I have a 2018 Land Cruiser that I am looking to improve some of the standard functionality on. I would love for the steering wheel heater to automatically come on when the driver seat heater automatically comes on high. Does anyone have any thoughts about how to explore this potential modification? I assume if I can trace down the trigger wire that turns the seat heaters on I can do a simple circuit to the steering wheel heater to turn it on. Has anyone played around with this idea yet?
