ok so heres the deal..i dropped a b18a1 into my 91 hatch and im having a few problems. its a DX so i had to grab some 5 speed hubs off an si. not a problem. but then i heard that ill need to rewire my ecu harness for MPFI. so i downloaded the wiring schematic and i understand it. but my question is...would it be easier to do this with the original d series harness or use the harness from the b18?
