So I will be picking these ST3 seats up next week and I have been reading on some threads about hooking up the seat heaters and people say "looking in to it" or "they will install them later", but I am trying to get the seat heaters hooked up with the factory switch. From what ive read is if your FiST doesn't have seat heaters (like mine) could you just order that single seat heater switch to go along side the "ESC OFF" button and the opposing Ambient lighting button and run your own wires off the back with a relay? Any help I would appreciate it!
