Yes on eBay. They are not cheap anymore ($70ish). I use the OEM switch with the aftermarket rocker. I painted the back of the switch so the dash light didn't shine through the white and into the "on" light.
I swapped my lower panel for one with more switch locations today. The heated seat switches will get hooked up when my new PRP seats get here. I've got another switch for my spot lights coming to fill the top hole. I'll use an aftermarket rocker on the OEM switch there too. The lower areas are for future lockers (front & rear), air compressor, and power inverter.

Looks great! Are the seat heater rockers 1 step or 2 step switches?
