You are going to use your wiring harness from your D16 for your B18? Is that how Im understanding it?

u might need to wire the IAC which is a 4 wire on your harness and a 3 wire for the b18. other than that i think your set to go. i did the same as you, i used my y7 harness for my b18

you're doing an ls swap. then it might be a 2 wire. u might wanna look it up but u will need the connector.just search for ecu pinouts
