Ok I have just done this swap. I have used the b16b harness on the b18c ITR motor. I am running a obd2b to obd2a conversion harness and the itr ECU. The car wont start. Sounds like the start sol is just clicking along with the main relay in the dash. I have swapped the starter motor out for the b16b one which I know was working 2 days ago. Same problem. Check voltage and I have 12volts at the starter. Put it on jumper cables off of another car just to be sure and the same problem. Noticed when pushing the car though with the ignition on the dash lights flickered on and off and the main relay clicked.
Any ideas on this would be great.
