Crxdriver1989

So this weekend I put a JDM B16a Obd 0 into my 1989 Crx Dx. Everything is bolted down and sits correctly. The only issue I ran into is the fact that the harness doesn't connect to the round plug closest to the windshield on the driver side. ( can't remember the name of it at the moment.)The Plug in the Crx (DPFI) is smaller than the connector on the B16a harness. The engine was taken out of my old 89 civic Si (MPFI). The harness that I currently have in my Crx is the harness from the B16a and not the stock Dx d16 harness. I would appreciate if anyone could help me out and put me in the right direction to have my car on the road this weekend.

Thanks!
