Seat ventilation switch installed!
Quite easy to install other than pulling the seat out...their Youtube video made it simple.
Note a Recaro seat weighed in at 56.4 pounds (complete with rails, etc).
Took a bit to fiddle with the adjustment, but at full blast - I can feel the air! Should be a nice addition on track - I usually come out soaked during a visit on the track.
Speaking of which, weather is good and I'm cleared to visit Nurburg tomorrow. Looking forward to the new thrust...
