I am doing an obd2 b18b1 engine swap in my 1992 civic and I was wondering what wires need to be added or swapped. I am running an obd1 pr4 ecu also. I see that the ecu doesnt have a knock sensor and neither does he engine so that eliminates that wire. Do i need to run the wires for the evap purge power and the evap purge solenoid. I cant find any reference that tells me exactly what to do. All the resources that i have found are for an obd2 b18c1 in an eg, and not an obd2 b18b1 in an EG. From what I have read the B18b1 doesnt have the IAB either. Please correct me if I am wrong on anything and please steer me in the right direction.
