1990 acura integra hardwired obd1 conversion and is throwing ELD code 20. Looked up the ecu pin location for obd1 eld and it is D-10. However, i cannot find anything on where the ELD pin out is for the car which was previously obd0. Does the car just not have one? And if it doesnt how do i trick the obd1 ecu into thinking everything is cool?
