jdm d15b swap!!

Hello there!I have a jdm d15b vtec,and i have it ready to into the car,and i relized the wiring harrness that i'm using from my old d15b non vtech does not have the vtech plug's?I'm using that one because the harness on the other one has been cut!!I also i'm going to use a pr3 ecu to run it,will this work on that engine?..And the wiring coming from the car it self will it work?..Is there something that i could buy that will run the vtec only?..Thank's
