I need help converting my DX to Mpfi for my B18a1 engine

I have a 89 CRX dx im swapping in a b18a1 LS motor. I already have everything to do swap, i just want to do electrical wiring first.
Well....I have a Mpfi harness from a 89 CRX HF and injector resistor box and im also going to use a 91 PR4 OBD-0 LS ECU.

What i need to know is how to convert my dx with a B18a1 motor to MPFI with the parts i listed above. Can someone tell me exactly what i need to do?

How come the plug on the DX chassis where the injector resistor box goes has 11 wires and the plug thats supposed to go on that plug on the wiring harness only has 8 wires? HELP
