i have an 89 standard civic 4 speed. and i'm gonna drop my b18a1 in. i know i'll need the integra front knuckles, mounts, and everything else included to do the swap, but the thing i cant find out for certain is what harness to go with. i've heard that you can just swap my dpfi to a mpfi, then everything plugs up with ease and its done. is that true? i've also heard that i need to convert it to mpfi and then to the b18 harness.let me know asap. thanks
