to the forum. The yellow plugs are the SRS wires and only play with these when the battery is disconnected! Pull both seat plugs then reconnect and put the battery on, then try resetting, if they wont reset then have the codes read properly so you know where the fault is so that you can investigate further. You may have a snapped wire, dislodged pin or even worse a faulty clock spring unit.
I am sure it's an easy fix related to the seats though
