See post number 3 of
this link. I just got my letter yesterday as well. Checking the connectors was not a big deal - took about 10 minutes with a 10 mm socket. I went ahead and checked connectors on both the right and left sides (two connectors on right side, one connector on left side) - they all looked perfect. No signs of burning/melting/heating.
Hardest part was threading the seat belt buckles when putting the bench seat back.
Regards.
