Upgrade cruise control on the A6

Moin. I’m in the process of upgrading my A6. I bought a butcher for that. I want the tempomat seat heater and el window back. 2. And 3. I don’t think I’m going to be a big problem. But what do I need for the tempomat and makes a difference that the butcher is an automatic and the tempomat in a switch? Thank you
