Hey everyone, title is a bit weird but wasn’t sure how to title it.

I just did a saddle brown color interior swap on my e90.
The seats I swapped in are heated and the donor car was set up for that so the seats work in that car.
My car did not come with heated seats and now the heated seats I swapped into it are not working.
Well the driver side is working, but the passenger side is not working.
The seat belt dash light also turned on.

Does anyone have an idea what might be happening?
Maybe seat connector harness has to be re-pinned?

The saddle brown wasn’t all that great as I anticipated, so I will switch back over to gray if I can’t get this figured out.
Thanks in advance.
