    so I take it you own an 88-91 civic/crx DX or STD vehicle eh ?

    "can i just front half the harness? that seems like the easiest way to do it if it will work.(take the harness from behind the ECU forward and replace it with the one from the b18.)"

    Wishful thinking there....although I wish it to be that easy too but its not!

    You cannot simply add on an MPFi engine harness on go, its more than just that. You need to add wiring for 2 more injectors and a few other things. I really do hate the DPFi->MPFi conversion with a passion.
    but here's a few sites that can help out with your situation:
