I want to upgrade my steering wheel to a heated steering wheel. I would like to know if it possible for a plug and play, or would there have to be other wiring done to make it happen?
you need the steering wheel with heat option and a clock spring that matches it, then you just need to run a power wire to the clockspring from a accessory power source.
the clock spring sends the power to the steering wheel you just need to connect the power to the clock spring connector.
you want accessory power so that you don't ever even accidentally leave the steering heat button on and drain the battery.
you can find the bcm power pin outs with the gm upfitter guide which is free online
