r8 button TTs 8j steering wheel

[armran]

hi all, I would like to mount on my original TTS 8j steering wheel, 2 r8 style buttons; on the left the black button that I want to connect to my sport button e. on the right the red button that I want to connect to the key or to a keyless engine ignition kit;

1) which possibly wireless buttons do you recommend that are compatible with the shape of my steering wheel shown in the picture and therefore have compatible brackets?
2) how should I modify and adapt the wires to connect them to my car I have tried to contact many sellers and no one gives me a positive answer, I have also contacted VagExpress and they do not reply to me in any of its channels

look at the photos I posted, I found pictures of some identical steering wheels equipped with the modification I want to make

could any of you who made this mod help me?

That's a specialist setup & wont be cheap at all, button set itself looks like they've been taken of a newer wheel, very customised & either they've added a wireless controller, bus module or additional wiring through the slip ring to another unit, its not a simple mod.
