Hey all! I am currently in the process of swapping my EJ2 from a D15B7 to a B16A2. I know that this topic is covered MANY times, but I have a specific question. I would like to know to which extent I need to change my wiring harness? I have removed the three plugs from the ECU and removed the whole wiring harness from the engine bay, but only from the three connectors coming from the passenger firewall to the three connectors from the driver's side firewall. What I want to know is do I need to remove the part of the wiring loom going from the ECU to the firewall? If I'm not mistaken I believe that I can leave this part in because all the connectors are the same from the B series harness? Correct me if I'm wrong.
