I have a 89 Crx HF with D15B Jspc. converted to obd 0 to obd 1 so there for i have no light to read on the ecu becuse im useing a P28 ecu if there is any one that can help me please do.

 

In my 88 it's near the driver's side shock tower (little connector in the engine bay with nothing plugged into it). In 90-91s (and maybe 89s.. not sure) it's in the passenger footwell. To the right of your ECU. Just stick in a paperclip in there and your light will start flashing.
