ya thats the problem i been having i can find anything on step by step. i know my car is obd2 will the ecu that comes with the b16b is odb 2 aswell and will my d16y7 harness fit the ecu?
All you have to do is get an 99-00 civic si harness and its literally plug and play my friend, i did the same swap with the same previous motor.
That would be correct if he had a 99-2000 civic. But his is an obd2a so the 99 to 2000 si harness froma b16a2 would plug and play on the motor but it will be missing a plug for the ecu as the obd2b harness that it would be only has 2 plugs on the engine harness and one is connected to the dash loom.
