First of all oleelstad wrote below in his first post.

So the wiring you mentioned

is wrong!  It's for XC40 which is very different. The seat controller on those are not CAN BUS units. They are LIN bus slaves of the CCM.  
Besides, if you look closely to the pictures of the seats in the initial post of  oleelstad on the first page of this thread, those seats are manual! There is a handle beneath the seats! 

So, there is no seat controller to wake up! The wires you see in the picture of the connector are for the airbag, seatbelt, seat occupant sensor, the lamp under the seat and ground. I don't even see the power wire "red same gouge as ground " for heated seats.
