Sorry to ask about this but I’ve searched high and low for this diagram and cannot find it. I have a 96 wagon lx 5 speed that previous owner half ass swapped a H22A in it. Ecu wasn’t replaced. I bought a P13 ECU and working on the wiring. Problem is, the factory wiring isn’t matching any diagram I can find. Example, A3 and A4 are black wires in mine. It is a factory OBD1, verified this over and over. Anyone out there run into this?
