OBDII - OBD I Converstion

Hey guys:
I have a question in regards to re-wiring my OBDII ecu to an OBDI. I have a 97 Honda accord which i have recently put a H23 into. Everything in the swap has gone good so far but I am finding a hard time finding a wiring diagram for this converstion. It has probably already been posted on this site so i was hoping if anyone can help me out?

do you have an obd2-1 conversion harness? if so, things will go a lot easier...you will need to modify your original harness to accept the new sensors...

I thought if you were swapping engines, it was illeal to revert back to OBDI if you already had OBDII

Well i was trying to avoid spending $150 for a conversion harness, does anyone have a wiring diagram for the ecu for either a 93 prelude non-vtec or a 97 honda accord lx?
