I have a 93 ex coupe with a d16y8 out of a 98 ex running on a p28 ecu 5 speed trans. I am in the process of gather parts for a b20b i have the motor trans and some other things but I hear you can use the d series harness to swap the b20 in. My whole thing is obd questions. Seems to me the distributor is jumped from obd2 to obd1 pics included

Or do I have it backwards? So my thing is i have a p75 ecu I have a 99 obd2 b20b also a s1 ls trans what would i need to do to make things run right?
