Hi Kelly, there are a few models of this pcb and it looks as if you have the wrong one for the model.You should have a W0000059 or on the packet after it will say w0000024.These have the live and neutral soldered in and the new ones are the block as you say.
To have the correct one would be best but I am sure that you can put the live and neutral in the block as it indicates.I do not think that the wiring is different or that there are a different number of wires.All the best.
