I can't read the chip numbers ;-(( One will be the interface
IC (HD44780 or similar) the other will be the supplemental
driver

You can usually easily find the IC pin that a terminal goes
to with an ohm meter. If you have a data sheet for the IC,
bingo. Don't count on the header being the same as another
model - been caught like that. The chances are that it will
be, but assume nothing. Absolutely essential you identify
the 0V and supply pins, LCDs hate it backwards
