I have taken this pic from the NTSB Powerpoint presentation which is the highest resolution image I can find of the monitoring connections to the individual cells.
No obvious temperature sensor connections although the chewing gum/cotton wool over the shunt between the middle two cells on the LHS of the array looks as though it could be hiding something although it is probably just a mirror of the connection on the shunt of the RHS.
