just out of curiosity, conversion done out of interest or is there really an advantage?
5Q1953549G clock spring supports start-stop engine and drive profiles buttons. It is installed in Cupra Leon and Formentor with those additional buttons in steering wheel. That clock spring has two additional connectors (pin 5 and 6) which are absent on any other clock spring

This is great information gathering, well done!

I notice on your spreadsheet that some information, like what vehicles some stalks are fitted to, are missing. Is there a specific reason for this or just not got around to those ones yet? For example, 5FA919719AM is for Leon KL.

I couldn't be bothered to much to verify and fill every missing information, especially when they are not crucial regarding features. Maybe some day, who knows. That's all :)

A little update with 5Q1 steering control module... Found the bug, that Blue/violet wire from gear selector lever must be pinned to BCM T73A/24, other vise car don't see that it is in Parking, also can't lock car doors in any way... I will update my post about wiring also to avoid problems for other retrofitters.
Now, all things work great as they shold!
