so i traded my da for a crx si with a jdm front jdm rear seats and a odb2 b16 but the body was shot so bought a hf auto shell. i stripped out the si but didnt take the wire harness like a knuckle head. so my real question is what do i need to do wiring wise. when i got the car it had an 0db2 ecu with a odb2 to odb0 jumper harness and i believe the crx si wire harness. now the hf is all stock and auto so do i need to swap out a 5sp mpfi harness and do i need to swap out the dash harness from the si also thanks for all the help

i would really like to run the car odb1 casue my boy works at a honda shop and is a honda ecu guru and i know that the odb1 can be tuned much ezer than the odb2. so do i need to get a odb1 motor harness for the b16 and odb0 to odb1 jumper harness. ive done motor swaps before but never anything that required wiring

 

there were no auto HFs - only DXs came with automatic

 

get a obd0-obd1 jumper harness, obd1 ecu, run your stock HF harness, get a obd1 dizzy, and convert the dizzy plugs to obd1(or get the jumper). If you dont want to run the resistor box, get obd1 injector plugs and injectors and get the dead plug thing off an obd1 harness.

 

^^^ he got it. basicily being said is get the chassis to obd1, worry about the motor last, take the dizzy and rewire it from obd2 to obd1 and everything should plug in
