That's a pretty generic Chinese BOB, however I'm not entirely sure of the pinouts.
I do however know the original Denford wire numbers, but they don't seem to match the hand written marks on the terminals -
57 - Home 2 (Z)
58 (assuming the 5 has fallen off) - EStop monitor signal
66
67
68 - Estop relay coil
78 - SGR (Spindle Go Relay)
66 & 67 would normally be the wiring numbers for part of the E-Stop loop (depending on the spec, the EStop loop can go through EStop button(s), limit switches, Guard interlock, and spindle motor overheat, with the wire number incrementing between each switch/sensor capable of breaking the loop).
This is the BOB, which will give you the pin mappings

I'm going to open the box up and see if I can trace some of those wires/numbers
From the BOB pinouts and looking at the wiring I have set the following:
66 - X Home
67 - Y Home
68 - Z Home ( however this one doesn't show in the diagnostics panel as being made at either end of the Z axis travel)
57 - E Stop
58 - Ground
