I would bet a very large sum they are Katzkin, simply by looking at the pocket behind the drivers seat. I have Katzki in my truck and it looks the same.

As far as the heating elements with a Katzkin kit you have three options from my searching: go without, install factory elements with Katzkin kit, or use an aftermarket kit which may or may not work with factory controls. I chose to utilize the existing factory which are stitched into the oem seats so they have to be cut out--huge pain for my instatller. They do not get as hot as the oem setup, but they do the job.
