ok i did a b18b into my 00 ex and all the wiring went smooth ...we had to switch plugs from the jdm harness with a plug near the tranny and the dizzy wire we put the d-series plug on the jdm dizzy and the ex harness oblivously plug in but we have a blue wire just chillen with nowhere to go.....my problem is that im getting codes 71-74 random cylinder misfire but my car runs fine.......could it be the ecu is bad( im borrowing my friends because mine comes in the 11th), or the knock sensor is just throwing gay *** code because its fucked,or the d-series plug on the b-series dizzy(but idk why that would be a problem b/c the wires should be the same)......IDK HELP i have the CEL light on in my car

What obd is ur b18? That's strange if it's running fine but giving u the codes, my guess would be it has to do with the blue wire going to ur dizzy, the main blue wire I know of goes to the ignition coil i think so if that was unhooked it wouldn't start, so it must be a different blue wire, u can take apart ur dizzy, and trace the blue wire that's not hooked up, and tell me where it goes (ignitor, ign. coil, sensors, etc..) and I'll help u find where it goes to ur ecu.
