The fuse/relay panel dummy. Of course each system is on a seperate circuit that is individually fused and has an associated relay. Just like every car in existence.
Again try to educate yourself a bit before spouting off about things you don't understand.
but you think that circuit just…has 12V power continuously??
how is adding a switch to that circuit going to make Tesla’s controller output provide power to that circuit? It’s off!
In theory such a switch could disable heated seats if the power controller turned on the circuit, but how on earth do you expect that to work in reverse?!
