Help!!! obd2 B16a into 97 civic with D16y8

[JDM-95-Hatch]

I have a 97 Civic with a d16y8. Well I got the motor out and was changing the harness over to my b16a obd2 motor and noticed that the harness from my car has a box that plugs into the injector harness with 2 vacuum lines that connect to the manifold and the new motor does not have the box or places for the vacuum lines just the wires for the 4 injectors, do i just hook the injector clips up from my old harness and leave the box unplugged with no vacuum lines or do i have to rewire the injector harness that came with the b16? much appreciated if anyone can help me out..
