Those 2 plugs should be from each bottom and back heater pad. They both plug into the seat heater module. A 3rd wire plugs into the module to power up and control the seat temp.

Well… that may explain why my seat heaters aren’t working I’ll have to see where the third wire would come from…. Appreciate it.

So I have the two grey ones… but I don’t see a green one… any input on where that may come from? Appreciate it!

Now I’m finding a grey plug coming front the seat back tucked under the flap, but nothing from the seat bottom. Thinking these seats don’t have heaters. So. Sad. Now I need to find a new set!

Just to follow up with what I experienced, should anybody be in the same situation.... Volvogod was exactly correct. The green plug is connected to the seat bottom heater, if they are installed on those seats. The seat back heater, plugs into a plug that's wired into the seatback foam, which goes to the control unit where the two grey plugs above plug into.

I bought two good used seat heater control boxes and new OEM heaters. Re-programmed my ccm module through VIDA and everything works a treat! I plugged everything in before disassembling the seat and no issues. I finally have ZERO error codes in VIDA. Not bad for almost a 200k mile R.

A few pics of my progress. I realized after the fact (and fixed it) that the back heater pad needs to be pressed down into the voids to allow the seat leather to be held down close to the foam. That was fixed.
