Ignition coil from x20xev with 4 pins has signals on 1 & 2 pins and +12v at ignition on 3 & 4 pin. Newer x20xev ( simtec 56.5) has 3 wire connector and 3 pin ignition coil.

I've just look at X20XEV schematic and it seems that 3 and 4 are connected to +12V.
Probably both terminals are internally connected, so that is the reason it works with 4 terminal unconnected.

thats correct vauxhall only used pin 3 ( on the x20xev ) and didnt bother with pin 4 and we have been running them for years that way with out and troubles even with big boost even autodata doesnt list pin 4
