Fitting spark igniter to Smev OF311FGT oven.

[68c]

Need advice wiring replacement spark igniter to Smev OF311FGT oven.
Took the side cover, seems spark ignition does not work as igniter unit removed by previous owner. Wiring and switch are present, so ordered replacement igniter. Came labeled UBZ6(12). Unfortunately no wiring instructions. I have identified the negative and switched 12v positive wires and the two leads to the grill and oven igniter electrodes. It looks like the end two terminals labelled 1 and 2 are for the positive and negative feed but which is which, similarly there are six terminals labeled a to f, I assume I can connect the two electrode wires to any two of these.

I realise this is an old post, but I wonder if you ever got this sorted? Was the ignition unit the right one for the oven? I’m guessing that the “spark out” line needed an “earth line” too? So this unit looks like it would do several igniters? I also expect that there needs to be a thermocouple feed back to tell the igniter that ignition has taken place?
TIA if you can remember this far back - we have the OF311FG oven and the grill igniter is sticking on so I’m looking for info on this model.
