can I add the stock seat warmer to the aftermarket seat?

Hi,

I'm going to say it will be based on the seats you get. There are two heated mats in the seat. One is on the back section and the other is where you sit. As long as you can remove the cover to install them, it should work. The only concern I would have is, fit and finish. Often the type of seats you are referring to are molded differently which may prevent the mats from fitting.

I attached some general replacement directions below. Take a look and let me know your thoughts.

Take care,

Joe
