It should be right next to it, a grey connector.

AFAIK it's not a pukka OBD2 plug though, just a three pin connector?

Well it isnt grey then

The service connector is the two pin one, the OBDII will be the other one.

no !
there is no OBD2 connector on Euro preludes, but you can find one on US, Canadian Preludes for example.

The UK spec 5G, or the H22A8 5G at least, uses a OBD2a P5M ECU which has a 3-pin plug, rather than the more common (and widely supported) 16-pin OBD2 plug.
