Retrofitting a old Tesla seat into a office/gaming chair

I was able to get a hold of an old Tesla seat.l and was thinking about modifying the seat into an office or gaming chair. I’ve been looking scouting around the web for ways to make the electronics like the heating, cooling, lumbar, and seat rails to work but no one really goes into depth on tools, cables, wiring, etc. Some say it’s some type of relay while others say controller. So I just wanted to see if anyone has done this before has any tips on working the electronics.
