L322 comfort seat install

I have a set of MY09 cooled/heated seats I am going to put in Sprinter van. in a nutshell I would like to get the cooling function working. I have all the motion going but plan to skip the memory. I have looked for two days now for a wiring diagram on the cooling feature in this seat but have not been successful. I found an older post where a contributor states he has one but can not PM him until I get three posts. so I thought I would use one of the the post to throw up my issues directly for all to chime in on. I dont think the body control module is needed without the memory feature (plus I dont need mirror or column control). One thing I have not pieced together is where the temp for the seat is controlled? is it in a separate ECU? or does the heat/cool switch come with the smarts to take feedback from the thermistor? I doubt it but one can hope. any and all advice/experience with the cooled seats is welcome!

I was told that the heating/cooling element switched based on the direction of the current applied. I've never lookied inside to verify that. If true, it shouldn't be too hard unless there's a computer overseeing the whole thing.

There is an ECU controlling the temp/ the TEC or Peltier is a current directional conductor so changing the flow creates heat or cooling. what i cant find out is where the control module lives. the wiring under the seat does not match the control unit. is there a wiring loom that that goes from the seats to the control unit. I plan on visiting a dealer tomorrow to crawl around a few RR with comfort seats.
