It would cost you a bundle due to the air bag, but the wiring should be there to connect the heater on a such-equipped steering wheel. I assume this because I was able to swap the rear view mirror in my Taco for one with a compass and the necessary wiring was already there.
Thank you for this. I’m told of the wiring coupling is there it can be done. I’ve called two Toyota dealerships and talk to the parts guy. Both didn’t know what I was talking about and said it’s impossible, But they couldn’t tell me why.
I think it can be done. I think the electrical connections are there.
