I'm also interested in how the massage is connected, via a canal or a line. But first and foremost, heating and ventilation.

The seat ventilation and heating has nothing to do with the seat controller unit.
It has its own LIN SLAVE module with a seperate power input about 20 AMPs. It's LIN slave module controlled by the CCM (climate control LIN MASTER).
Hacking a LIN is not that simple because each LIN MASTER and SLAVE responds to specific messages coming from a specific message ID. So, you need to capture the relevant LIN messages between a CCM and Seat Heating module then send those messages to yours.

That's what I was planning to do. I wanted to know if anyone could record the data coming from this LINK channel for later playback on my end.

Regarding massage, is it possible to save massage commands from the LINK channel? As well as commands for saving seat positions and commands for playing memory commands.
