The S2 does not have an ignitor like the S1. Instead each coil has its own ignitor. You can eliminate the ignitor plugs on the S1 harness and splice wires together across where the ignitor would normally be in the harness. Just make sure you get the right wires to the right coils or the firing order will be incorrect.

You'll have to look at the RB25 wiring diagram for that info.
