Anyone added an aftermarket seat heat kit to leatherette seats?

I think they might be glued, and it may be a huge hassle.

 

Haven't done it in the MINI, but have to a Miata. They don't 'glue' them, but they do have a sticky side - otherwise they'd slide all over the place! The toughest part is figuring out a place for the switches! The OEM covers have special pockets for the heaters.

 

where do you get these?

 

I was thinking of trying these out
