Passenger seat bottom cushion replacement?

I bought really cool seat cover replacements, leather seating surface and matching vinyl surround.

Also bought two seat bottom cushions "durafoam" for a better ride (12-year-old truck and Florida heat hurt the stock cushions)

My question. The passenger side has a "seat sensor" which disables/enables passenger side airbag, it also controls the dashboard light and alarm for seatbelts on the passenger side.

I can't get a passenger side seat bottom (haven't found or not in stock) and I'd like to swap parts for the sensor, stock cushion to durafoam aftermarket seat bottom.

Any hints?
