I have a 96 civic EX with a d16y8 in it (of course) that decided to "blow up" on me. So I ordered a B16A SiRII and I am needing to know what what the hell to do about my wiring harness mess. Should I go buy an OBD I wiring harness and ECU?? Is there any way to use my existing wiring harness?? Everything came with the motor I ordered as far as alternator, ECU, tranny ect. I swapped the fuel injectors from my d motor to my b motor to work with my current wiring harness. The ECU the company sent me is also an OBD II ECU so I have no need for a conversion harness at this point if I can use my existing d series harness that is in my car now. I also have a new dizzy on the way to match my OBD II wiring harness. So will someone please tell me where to start or what I need for this mess.
