Have the opportunity to swap my rear seats for the split folding seats. The rear seat is also heated and my car wasn't spec'd with rear heated seats. Will this be as easy as finding a tucked connector for the heating elements and then replacing the rear center console with a version with the rear seat heater buttons and plugging those in to a tucked connector? Or will those connectors not even be present??

No. You will need wiring harness(es), switches and probably more miscellaneous stuff. Add coding after that.

To the OP, there are two versions of the rear heated seat "buttons"....

1. Embedded in the 4-zone Rear Control Unit
2. Two Buttons under the rear center vent (pictured below)

#2 would be the easiest to MOD for your car, but still would require you to run wires:
- For the Buttons:
- - Power from JBE, Fuse F31, to rear of center console to both switches
- - K-LIN from JBE to rear of center console to both switches

- For the Heat Modules (under the seat cushion)
- - Power from rear fuse box, F188, to rear driver's side module
- - Power from rear fuse box, F187, to rear passenger's side module
- - K-LIN from buttons to both modules

You'd need to find a rear vent trim that has the two holes for the heat switches, and then switches.

You could do this at a later time after you've installed your split rear seat...

Thanks for this info, it is extremely helpful. I think I will still go through with retrofitting the folding seats, but probably won't bother with getting the heated seats functional. At least not at this time. If COVID continues to drag on into the summer, maybe I'll decide to take on that project, but I have enough going on right now.

Hello. I have 4-zone Rear Control Unit. I need wiring diagram. Please help me. Thanks

furkan24 mind sharing your F10 manufacturing date? Wiring may depend on it.

My car 2010. . Power and ground wire okay. Rear fuse 187 & 188 power . But I don't know where the 2 yellow and 3 brown cables will be connected.

Hard to tell what that wire loom is coming from....

Here is the 1st schematic....and if you need more info on this module, let me know. Rear Seat Heater Module will be provided in the next post.
