Volvo V/S90 front seats retrofit/standalone.

[IMAY2023]

Look at his plug, his seat does not have any CAN wires going to it? That's plug block 506. How can he provide it a wake up command?

First of all oleelstad wrote below in his first post. 

I recently bought a few front seats from a Volvo S90 2018 model thinking I would put these in my patrol. Having worked with seats from earlier cars etc I thought this would be straight forward. However that is not the case.

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.
