Just a node here.
Getting to CCM or the CCM connector is very hard. In most cases, dashboard needs to come out. So, the LIN for heated and ventilated seats from the seat controller to the CCM can be tabbed to
1) 4/204 SEAT HEATING MODULE RIGHT SHMR > 4/229 HUMIDITY SENSOR HUS (A2 green)
2) 4/203 SEAT HEATING MODULE LEFT SHML > 4/222 CENTER CONSOLE SWITCH MODULE CCSM (A5 white)
If rear heated seats are added too,
LIN of the rear seats are on the same LIN bus as the fronts. Left to Left and right to right. If the car already equipped with 4 zone AC, it is possible to control retrofit rear seat heat / vent from the center display. (rear climate page). If the car does not have 4 zone climate, a switch should be added.
Ventilated and heated seat modules have the same inputs, (LIN, Ground and Pos) the only difference is the output for the seat vents.
I retrofitted from heated to (Heated / Ventilated and Massage) seats. I only needed to add the power for the seat comfort module. 5AMP to fuse box shared by both front seats.
