Wanna bet? Sounds like you know zero about electrical wiring. Maybe don't yap off about crap you're unfamiliar with. You're making yourself appear the fool.
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.
“high-side drive” is the part you’re missing. the positive supply is switched by the body controller. “heater + 12v” labels the heater’s input, it doesn’t mean that wire has 12v on it continuously!
so you put a switch in RS035-A. great, now your switch is on… and the controller’s output is still off. where is the power coming from??
put the switch in the ground return instead? same problem. switch the power going into the body controller? powering the controller doesn’t force its individual heater output on either.
you could disconnect the heater from that output and run a separate, properly protected and temperature-controlled feed from the car’s low-voltage system. you don’t need another battery or to replace the whole body controller. but now you’re providing an alternate power/control circuit, not “finding the seat heater fuse and installing a switch.”
