It is all there?
The block below is the overload (O/L)
What do you want to change?
Although it looks as though the contactor is not fully populated as regards AUX contacts 23-24 & 41-42 is not fitted ?
13-14 & 31-32 are not being used.
Looks like Pre-DIN style!

Sounds like you need to intercept the coil terminals, (not shown) but appears they could be the white and orange on the R.H. side of the contactor.
