Im not sure if the ID's are plug and play but one way to find out. Essentially remove the old injector clips, there is a metal clip that needs to be removed then it'll come right off. Then either that plug will fit right onto the new injector or you will need to get some pigtails and solder then onto the old injector wires or purchase some plug and play adapters.

 

Yes, the plugs are different so it would require modifying your harness, or using plug and play adapters.

FIC 1200s and 1650s have the same plug as the factory Evo 8 and 9 so no wiring is required .
