I've got an SX, which is the Canadian equivalent of the SX-P (with a couple features missing). I'll see if I can take a couple pictures of the base of the seat for you, but I don't think they are easily accessible to be removed.I know what the dealership would say. Heat and ventilation require only an electric harness, as I doubt ventilation is actually due to ventilation duct/piping but rather a fan installed into the seat. There is nothing complicated about twisting a harness (or disconnecting and reconnecting an electrical harness connection). My question is whether the installation mechanism on the sliding track is asymmetric and prevents the chairs from being rotated. Not whether the dealer says it can or can’t be done. There are plenty of things that can be done despite what the dealer says. This would be more obvious if we could get our hands on a dealership digital service guide/repair manual. Once I take delivery, I will probably try to take it apart at the base enough to see whether this can be done if no one else replies first.
