Your stock si harness is mostly plug and play. You will need a dizzy plug from a dx harness for the dizzy and the 2 wires left over from that will need to go to the cam sensor on the exhaust cam. Your si's PM6 ecu will be able to run the engine ok. A PG7 out of an integra or a JDM PM7 would be good as well.
