Carlen - Sorry I guess my morning coffee hadn't had it's full effect. You are right. The ortho seats are pneumatic and only require the controls between the seat and console. I was thinking of the retro fit for the heated seats which require the switches.

BTW, I've read one post where they stated that the 'pockets' for the air bladders are present and you only need to insert the bladders. Hopefully that's true for yours.
