this easy for all.

Any progress on this ?

Nothing yet. I only got the media button to work amd bought and airbag for it. Still havent got the message, cruise or bluetooth/sync buttons to work.

I did manage to redial calls with the lower right switches. Thats pretty much it been busy with work and the newborn.

This would be an awesome retrofit if 100% complete! because i seen some sick custom steering wheels from Kratos_Carbon_Wheels on Instagram.

No updates yet. I have been using the steering wheel and its fine. I'm thinking of just changinf out the resistors to see it that would make the switches work. Also been thinking og getting the gt350r wheel in red stitching 😶

Excited to see if you can 100% make it work! lol

BUT I have my OEM 2011 Wheels modified by Kratos and it's AMAZING... It was $950 for a full custom set up to how I wanted it.. Stripe, stitching, leather color, carbon fiber color.. i mean they have ALOT of options and let me tell you. Quality is AMAZING! totally worth it!

Check them out on IG: Kratos_Carbon_Wheels

I am also interested in this. My S197 steering wheel needs to be swapped, I Was thinking of going with the S550, and would love for the controls to work.
Vartech, did you get your push start done?

I finished the OEM nav, 2014 cluster and the select a shift shifter. Doing OEM back up sensors next. Gave up on the push start because kept getting boxes with the wrong stuff and when I contacted the manufacturer they wanted me to pay for shipping to swap out parts. Did not give me a good feeling. So gave up. I am very interested in doing the s550 steering wheel so I am watching this thread.

No updates as of yet. Im thinking i might need to change out the resistors to make it work. Right now I have the audio working air big not connected yet.

I want it
 

IT looks from your posts like it would be worth attempting this, do you agree? I would love to attempt it, however, I'm not very electrically inclined, I could follow your instructions, but without instructions or ideas on how to do it, I don't think id be able to get the cruise working.

To me its worth it. I loved the steering wheel on the s550. If I knew what resisters I can remove and install to make it work. I'm contemplating on getting a s550 steering wheel column housing with switches and clock spring to see if that would work. But dont have the time to fully work on it..

Got one on the way, I'm hoping I will have help, I did order with the column and all switches and harness.

I'll help with whatever I can. I do have diagrams if needed. The one thing is the s550 steering wheel will be thinner then the s197.

Small update:

got the column and it fits!!

Thanks. Unfortunately its not gonna work since the s550 goes from the column to a media communications network module. I'll probably figure out how to axtually make it work. Also the back of the column housing is hitting the cluster when all the way up.

I just ordered resistors for the info/message buttons. Hopefully it works. Then on to the cruise buttons. Its gonna be awhile but Hopefully it works and can share some info.
