Heating retrofit in Monte Carlo seats

Hi!

I was looking for a seat replacement for my second hand daily that purchased last year.

On my web browsing journey I found a full Monte Carlo interior in great condition and I didn’t doubt that it was a great opportunity. They just need a good wash and ready to rock.

The only bad side is that I would like to keep the heating feature, very used where I leave.

So here I am, looking for the right OEM article numbers.

This is what I found in LLL parts as original article numbers:

Bottom part

5J0963555A

5J0963555C

Backrest part:

5J0963557A

5J0963557C

Both are numbers for sports seats.

Which are the right ones?

Do I need anything else apart of the heating elements? My head says no, but better to ask.

Anything to suggest?

Thanks in advance!
