I just bought an JDM 2jz motor trying to do a swap on my N/A. The problem I'm having is that there's no spark. It's getting fuel but no spark on either coils. Also I was wondering about an extra plug on the engine harness going to the ECU? It's a white plug that's connected to the ecu plug.plus the airflow sensor is not hooked up . there are some extra plugs on the wiring haress that i do no where goes.
